            COMMISSION DELEGATED REGULATION (EU) No 134/2014
of 16 December 2013
         
supplementing Regulation (EU) No 168/2013 of the European Parliament and of the Council with regard to environmental and propulsion unit performance requirements and amending Annex V thereof
(Text with EEA relevance)


THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,


Having regard to Regulation (EU) No 168/2013 of the European Parliament and of the Council of 15 January 2013 on the approval and market surveillance of two- or three-wheel vehicles and quadricycles (1), and in particular Article 18(3), Article 23(12), Article 24(3) and Article 74 thereof,

Whereas:







(1)


The term ‘L-category vehicles’ covers a wide range of light vehicle types with two, three or four wheels, e.g. powered cycles, two- and three-wheel mopeds, two- and three-wheel motorcycles, motorcycles with side-cars and light four-wheel vehicles (quadricycles) such as on-road quads, all-terrain quads and quadrimobiles.












(2)


Regulation (EU) No 168/2013 provides for the possibility of applying regulations of the United Nations Economic Commission for Europe (UNECE) for the purpose of EU whole vehicle type-approval. Under that Regulation, type-approval in accordance with UNECE regulations which apply on a compulsory basis is regarded as EU type-approval.












(3)


The compulsory application of UNECE regulations helps avoiding duplication not only of technical requirements but also of certification and administrative procedures. In addition, type-approval that is directly based on internationally agreed standards could improve market access in third countries, in particular those which are contracting parties to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (‘Revised 1958 Agreement’), acceded by the Union by Council Decision 97/836/EC (2), and thus enhance the Union industry’s competitiveness. However, to date the available UNECE regulations are either outdated or not existing and therefore these are revisited and upgraded for technical progress.












(4)


Therefore, Regulation (EU) No 168/2013 provides for the repeal of several directives concerning the approval of L-category vehicles, their systems, components and separate technical units intended for those vehicles in the areas of environmental and propulsion unit performance requirements. For the purposes of EU type-approval those directives should be replaced first with the provisions of this Regulation. On the long term, when the revisiting process at the level of the UN is finished, equivalent UNECE regulations will be available, which then will allow to replace the text of this Regulation with making reference to those UNECE regulations.












(5)


In particular UNECE regulation No 41 on noise emissions of categories L3e and L4e motorcycles was updated in 2011 for technical progress. UNECE regulation No 41 should therefore be made obligatory in EU type-approval legislation and replace Annex III to Chapter 9 of Directive 97/24/EC of the European Parliament and of the Council (3) in order for motorcycles to comply with only one set of motorcycle sound requirements, which are world-wide accepted by the contracting parties to the Revised 1958 Agreement. UNECE regulation No 85 on measurement of net power of electric motors should also be made obligatory with the same objective of mutual recognition between the contracting parties to the Revised 1958 Agreement in the area of propulsion unit performance requirements for electric motors.












(6)


The Euro 4 and 5 environmental steps are such measures designed to reduce emissions of particulate matter and ozone precursors such as nitrogen oxides and hydrocarbons. A considerable reduction in hydrocarbon emissions from L-category vehicles is necessary to improve air quality and comply The exhaust system which is granted system type-approval with limit values for pollution, not only directly to significantly reduce the disproportionately high hydrocarbon tailpipe and evaporative emissions from these vehicles, but also to help reduce volatile particle levels in urban areas and possibly also smog.












(7)


One of the measures against excessive hydrocarbon emissions from L-category vehicles is to limit the evaporative emissions to the hydrocarbon mass limits laid down in Annex VI(C) to Regulation (EU) No 168/2013. For this purpose, a type IV test has to be conducted at type-approval in order to measure the evaporative emissions of a vehicle. One of the requirements of the type IV Sealed House evaporative Emission Determination (SHED) test is to fit either a rapidly aged carbon canister or alternatively to apply an additive deterioration factor when fitting a degreened carbon canister. It will be investigated in the environmental effect study referred to in Article 23(4) of Regulation (EU) No 168/2013 whether or not it is cost effective to maintain this deterioration factor as alternative to fitting a representative and rapidly aged carbon canister. If the result of the study demonstrates that this method is not cost-effective a proposal will follow in due course to delete this alternative and should become applicable beyond the Euro 5 step.












(8)


A standardised method for measuring vehicles’ energy efficiency (fuel or energy consumption, carbon dioxide emissions as well as electric range) is necessary to ensure that no technical barriers to trade arise between Member States and also to ensure that customers and users are supplied with objective and precise information.












(9)


The methods for measuring propulsion unit performance including the maximum design vehicle speed, maximum torque and maximum continuous total power of L-category vehicles may differ from one Member State to the next, this might constitute barriers to trade within the Union. Therefore, it is necessary to draw up harmonised requirements for methods for measuring the propulsion unit performance of L-category vehicles in order to enable the approval of vehicles, systems, components or separate technical units to be applied for each type of such vehicle.












(10)


Functional safety or environmental requirements call for restrictions on tampering with certain types of L-category vehicles. In order to avoid obstacles to servicing and maintenance by vehicle owners, such restrictions should be strictly limited to tampering which significantly modifies the environmental and propulsion unit performance of the vehicle and functional safety in a harmful way. As harmful tampering of the vehicle’s powertrain affects both the environmental and functional safety performance, the detailed requirements regarding propulsion unit performance and noise abatement set out in this Regulation should also be used as reference for enforcement of powertrain tampering prevention.












(11)


Part A of Annex V to Regulation (EU) No 168/2013 makes reference to the 8 test types that allow assessment of the environmental performance of the L-category vehicle to be approved. It is appropriate to set out detailed test requirements in this delegated act as well as to amend Annex V (A) of Regulation (EU) No 168/2013 by linking the test limits agreed by Council and the European Parliament with detailed test procedures and technical requirements set out in this Regulation. A reference to the detailed test procedures and requirements set out in this Regulation should be inserted into Part A of Annex V to Regulation (EU) No 168/2013 by means of the amendments set out in Annex XII of this Regulation.

1.   Introduction









1.1.


This Annex sets out the procedure for type I testing, as referred to in Part A of Annex V to Regulation (EU) No 168/2013.












1.2.


This Annex provides a harmonised method for the determination of the levels of gaseous pollutant emissions and particulate matter, the emissions of carbon dioxide and is referred to in Annex VII to determine the fuel consumption, energy consumption and electric range of the L-category vehicle within the scope of Regulation (EU) No 168/2013 that are representative for real world vehicle operation.












1.1.1.


The ‘WMTC stage 1’ was introduced in EU type-approval legislation in 2006, which allowed manufacturers from then on to demonstrate the emission performance of the L3e motorcycle type by using the world harmonised motorcycle test cycle (WMTC) set out in UN GTR No 2 as alternative type I test to the use of the conventional European Driving Cycle (EDC) set out in Chapter 5 of Directive 97/24/EC.












1.1.2.


The ‘WMTC stage 2’ is equal to ‘WMTC stage 1’ with additional enhancements in the area of gear shift prescriptions and shall be used as compulsory type I test to approve Euro 4 compliant (sub-)categories L3e, L4e, L5e-A and L7e-A vehicles.












1.1.3.


The ‘revised WMTC’ or ‘WMTC stage 3’ is equal to ‘WMTC stage 2’ for L3e motorcycles, but contains also custom-tailored driving cycles for all other (sub-) category vehicles, used as type I test to approve Euro 5 compliant L-category vehicles.












1.2.


The results may form the basis for limiting gaseous pollutants, carbon dioxide and for the fuel consumption, energy consumption and electric range indicated by the manufacturer within the environmental performance type-approval procedures.




2.   General requirements









2.1.


The components liable to affect the emission of gaseous pollutants, carbon dioxide emissions and fuel consumption shall be so designed, constructed and assembled as to enable the vehicle in normal use, despite the vibration to which it may be subjected, to comply with the provisions of this Annex.

Note 1: The symbols used in Annex II are summarised in Appendix 1.












2.2.


Any hidden strategy that ‘optimises’ the powertrain of the vehicle running the relevant emission laboratory test cycle in an advantageous way, reducing tailpipe emissions and running significantly differently under real-world conditions, is considered a defeat strategy and is prohibited, unless the manufacturer has documented and declared it to the satisfaction of the approval authority.




3.   Performance requirements

The applicable performance requirements for EU type-approval are referred to in Parts A, B and C of Annex VI to Regulation (EU) No 168/2013.

4.1.1.   Test room
The test room with the chassis dynamometer and the gas sample collection device shall have a temperature of 298,2 ± 5 K (25 ± 5 °C). The room temperature shall be measured in the vicinity of the vehicle cooling blower (fan) before and after the type I test.
4.1.2.   Soak area
The soak area shall have a temperature of 298,2 ± 5 K (25 ± 5 °C) and be such that the test vehicle to be preconditioned can be parked in accordance with point 5.2.4. of this Annex.
4.2.   Test vehicle
4.2.1.   General
All components of the test vehicle shall conform to those of the production series or, if the vehicle is different from the production series, a full description shall be given in the test report.

4.2.2.   Run-in
The vehicle shall be presented in good mechanical condition, properly maintained and used. It shall have been run in and driven at least 1 000 km before the test. The engine, drive train and vehicle shall be properly run in, in accordance with the manufacturer’s requirements.
4.2.3.   Adjustments
The test vehicle shall be adjusted in accordance with the manufacturer’s requirements, e.g. as regards the viscosity of the oils, or, if it differs from the production series, a full description shall be given in the test report. In case of a four by four drive, the axle to which the lowest torque is delivered may be deactivated in order to allow testing on a standard chassis dynamometer.
4.2.4.   Test mass and load distribution
The test mass, including the masses of the rider and the instruments, shall be measured before the beginning of the tests. The load shall be distributed across the wheels in conformity with the manufacturer’s instructions.
4.2.5.   Tyres
The tyres shall be of a type specified as original equipment by the vehicle manufacturer. The tyre pressures shall be adjusted to the specifications of the manufacturer or to those where the speed of the vehicle during the road test and the vehicle speed obtained on the chassis dynamometer are equalised. The tyre pressure shall be indicated in the test report.
4.3.   L-category vehicle sub-classification

The appropriate reference fuels as specified in Appendix 2 shall be used for testing. For the purpose of the calculation referred to in point 1.4 of Appendix 1 of Annex VII, for liquid fuels, the density measured at 288,2 K (15 °C) shall be used.
4.5.   Type I test
4.5.1.   Driver
The test driver shall have a mass of 75 kg ± 5 kg.
4.5.2.   Test bench specifications and settings
4.5.2.1.   The dynamometer shall have a single roller for two-wheel L-category vehicles with a diameter of at least 400 mm. A chassis dynamometer equipped with dual rollers is permitted when testing tricycles with two front wheels or quadricycles.
4.5.2.2.   The dynamometer shall be equipped with a roller revolution counter for measuring actual distance travelled.
4.5.2.3.   Dynamometer flywheels or other means shall be used to simulate the inertia specified in point 5.2.2.
4.5.2.4.   The dynamometer rollers shall be clean, dry and free from anything which might cause the tyre to slip.
4.5.2.5.   Cooling fan specifications as follows:






4.5.2.5.1.


Throughout the test, a variable-speed cooling blower (fan) shall be positioned in front of the vehicle so as to direct the cooling air onto it in a manner that simulates actual operating conditions. The blower speed shall be such that, within the operating range of 10 to 50 km/h, the linear velocity of the air at the blower outlet is within ±5 km/h of the corresponding roller speed. At the range of over 50 km/h, the linear velocity of the air shall be within ± 10 percent. At roller speeds of less than 10 km/h, air velocity may be zero.










4.5.2.5.2.


The air velocity referred to in point 4.5.2.5.1. shall be determined as an averaged value of nine measuring points which are located at the centre of each rectangle dividing the whole of the blower outlet into nine areas (dividing both horizontal and vertical sides of the blower outlet into three equal parts). The value at each of the nine points shall be within 10 percent of the average of the nine values.










4.5.2.5.3.


The blower outlet shall have a cross-section area of at least 0.4 m2 and the bottom of the blower outlet shall be between 5 and 20 cm above floor level. The blower outlet shall be perpendicular to the longitudinal axis of the vehicle, between 30 and 45 cm in front of its front wheel. The device used to measure the linear velocity of the air shall be located at between 0 and 20 cm from the air outlet.




4.5.2.6.   The detailed requirements regarding test bench specifications are listed in Appendix 3.
4.5.3.   Exhaust gas measurement system
4.5.3.1.   The gas-collection device shall be a closed-type device that can collect all exhaust gases at the vehicle exhaust outlets on condition that it satisfies the backpressure condition of ± 125 mm H2O. An open system may be used if it is confirmed that all the exhaust gases are collected. The gas collection shall be such that there is no condensation which could appreciably modify the nature of exhaust gases at the test temperature. An example of a gas-collection device is illustrated in Figure 1-2:

Figure 1-2


Equipment for sampling the gases and measuring their volume






4.5.3.2.   A connecting tube shall be placed between the device and the exhaust gas sampling system. This tube and the device shall be made of stainless steel, or of some other material which does not affect the composition of the gases collected and which withstands the temperature of these gases.
4.5.3.3.   A heat exchanger capable of limiting the temperature variation of the diluted gases in the pump intake to ± 5 K shall be in operation throughout the test. This exchanger shall be equipped with a preheating system capable of bringing the exchanger to its operating temperature (with the tolerance of ± 5 K) before the test begins.
4.5.3.4.   A positive displacement pump shall be used to draw in the diluted exhaust mixture. This pump shall be equipped with a motor with several strictly controlled uniform speeds. The pump capacity shall be large enough to ensure the intake of the exhaust gases. A device using a critical-flow venturi (CFV) may also be used.
4.5.3.5.   A device (T) shall be used for the continuous recording of the temperature of the diluted exhaust mixture entering the pump.
4.5.3.6.   Two gauges shall be used, the first to ensure the pressure depression of the dilute exhaust mixture entering the pump relative to atmospheric pressure, and the second to measure the dynamic pressure variation of the positive displacement pump.
4.5.3.7.   A probe shall be located near to, but outside, the gas-collecting device, to collect samples of the dilution air stream through a pump, a filter and a flow meter at constant flow rates throughout the test.
4.5.3.8.   A sample probe pointed upstream into the dilute exhaust mixture flow, upstream of the positive displacement pump, shall be used to collect samples of the dilute exhaust mixture through a pump, a filter and a flow meter at constant flow rates throughout the test. The minimum sample flow rate in the sampling devices shown in Figure 1-2 and in point 4.5.3.7. shall be at least 150 litre/hour.
4.5.3.9.   Three-way valves shall be used on the sampling system described in points 4.5.3.7. and 4.5.3.8. to direct the samples either to their respective bags or to the outside throughout the test.
4.5.3.10.   Gas-tight collection bags
4.5.3.10.1.   For dilution air and dilute exhaust mixture the collection bags shall be of sufficient capacity not to impede normal sample flow and shall not change the nature of the pollutants concerned.
4.5.3.10.2.   The bags shall have an automatic self-locking device and shall be easily and tightly fastened either to the sampling system or the analysing system at the end of the test.
4.5.3.11.   A revolution counter shall be used to count the revolutions of the positive displacement pump throughout the test.

Note 2: Attention shall be paid to the connecting method and the material or configuration of the connecting parts, because each section (e.g. the adapter and the coupler) of the sampling system can become very hot. If the measurement cannot be performed normally due to heat damage to the sampling system, an auxiliary cooling device may be used as long as the exhaust gases are not affected.

Note 3: With open type devices, there is a risk of incomplete gas collection and gas leakage into the test cell. There shall be no leakage throughout the sampling period.

Note 4: If a constant volume sampler (CVS) flow rate is used throughout the test cycle that includes low and high speeds all in one (i.e. part 1, 2 and 3 cycles), special attention shall be paid to the higher risk of water condensation in the high speed range.
4.5.3.12.   Particulate mass emissions measurement equipment
4.5.3.12.1   Specification
4.5.3.12.1.1.   System overview
4.5.3.12.1.1.1.   The particulate sampling unit shall consist of a sampling probe located in the dilution tunnel, a particle transfer tube, a filter holder, a partial-flow pump, and flow rate regulators and measuring units.
4.5.3.12.1.1.2.   It is recommended that a particle size pre-classifier (e.g. cyclone or impactor) be employed upstream of the filter holder. However, a sampling probe, used as an appropriate size-classification device such as that shown in Figure 1-6, is acceptable.
4.5.3.12.1.2.   General requirements
4.5.3.12.1.2.1.   The sampling probe for the test gas flow for particulates shall be so arranged within the dilution tract that a representative sample gas flow can be taken from the homogeneous air/exhaust mixture.
4.5.3.12.1.2.2.   The particulate sample flow rate shall be proportional to the total flow of diluted exhaust gas in the dilution tunnel to within a tolerance of ±5 percent of the particulate sample flow rate.
4.5.3.12.1.2.3.   The sampled dilute exhaust gas shall be maintained at a temperature below 325,2 K (52 °C) within 20 cm upstream or downstream of the particulate filter face, except in the case of a regeneration test, where the temperature shall be below 465,2 K (192 °C).
4.5.3.12.1.2.4.   The particulate sample shall be collected on a single filter mounted in a holder in the sampled diluted exhaust gas flow
4.5.3.12.1.2.5.   All parts of the dilution system and the sampling system from the exhaust pipe up to the filter holder which are in contact with raw and diluted exhaust gas shall be designed to minimise deposition or alteration of the particulates. All parts shall be made of electrically conductive materials that do not react with exhaust gas components, and shall be electrically grounded to prevent electrostatic effects.
4.5.3.12.1.2.6.   If it is not possible to compensate for variations in the flow rate, provision shall be made for a heat exchanger and a temperature control device as specified in Appendix 4 so as to ensure that the flow rate in the system is constant and the sampling rate accordingly proportional.
4.5.3.12.1.3.   Specific requirements
4.5.3.12.1.3.1.   Particulate matter (PM) sampling probe
4.5.3.12.1.3.1.1.   The sample probe shall deliver the particle-size classification performance described in point 4.5.3.12.1.3.1.4. It is recommended that this performance be achieved by the use of a sharp-edged, open-ended probe facing directly in the direction of flow, plus a pre-classifier (cyclone impactor, etc.). An appropriate sampling probe, such as that indicated in Figure 1-1, may alternatively be used provided it achieves the pre-classification performance described in point 4.5.3.12.1.3.1.4.
4.5.3.12.1.3.1.2.   The sample probe shall be installed near the tunnel centreline between ten and 20 tunnel diameters downstream of the exhaust gas inlet to the tunnel and have an internal diameter of at least 12 mm.
If more than one simultaneous sample is drawn from a single sample probe, the flow drawn from that probe shall be split into identical sub-flows to avoid sampling artefacts.
If multiple probes are used, each probe shall be sharp-edged, open-ended and facing directly into the direction of flow. Probes shall be equally spaced at least 5 cm apart around the central longitudinal axis of the dilution tunnel.
4.5.3.12.1.3.1.3.   The distance from the sampling tip to the filter mount shall be at least five probe diameters, but shall not exceed 1 020 mm.
4.5.3.12.1.3.1.4.   The pre-classifier (e.g. cyclone, impactor, etc.) shall be located upstream of the filter holder assembly. The pre-classifier 50 percent cut point particle diameter shall be between 2.5 μm and 10 μm at the volumetric flow rate selected for sampling particulate mass emissions. The pre-classifier shall allow at least 99 percent of the mass concentration of 1 μm particles entering the pre-classifier to pass through the exit of the pre-classifier at the volumetric flow rate selected for sampling particulate mass emissions. However, a sampling probe, used as an appropriate size-classification device, such as that shown in Figure 1-6, is acceptable as an alternative to a separate pre-classifier.
4.5.3.12.1.3.2.   Sample pump and flow meter
4.5.3.12.1.3.2.1.   The sample gas flow measurement unit shall consist of pumps, gas flow regulators and flow measuring units.
4.5.3.12.1.3.2.2.   The temperature of the gas flow in the flow meter may not fluctuate by more than ±3 K, except during regeneration tests on vehicles equipped with periodically regenerating after-treatment devices. In addition, the sample mass flow rate shall remain proportional to the total flow of diluted exhaust gas to within a tolerance of ± 5 percent of the particulate sample mass flow rate. Should the volume of flow change unacceptably as a result of excessive filter loading, the test shall be stopped. When the test is repeated, the rate of flow shall be decreased.
4.5.3.12.1.3.3.   Filter and filter holder
4.5.3.12.1.3.3.1.   A valve shall be located downstream of the filter in the direction of flow. The valve shall be responsive enough to open and close within one second of the start and end of the test.
4.5.3.12.1.3.3.2.   It is recommended that the mass collected on the 47 mm diameter filter (Pe) is ≥ 20 μg and that the filter loading is maximised in line with the requirements of points 4.5.3.12.1.2.3. and 4.5.3.12.1.3.3.
4.5.3.12.1.3.3.3.   For a given test, the gas filter face velocity shall be set to a single value within the range 20 cm/s to 80 cm/s, unless the dilution system is being operated with sampling flow proportional to CVS flow rate.
4.5.3.12.1.3.3.4.   Fluorocarbon coated glass fibre filters or fluorocarbon membrane filters are required. All filter types shall have a 0,3 μm DOP (di-octylphthalate) or PAO (poly-alpha-olefin) CS 68649-12-7 or CS 68037-01-4 collection efficiency of at least 99 percent at a gas filter face velocity of 5,33 cm/s.
4.5.3.12.1.3.3.5.   The filter holder assembly shall be of a design that provides an even flow distribution across the filter stain area. The filter stain area shall be at least 1 075 mm2.
4.5.3.12.1.3.4.   Filter weighing chamber and balance
4.5.3.12.1.3.4.1.   The microgram balance used to determine the weight of a filter shall have a precision (standard deviation) of 2 μg and resolution of 1 μg or better.
It is recommended that the microbalance be checked at the start of each weighing session by weighing one reference weight of 50 mg. This weight shall be weighed three times and the average result recorded. The weighing session and balance are considered valid if the average result of the weighing is within ± 5 μg of the result from the previous weighing session.
The weighing chamber (or room) shall meet the following conditions during all filter conditioning and weighing operations:






—


Temperature maintained at 295,2 ± 3 K (22 ± 3 °C);










—


Relative humidity maintained at 45 ± 8 percent;










—


Dew point maintained at 282,7 ± 3 K (9,5 ± 3 °C).




It is recommended that temperature and humidity conditions be recorded along with sample and reference filter weights.
4.5.3.12.1.3.4.2.   Buoyancy correction
All filter weights shall be corrected for filter buoyancy in air.
The buoyancy correction depends on the density of the sample filter medium, the density of air, and the density of the calibration weight used to calibrate the balance. The density of the air is dependent on the pressure, temperature and humidity.
It is recommended that the temperature and dew point of the weighing environment be controlled to 295,2 K ± 1 K (22 °C ± 1 °C) and 282,7 ± 1 K (9,5 ± 1 °C) respectively. However, the minimum requirements stated in point 4.5.3.12.1.3.4.1. will also result in an acceptable correction for buoyancy effects. The correction for buoyancy shall be applied as follows:

Equation 2-1:






where:







mcorr



=


PM mass corrected for buoyancy




muncorr



=


PM mass uncorrected for buoyancy




ρair



=


density of air in balance environment




ρweight



=


density of calibration weight used to span balance




ρmedia



=


density of PM sample medium (filter) with filter medium Teflon coated glass fibre (e.g. TX40): ρmedia = 2,300 kg/m3





ρair can be calculated as follows:

Equation 2-2:






where:







Pabs



=


absolute pressure in balance environment




Mmix



=


molar mass of air in balance environment (28,836 gmol-1)




R


=


molar gas constant (8,314 Jmol-1K-1)




Tamb



=


absolute ambient temperature of balance environment




The chamber (or room) environment shall be free of any ambient contaminants (such as dust) that would settle on the particulate filters during their stabilisation.
Limited deviations from weighing room temperature and humidity specifications shall be allowed provided their total duration does not exceed 30 minutes in any one filter conditioning period. The weighing room shall meet the required specifications prior to personal entrance into the weighing room. No deviations from the specified conditions are permitted during the weighing operation.
4.5.3.12.1.3.4.3.   The effects of static electricity shall be nullified. This may be achieved by grounding the balance through placement on an antistatic mat and neutralisation of the particulate filters prior to weighing using a Polonium neutraliser or a device of similar effect. Alternatively, nullification of static effects may be achieved through equalisation of the static charge.
4.5.3.12.1.3.4.4.   A test filter shall be removed from the chamber no earlier than an hour before the test begins.
4.5.3.12.1.4.   Recommended system description
Figure 1-3 is a schematic drawing of the recommended particulate sampling system. Since various configurations can produce equivalent results, exact conformity with this figure is not required. Additional components such as instruments, valves, solenoids, pumps and switches may be used to provide additional information and coordinate the functions of component systems. Further components that are not needed to maintain accuracy with other system configurations may be excluded if their exclusion is based on good engineering judgment.

Figure 1-3


Particulate sampling system






A sample of the diluted exhaust gas is taken from the full flow dilution tunnel (DT) through the particulate sampling probe (PSP) and the particulate transfer tube (PTT) by means of the pump (P). The sample is passed through the particle size pre-classifier (PCF) and the filter holders (FH) that contain the particulate sampling filters. The flow rate for sampling is set by the flow controller (FC).
4.5.4.   Driving schedules
4.5.4.1.   Test cycles
Test cycles (vehicle speed patterns) for the type I test consist of up to three parts, as laid down in Appendix 6. Depending on the vehicle (sub-)category, the following test cycle parts must be run:

4.5.4.2.   Vehicle speed tolerances
4.5.4.2.1.   The vehicle speed tolerance at any given time on the test cycles prescribed in point 4.5.4.1. is defined by upper and lower limits. The upper limit is 3,2 km/h higher than the highest point on the trace within one second of the given time. The lower limit is 3,2 km/h lower than the lowest point on the trace within one second of the given time. Vehicle speed variations greater than the tolerances (such as may occur during gear changes) are acceptable provided they occur for less than two seconds on any occasion. Vehicle speeds lower than those prescribed are acceptable provided the vehicle is operated at maximum available power during such occurrences. Figure 1-4 shows the range of acceptable vehicle speed tolerances for typical points.

Drivers trace, allowable range







4.5.4.2.2.   If the acceleration capability of the vehicle is not sufficient to carry out the acceleration phases or if the maximum design speed of the vehicle is lower than the prescribed cruising speed within the prescribed limits of tolerances, the vehicle shall be driven with the throttle fully open until the set speed is reached or at the maximum design speed achievable with fully opened throttle during the time that the set speed exceeds the maximum design speed. In both cases, point 4.5.4.2.1. is not applicable. The test cycle shall be carried on normally when the set speed is again lower than the maximum design speed of the vehicle.
4.5.4.2.3.   If the period of deceleration is shorter than that prescribed for the corresponding phase, the set speed shall be restored by a constant vehicle speed or idling period merging into succeeding constant speed or idling operation. In such cases, point 4.5.4.2.1. is not applicable.
4.5.4.2.4.   Apart from these exceptions, the deviations of the roller speed from the set speed of the cycles shall meet the requirements described in point 4.5.4.2.1. If not, the test results shall not be used for further analysis and the run must be repeated.

4.5.5.1.   Test vehicles with automatic transmission
4.5.5.1.1.   Vehicles equipped with transfer cases, multiple sprockets, etc., shall be tested in the configuration recommended by the manufacturer for street or highway use.
4.5.5.1.2.   All tests shall be conducted with automatic transmissions in ‘Drive’ (highest gear). Automatic clutch-torque converter transmissions may be shifted as manual transmissions at the request of the manufacturer.
4.5.5.1.3.   Idle modes shall be run with automatic transmissions in ‘Drive’ and the wheels braked.
4.5.5.1.4.   Automatic transmissions shall shift automatically through the normal sequence of gears. The torque converter clutch, if applicable, shall operate as under real-world conditions.
4.5.5.1.5.   The deceleration modes shall be run in gear using brakes or throttle as necessary to maintain the desired speed.

                                    ’ is the idling speed in min-1

                                    ‘ndvi
                                    ’ is the ratio between engine speed in min-1 and vehicle speed in km/h in gear ‘i’

The appropriate gear for each sample shall then be calculated according to the vehicle speed ranges resulting from the shift speed equations of point 4.5.5.2.1.1. and the phase indicators for the cycle parts appropriate for the test vehicle, as follows:






 


Gear choice for stop phases:
For the last five seconds of a stop phase, the gear lever shall be set to gear 1 and the clutch shall be disengaged. For the previous part of a stop phase, the gear lever shall be set to neutral or the clutch shall be disengaged.

The clutch shall be disengaged, if:






(a)


the vehicle speed drops below 10 km/h, or










(b)

the engine speed drops below 



;









(c)


there is a risk of engine stalling during cold-start phase.




4.5.5.2.3.   Step 3 — Corrections according to additional requirements
4.5.5.2.3.1.   The gear choice shall be modified according to the following requirements:






(a)


no gearshift at a transition from an acceleration phase to a deceleration phase. The gear that was used for the last second of the acceleration phase shall be kept for the following deceleration phase unless the speed drops below a downshift speed;










(b)


no upshifts or downshifts by more than one gear, except from gear 2 to neutral during decelerations down to stop;










(c)


upshifts or downshifts for up to four seconds are replaced by the gear before, if the gears before and after are identical, e.g. 2 3 3 3 2 shall be replaced by 2 2 2 2 2, and 4 3 3 3 3 4 shall be replaced by 4 4 4 4 4 4. In the cases of consecutive circumstances, the gear used longer takes over, e.g. 2 2 2 3 3 3 2 2 2 2 3 3 3 will be replaced by 2 2 2 2 2 2 2 2 2 2 3 3 3. If used for the same time, a series of succeeding gears shall take precedence over a series of preceding gears, e.g. 2 2 2 3 3 3 2 2 2 3 3 3 will be replaced by 2 2 2 2 2 2 2 2 2 3 3 3;










(d)


no downshift during an acceleration phase.




4.5.5.2.2.   Optional provisions
The gear choice may be modified according to the following provisions:
The use of gears lower than those determined by the requirements described in point 4.5.5.2.1. is permitted in any cycle phase. Manufacturers’ recommendations for gear use shall be followed if they do not result in gears higher than determined by the requirements of point 4.5.5.2.1.

Explanations of the approach and the gearshift strategy and a calculation example are given in Appendix 9.
4.5.6.   Dynamometer settings
A full description of the chassis dynamometer and instruments shall be provided in accordance with Appendix 6. Measurements shall be taken to the accuracies specified in point 4.5.7. The running resistance force for the chassis dynamometer settings can be derived either from on-road coast-down measurements or from a running resistance table, with reference to Appendix 5 or 7 for a vehicle equipped with one wheel on the powered axle and to Appendix 8 for a vehicle with two or more wheels on the powered axles.
4.5.6.1.   Chassis dynamometer setting derived from on-road coast-down measurements
To use this alternative, on-road coast-down measurements shall be carried out as specified in Appendix 7 for a vehicle equipped with one wheel on the powered axle and Appendix 8 for a vehicle equipped with two or more wheels on the powered axles.
4.5.6.1.1.   Requirements for the equipment
The instrumentation for the speed and time measurement shall have the accuracies specified in point 4.5.7.
4.5.6.1.2.   Inertia mass setting
4.5.6.1.2.1.   The equivalent inertia mass mi for the chassis dynamometer shall be the flywheel equivalent inertia mass, mfi, closest to the sum of the mass in running order of the vehicle and the mass of the driver (75 kg). Alternatively, the equivalent inertia mass mi can be derived from Appendix 5.
4.5.6.1.2.2.   If the reference mass mref
 cannot be equalised to the flywheel equivalent inertia mass mi, to make the target running resistance force F* equal to the running resistance force FE (which is to be set to the chassis dynamometer), the corrected coast-down time ΔTE may be adjusted in accordance with the total mass ratio of the target coast-down time ΔTroad in the following sequence:

4.5.6.2.   Running resistance force derived from a running resistance table
4.5.6.2.1.   The chassis dynamometer may be set by the use of the running resistance table instead of the running resistance force obtained by the coast-down method. In this table method, the chassis dynamometer shall be set by the mass in running order regardless of particular L-category vehicle characteristics.

Note 6: Care shall be taken when applying this method to L-category vehicles with extraordinary characteristics.
4.5.6.2.2.   The flywheel equivalent inertia mass mfi shall be the equivalent inertia mass mi specified in Appendix 5, 7 or 8 where applicable. The chassis dynamometer shall be set by the rolling resistance of the non-driven wheels (a) and the aero drag coefficient (b) specified in Appendix 5 or determined in accordance with the procedures set out in Appendix 7 or 8 respectively.
4.5.6.2.3   The running resistance force on the chassis dynamometer FE shall be determined using the following equation:

Equation 2-14:






4.5.6.2.4.   The target running resistance force F* shall be equal to the running resistance force obtained from the running resistance table FT, because the correction for the standard ambient conditions is not necessary.

5.2.   Type I tests
5.2.1.   Overview
5.2.1.1.   The type I test consists of prescribed sequences of dynamometer preparation, fuelling, parking, and operating conditions.
5.2.1.2.   The test is designed to determine hydrocarbon, carbon monoxide, oxides of nitrogen, carbon dioxide, particulate matter mass emissions if applicable and fuel / energy consumption as well as electric range while simulating real-world operation. The test consists of engine start-ups and L-category vehicle operation on a chassis dynamometer, through a specified driving cycle. A proportional part of the diluted exhaust emissions is collected continuously for subsequent analysis, using a constant volume (variable dilution) sampler (CVS).
5.2.1.3.   Except in cases of component malfunction or failure, all emission-control systems installed on or incorporated in a tested L-category vehicle shall be functioning during all procedures.
5.2.1.4.   Background concentrations are measured for all emission constituents for which emissions measurements are taken. For exhaust testing, this requires sampling and analysis of the dilution air.
5.2.1.5.   Background particulate mass measurement
The particulate background level of the dilution air may be determined by passing filtered dilution air through the particulate filter. This shall be drawn from the same point as the particulate matter sample, if a particulate mass measurement is applicable according to Annex VI(A) to Regulation (EU) No 168/2013. One measurement may be performed prior to or after the test. Particulate mass measurements may be corrected by subtracting the background contribution from the dilution system. The permissible background contribution shall be ≤ 1 mg/km (or equivalent mass on the filter). If the background contribution exceeds this level, the default figure of 1 mg/km (or equivalent mass on the filter) shall be used. Where subtraction of the background contribution gives a negative result, the particulate mass result shall be considered to be zero.
5.2.2.   Dynamometer settings and verification
5.2.2.1.   Test vehicle preparation
5.2.2.1.1.   The manufacturer shall provide additional fittings and adapters, as required to accommodate a fuel drain at the lowest point possible in the tanks as installed on the vehicle, and to provide for exhaust sample collection.
5.2.2.1.2.   The tyre pressures shall be adjusted to the manufacturer’s specifications to the satisfaction of the technical service or so that the speed of the vehicle during the road test and the vehicle speed obtained on the chassis dynamometer are equal.
5.2.2.1.3.   The test vehicle shall be warmed up on the chassis dynamometer to the same condition as it was during the road test.
5.2.2.2.   Dynamometer preparation, if settings are derived from on-road coast-down measurements
Before the test, the chassis dynamometer shall be appropriately warmed up to the stabilised frictional force Ff. The load on the chassis dynamometer FE is, in view of its construction, composed of the total friction loss Ff, which is the sum of the chassis dynamometer rotating frictional resistance, the tyre rolling resistance, the frictional resistance of the rotating parts in the powertrain of the vehicle and the braking force of the power absorbing unit (pau) Fpau, as in the following equation:

Equation 2-15:






The target running resistance force F* derived from Appendix 5 or 7 for a vehicle equipped with one wheel on the powered axle and Appendix 8 for a vehicle with two or more wheels on the powered axles, shall be reproduced on the chassis dynamometer in accordance with the vehicle speed, i.e.:

Equation 2-16:






The total friction loss Ff on the chassis dynamometer shall be measured by the method in point 5.2.2.2.1. or 5.2.2.2.2.
5.2.2.2.1.   Motoring by chassis dynamometer
This method applies only to chassis dynamometers capable of driving an L-category vehicle. The test vehicle shall be driven steadily by the chassis dynamometer at the reference speed v0 with the drive train engaged and the clutch disengaged. The total friction loss Ff (v0) at the reference speed v0 is given by the chassis dynamometer force.
5.2.2.2.2.   Coast-down without absorption
The method for measuring the coast-down time is the coast-down method for the measurement of the total friction loss Ff. The vehicle coast-down shall be performed on the chassis dynamometer by the procedure described in Appendix 5 or 7 for a vehicle equipped with one wheel on the powered axle and Appendix 8 for a vehicle equipped with two or more wheels on the powered axles, with zero chassis dynamometer absorption. The coast-down time Δti corresponding to the reference speed v0 shall be measured. The measurement shall be carried out at least three times, and the mean coast-down time 

 shall be calculated using the following equation:

Equation 2-19:






5.2.2.2.5.   Chassis dynamometer setting
Depending on its type, the chassis dynamometer shall be set by one of the methods described in points 5.2.2.2.5.1. to 5.2.2.2.5.4.

5.2.2.2.5.1.   Chassis dynamometer with polygonal function
In the case of a chassis dynamometer with polygonal function, in which the absorption characteristics are determined by load values at several speed points, at least three specified speeds, including the reference speed, shall be chosen as the setting points. At each setting point, the chassis dynamometer shall be set to the value Fpau (vj) obtained in point 5.2.2.2.4.
5.2.2.2.5.2.   Chassis dynamometer with coefficient control
In the case of a chassis dynamometer with coefficient control, in which the absorption characteristics are determined by given coefficients of a polynomial function, the value of Fpau (vj) at each specified speed shall be calculated by the procedure in point 5.2.2.2.
Assuming the load characteristics to be:

Equation 2-20:






where:
the coefficients a, b and c shall be determined by the polynomial regression method.
The chassis dynamometer shall be set to the coefficients a, b and c obtained by the polynomial regression method.
5.2.2.2.5.3.   Chassis dynamometer with F* polygonal digital setter
In the case of a chassis dynamometer with a polygonal digital setter, where a central processor unit is incorporated in the system, F*is input directly, and Δti, Ff and Fpau are automatically measured and calculated to set the chassis dynamometer to the target running resistance force:

Equation 2-21:






In this case, several points in succession are directly input digitally from the data set of F*
j and vj, the coast-down is performed and the coast-down time Δtj is measured. After the coast-down test has been repeated several times, Fpau is automatically calculated and set at L-category vehicle speed intervals of 0,1 km/h, in the following sequence:

Equation 2-22:







Equation 2-23:







Equation 2-24:

0, f*
2 coefficient digital setter
In the case of a chassis dynamometer with a coefficient digital setter, where a central processor unit is incorporated in the system, the target running resistance force 

 is automatically set on the chassis dynamometer.
In this case, the coefficients f*
0 and f*
2 are directly input digitally; the coast-down is performed and the coast-down time Δti is measured. Fpau is automatically calculated and set at vehicle speed intervals of 0,06 km/h, in the following sequence:

The measurement shall be carried out at least three times, and the mean coast-down time ΔtE shall be calculated from the results. The set running resistance force at the reference speed, FE (v0) on the chassis dynamometer is calculated by the following equation:

Equation 2-28:

ε ≤ 3 percent for 30 km/h ≤ v0< 50 km/h










 


ε ≤ 10 percent for v0< 30 km/h




The procedure in points 5.2.2.2.6.1. to 5.2.2.2.6.2. shall be repeated until the setting error satisfies the criteria. The chassis dynamometer setting and the observed errors shall be recorded. Specimen record forms are provided in the template of the test report laid down in accordance with Article 32(1) of Regulation (EU) No 168/2013.

The range of specified vehicle speed points (the interval between the maximum and minimum points) shall extend either side of the reference speed or the reference speed range, if there is more than one reference speed, by at least Δv, as defined in Appendix 5 or 7 for a vehicle equipped with one wheel on the powered axle and in Appendix 8 for a vehicle with two or more wheels on the powered axles. The specified speed points, including the reference speed points, shall be at regular intervals of no more than 20 km/h apart.
5.2.2.3.2.   Verification of chassis dynamometer
5.2.2.3.2.1.   Immediately after the initial setting, the coast-down time on the chassis dynamometer corresponding to the specified speed shall be measured. The vehicle shall not be set up on the chassis dynamometer during the coast-down time measurement. The coast-down time measurement shall start when the chassis dynamometer speed exceeds the maximum speed of the test cycle.
5.2.2.3.2.2.   The measurement shall be carried out at least three times, and the mean coast-down time ΔtE shall be calculated from the results.

To determine the specific reference filter weights, at least two unused reference filters shall be weighed within eight hours of, but preferably at the same time as, the sample filter weighing. Reference filters shall be of the same size and material as the sample filter.
If the specific weight of any reference filter changes by more than ± 5 μg between sample filter weighings, the sample filter and reference filters shall be reconditioned in the weighing room and then reweighed.
This shall be based on a comparison of the specific weight of the reference filter and the rolling average of that filter’s specific weights.
The rolling average shall be calculated from the specific weights collected in the period since the reference filters were placed in the weighing room. The averaging period shall be between one day and 30 days.
Multiple reconditioning and reweighings of the sample and reference filters are permitted up to 80 hours after the measurement of gases from the emissions test.
If, within this period, more than half the reference filters meet the ± 5 μg criterion, the sample filter weighing can be considered valid.
If, at the end of this period, two reference filters are used and one filter fails to meet the ± 5 μg criterion, the sample filter weighing may be considered valid provided that the sum of the absolute differences between specific and rolling averages from the two reference filters is no more than 10 μg.
If fewer than half of the reference filters meet the ± 5 μg criterion, the sample filter shall be discarded and the emissions test repeated. All reference filters shall be discarded and replaced within 48 hours.
In all other cases, reference filters shall be replaced at least every 30 days and in such a manner that no sample filter is weighed without comparison with a reference filter that has been in the weighing room for at least one day.
If the weighing room stability criteria outlined in point 4.5.3.12.1.3.4. are not met but the reference filter weighings meet the criteria listed in point 5.2.3.5.3, the vehicle manufacturer has the option of accepting the sample filter weights or voiding the tests, fixing the weighing room control system and re-running the test.

6.1.1.5.1.   With repeated measurements (see point 5.1.1.2.), the pollutant (mg/km), and CO2 emission results obtained by the calculation method described in point 6.1.1. and fuel / energy consumption and electric range determined according to Annex VII are averaged for each cycle part.
6.1.1.5.1.1   Weighting of results from UNECE regulation No 40 and regulation No 47 test cycles
The (average) result of the cold phase of UNECE regulation No 40 and of regulation No 47 test cycle is called R1; the (average) result of the warm phase of UNECE regulation No 40 and of regulation No 47 test cycle is called R2. Using these pollutant (mg/km) and CO2 (g/km) emission results, the final result R, depending on the vehicle class as defined in point 6.3., shall be calculated using the following equations:

Equation 2-52:






where:







w1



=

w2



=


weighting factor warm phase




6.1.1.5.1.2   Weighting of WMTC results
The (average) result of Part 1 or Part 1 reduced vehicle speed is called R1, the (average) result of Part 2 or Part 2 reduced vehicle speed is called R2 and the (average) result of Part 3 or part 3 reduced vehicle speed is called R3. Using these emission (mg/km) and fuel consumption (litres/100 km) results, the final result R, depending on the vehicle category as defined in point 6.1.1.6.2., shall be calculated using the following equations:

Equation 2-53:






where:







w1



=


weighting factor cold phase




w2



=

2.   Dynamometer calibration procedure

2.1.   Introduction
This section describes the method to be used to determine the load absorbed by a dynamometer brake. The load absorbed comprises the load absorbed by frictional effects and the load absorbed by the power-absorption device. The dynamometer is brought into operation beyond the range of test speeds. The device used for starting up the dynamometer is then disconnected; the rotational speed of the driven roller decreases. The kinetic energy of the rollers is dissipated by the power-absorption unit and by the frictional effects. This method disregards variations in the roller’s internal frictional effects caused by rollers with or without the vehicle. The frictional effects of the rear roller shall be disregarded when the roller is free.
2.2.   Calibration of the load indicator at 80 km/h or of the load indicator referred to in point 1.1.3.1. for vehicles that cannot attain 80 km/h.
The following procedure shall be used for calibration of the load indicator to 80 km/h or the applicable load indicator referred to in point 1.1.3.1. for vehicles that cannot attain 80 km/h, as a function of the load absorbed (see also Figure Ap3-1):
2.2.1.   Measure the rotational speed of the roller if this has not already been done. A fifth wheel, a revolution counter or some other method may be used.
2.2.2.   Place the vehicle on the dynamometer or devise some other method for starting up the dynamometer.
2.2.3.   Use the flywheel or any other system of inertia simulation for the particular inertia class to be used.

The load-absorption curve of the dynamometer from a reference setting at a speed of 80 km/h or for vehicles that cannot attain 80 km/h at the respective reference vehicle speeds referred to in point 1.1.3.1., shall be verified as follows:






3.1.1.


Place the vehicle on the dynamometer or devise some other method for starting up the dynamometer.










3.1.2.


Adjust the dynamometer to the absorbed load (F80) at 80 km/h, or for vehicles that cannot attain 80 km/h to the absorbed load Fvj at the respective target vehicle speed vj referred to in point 1.1.3.1.

3.1.5.


Repeat the procedure set out in points 3.1.1. to 3.1.4. for other values of F80 and for other values of inertia.




4   Verification of simulated inertia

4.1.   Object
The method described in this Appendix makes it possible to check that the simulated total inertia of the dynamometer is carried out satisfactorily in the running phase of the operating cycle. The manufacturer of the chassis dynamometer shall specify a method for verifying the specifications according to point 4.3.
4.2.   Principle
4.2.1.   Drawing-up working equations
Since the dynamometer is subjected to variations in the rotating speed of the roller(s), the force at the surface of the roller(s) can be expressed by:

Equation Ap3-3:






where:






 


F is the force at the surface of the roller(s) in N;










 


I is the total inertia of the dynamometer (equivalent inertia of the vehicle);










 


IM is the inertia of the mechanical masses of the dynamometer;










 


γ is the tangential acceleration at roller surface;










 


F1 is the inertia force.





Note: An explanation of this formula with reference to dynamometers with mechanically simulated inertia is appended.
Thus, total inertia is expressed as follows:

Equation Ap3-4:






where:






 


Im can be calculated or measured by traditional methods;










 


F1 can be measured on the dynamometer;










 


γ can be calculated from the peripheral speed of the rollers.




The total inertia (I) will be determined during an acceleration or deceleration test with values no lower than those obtained on an operating cycle.
4.2.2.   Specification for the calculation of total inertia
The test and calculation methods shall make it possible to determine the total inertia I with a relative error (ΔI/I) of less than ± 2 percent.
4.3.   Specification
4.3.1.   The mass of the simulated total inertia I shall remain the same as the theoretical value of the equivalent inertia (see Appendix 5) within the following limits:






4.3.1.1.


± 5 percent of the theoretical value for each instantaneous value;










4.3.1.2.


± 2 percent of the theoretical value for the average value calculated for each sequence of the cycle.
The limit specified in point 4.3.1.1. is brought to ± 50 percent for one second when starting and, for vehicles with manual transmission, for two seconds during gear changes.




4.4.   Verification procedure
4.4.1.   Verification is carried out during each test throughout the test cycles defined in Appendix 6 of Annex II.
4.4.2.   However, if the requirements laid down in point 4.3. are met, with instantaneous accelerations which are at least three times greater or smaller than the values obtained in the sequences of the theoretical cycle, the verification described in point 4.4.1. will not be necessary.




Appendix 4

Exhaust dilution system

1.   System specification

1.1.   System overview
A full-flow exhaust dilution system shall be used. This requires that the vehicle exhaust be continuously diluted with ambient air under controlled conditions. The total volume of the mixture of exhaust and dilution air shall be measured and a continuously proportional sample of the volume shall be collected for analysis. The quantities of pollutants are determined from the sample concentrations, corrected for the pollutant content of the ambient air and the totalised flow over the test period. The exhaust dilution system shall consist of a transfer tube, a mixing chamber and dilution tunnel, a dilution air conditioning, a suction device and a flow measurement device. Sampling probes shall be fitted in the dilution tunnel as specified in Appendices 3, 4 and 5. The mixing chamber described in this point shall be a vessel, such as those illustrated in Figures Ap4-1 and Ap4-2, in which vehicle exhaust gases and the dilution air are combined so as to produce a homogeneous mixture at the chamber outlet.
1.2.   General requirements
1.2.1.   The vehicle exhaust gases shall be diluted with a sufficient amount of ambient air to prevent any water condensation in the sampling and measuring system under any conditions which may occur during a test.
1.2.2.   The mixture of air and exhaust gases shall be homogeneous at the point where the sampling probe is located (see point 1.3.3.). The sampling probe shall extract a representative sample of the diluted exhaust gas.
1.2.3.   The system shall enable the total volume of the diluted exhaust gases to be measured.
1.2.4.   The sampling system shall be gas-tight. The design of the variable dilution sampling system and the materials that go to make it up shall be such that they do not affect the pollutant concentration in the diluted exhaust gases. Should any component in the system (heat exchanger, cyclone separator, blower, etc.) change the concentration of any of the pollutants in the diluted exhaust gases and the fault cannot be corrected, sampling for that pollutant shall be carried out upstream from that component.
1.2.5.   All parts of the dilution system that are in contact with raw and diluted exhaust gas shall be designed to minimise deposition or alteration of the particulates or particles. All parts shall be made of electrically conductive materials that do not react with exhaust gas components and shall be electrically grounded to prevent electrostatic effects.
1.2.6.   If the vehicle being tested is equipped with an exhaust pipe comprising several branches, the connecting tubes shall be connected as near as possible to the vehicle without adversely affecting its operation.
1.2.7.   The variable-dilution system shall be designed so as to enable the exhaust gases to be sampled without appreciably changing the back-pressure at the exhaust pipe outlet.
1.2.8.   The connecting tube between the vehicle and dilution system shall be so designed as to minimise heat loss.
1.3.   Specific requirements
1.3.1.   Connection to vehicle exhaust
The connecting tube between the vehicle exhaust outlets and the dilution system shall be as short as possible and satisfy the following requirements:






(a)


the tube shall be less than 3,6 m long, or less than 6,1 m long if heat insulated. Its internal diameter may not exceed 105 mm;










(b)


it shall not cause the static pressure at the exhaust outlets on the test vehicle to differ by more than ± 0,75 kPa at 50 km/h, or more than ± 1,25 kPa for the whole duration of the test, from the static pressures recorded when nothing is connected to the vehicle exhaust outlets. The pressure shall be measured in the exhaust outlet or in an extension having the same diameter, as near as possible to the end of the pipe. Sampling systems capable of maintaining the static pressure to within ± 0,25 kPa may be used if a written request from a manufacturer to the technical service substantiates the need for the closer tolerance;










(c)


it shall not change the nature of the exhaust gas;










(d)


any elastomeric connectors employed shall be as thermally stable as possible and have minimum exposure to the exhaust gases.




1.3.2.   Dilution air conditioning
The dilution air used for the primary dilution of the exhaust in the CVS tunnel shall be passed through a medium capable of reducing particles in the most penetrating particle size of the filter material by ≥ 99,95 percent, or through a filter of at least class H13 of EN 1822:1998. This represents the specification of High Efficiency Particulate Air (HEPA) filters. The dilution air may be charcoal scrubbed before being passed to the HEPA filter. It is recommended that an additional coarse particle filter is situated before the HEPA filter and after the charcoal scrubber, if used. At the vehicle manufacturer’s request, the dilution air may be sampled according to good engineering practice to determine the tunnel contribution to background particulate mass levels, which can then be subtracted from the values measured in the diluted exhaust.
1.3.3.   Dilution tunnel
Provision shall be made for the vehicle exhaust gases and the dilution air to be mixed. A mixing orifice may be used. In order to minimise the effects on the conditions at the exhaust outlet and to limit the drop in pressure inside the dilution-air conditioning device, if any, the pressure at the mixing point shall not differ by more than ± 0,25 kPa from atmospheric pressure. The homogeneity of the mixture in any cross-section at the location of the sampling probe shall not vary by more than ±2 percent from the average of the values obtained for at least five points located at equal intervals on the diameter of the gas stream. For particulate and particle emissions sampling, a dilution tunnel shall be used which:






(a)


shall consist of a straight tube of electrically-conductive material, which shall be earthed;










(b)


shall be small enough in diameter to cause turbulent flow (Reynolds number ≥ 4 000) and of sufficient length to cause complete mixing of the exhaust and dilution air;










(c)


shall be at least 200 mm in diameter;










(d)


may be insulated.




1.3.4.   Suction device
This device may have a range of fixed speeds to ensure sufficient flow to prevent any water condensation. This result is generally obtained if the flow is either:






(a)


twice the maximum flow of exhaust gas produced by accelerations of the driving cycle; or










(b)


sufficient to ensure that the CO2 concentration in the dilute exhaust sample bag is less than 3 percent by volume for petrol and diesel, less than 2,2 percent by volume for LPG and less than 1,5 percent by volume for NG/biomethane.




1.3.5.   Volume measurement in the primary dilution system
The method for measuring total dilute exhaust volume incorporated in the constant volume sampler shall be such that measurement is accurate to ± 2 percent under all operating conditions. If the device cannot compensate for variations in the temperature of the mixture of exhaust gases and dilution air at the measuring point, a heat exchanger shall be used to maintain the temperature to within ± 6 K of the specified operating temperature. If necessary, some form of protection for the volume measuring device may be used, e.g. a cyclone separator, bulk stream filter, etc. A temperature sensor shall be installed immediately before the volume measuring device. This sensor shall have an accuracy and a precision of ± 1 K and a response time of 0,1 s at 62 percent of a given temperature variation (value measured in silicone oil). The difference from atmospheric pressure shall be measured upstream and, if necessary, downstream from the volume measuring device. The pressure measurements shall have a precision and an accuracy of ± 0,4 kPa during the test.
1.4.   Recommended system descriptions
Figure Ap 4-1 and Figure Ap 4-2 are schematic drawings of two types of recommended exhaust dilution systems that meet the requirements of this Annex. Since various configurations can produce accurate results, exact conformity with these figures is not essential. Additional components such as instruments, valves, solenoids and switches may be used to provide additional information and coordinate the functions of the component system.
1.4.1.   Full-flow dilution system with positive displacement pump

Figure Ap4-1


Positive displacement pump dilution system






The positive displacement pump (PDP) full-flow dilution system satisfies the requirements of this Annex by metering the flow of gas through the pump at constant temperature and pressure. The total volume is measured by counting the revolutions of the calibrated positive displacement pump. The proportional sample is achieved by sampling with pump, flow meter and flow control valve at a constant flow rate. The collecting equipment consists of:






1.4.1.1.


A filter (refer to DAF in Figure Ap 4-1) for the dilution air shall be installed, which can be preheated if necessary. This filter shall consist of the following filters in sequence: an optional activated charcoal filter (inlet side) and a high efficiency particulate air (HEPA) filter (outlet side). It is recommended that an additional coarse particle filter is situated before the HEPA filter and after the charcoal filter, if used. The purpose of the charcoal filter is to reduce and stabilise the hydrocarbon concentrations of ambient emissions in the dilution air;










1.4.1.2.


A transfer tube (TT) by which vehicle exhaust is admitted into a dilution tunnel (DT) in which the exhaust gas and dilution air are mixed homogeneously;










1.4.1.3.


The positive displacement pump (PDP), producing a constant-volume flow of the air/exhaust-gas mixture. The PDP revolutions, together with associated temperature and pressure measurement, are used to determine the flow rate;










1.4.1.4.


A heat exchanger (HE) of a capacity sufficient to ensure that throughout the test the temperature of the air/exhaust-gas mixture measured at a point immediately upstream of the positive displacement pump is within 6 K of the average operating temperature during the test. This device shall not affect the pollutant concentrations of diluted gases taken off afterwards for analysis.










1.4.1.5.


A mixing chamber (MC) in which exhaust gas and air are mixed homogeneously and which may be located close to the vehicle so that the length of the transfer tube (TT) is minimised.




1.4.2.   Full-flow dilution system with critical-flow venturi

Figure Ap4-2


Critical-flow venturi dilution system






The use of a critical-flow venturi (CFV) for the full-flow dilution system is based on the principles of flow mechanics for critical flow. The variable mixture flow rate of dilution and exhaust gas is maintained at sonic velocity which is directly proportional to the square root of the gas temperature. Flow is continually monitored, computed and integrated throughout the test. The use of an additional critical-flow sampling venturi ensures the proportionality of the gas samples taken from the dilution tunnel. As pressure and temperature are both equal at the two venturi inlets, the volume of the gas flow diverted for sampling is proportional to the total volume of diluted exhaust-gas mixture produced, and thus the requirements of this Annex are met. The collecting equipment consists of:






1.4.2.1.


A filter (DAF) for the dilution air which can be preheated if necessary. This filter shall consist of the following filters in sequence: an optional activated charcoal filter (inlet side) and a high efficiency particulate air (HEPA) filter (outlet side). It is recommended that an additional coarse particle filter is situated before the HEPA filter and after the charcoal filter, if used. The purpose of the charcoal filter is to reduce and stabilise the hydrocarbon concentrations of ambient emissions in the dilution air;










1.4.2.2.


A mixing chamber (MC) in which exhaust gas and air are mixed homogeneously and which may be located close to the vehicle so that the length of the transfer tube (TT) is minimised;










1.4.2.3.


A dilution tunnel (DT) from which particulates and particles are sampled;










1.4.2.4.


Some form of protection for the measurement system may be used, e.g. a cyclone separator, bulk stream filter, etc.;










1.4.2.5.


A measuring critical-flow venturi tube (CFV) to measure the flow volume of the diluted exhaust gas;










1.4.2.6.


A blower (BL) of sufficient capacity to handle the total volume of diluted exhaust gas.




2.   CVS calibration procedure

2.1.   General requirements
The CVS system shall be calibrated by using an accurate flow-meter and a restricting device. The flow through the system shall be measured at various pressure readings and the control parameters of the system measured and related to the flows. The flow-meter shall be dynamic and suitable for the high flow-rate encountered in CVS testing. The device shall be of certified accuracy traceable to an approved national or international standard.
2.1.1.   Various types of flow-meter may be used, e.g. calibrated venturi, laminar flow-meter, calibrated turbine-meter, provided that they are dynamic measurement systems and can meet the requirements of point 1.3.5. of this Appendix.
2.1.2.   The following points give details of methods of calibrating PDP and CFV units, using a laminar flow-meter which gives the required accuracy, together with a statistical check on the calibration validity.
2.2.   Calibration of the positive displacement pump (PDP)
2.2.1.   The following calibration procedure outlines the equipment, the test configuration and the various parameters that are measured to establish the flow-rate of the CVS pump. All the parameters relating to the pump are simultaneously measured with the parameters relating to the flow-meter which is connected in series with the pump. The calculated flow rate (given in m3/min at pump inlet, absolute pressure and temperature) can then be plotted against a correlation function that is the value of a specific combination of pump parameters. The linear equation that relates the pump flow and the correlation function is then determined. If a CVS has a multiple speed drive, a calibration shall be performed for each range used.
2.2.2.   This calibration procedure is based on the measurement of the absolute values of the pump and flow-meter parameters that relate to the flow rate at each point. Three conditions shall be maintained to ensure the accuracy and integrity of the calibration curve:






2.2.2.1.


The pump pressures shall be measured at tappings on the pump rather than at the external piping on the pump inlet and outlet. Pressure taps that are mounted at the top centre and bottom centre of the pump drive head plate are exposed to the actual pump cavity pressures and therefore reflect the absolute pressure differentials;










2.2.2.2.


Temperature stability shall be maintained during the calibration. The laminar flow-meter is sensitive to inlet temperature oscillations which cause the data points to be scattered. Gradual changes of ± 1 K in temperature are acceptable as long as they occur over a period of several minutes;










2.2.2.3.


All connections between the flow-meter and the CVS pump shall be free of any leakage.




2.2.3.   During an exhaust emission test, the measurement of these same pump parameters enables the user to calculate the flow rate from the calibration equation.
2.2.4.   Figure Ap 4-3 of this Appendix shows one possible test set-up. Variations are permissible, provided that the technical service approves them as being of comparable accuracy. If the set-up shown in Figure Ap 4-3 is used, the following data shall be found within the limits of precision given:






 


Barometric pressure (corrected) (Pb) ± 0,03 kPa










 


Ambient temperature (T) ± 0,2 K










 


Air temperature at LFE (ETI) ± 0,15 K










 


Pressure depression upstream of LFE (EPI) ± 0,01 kPa










 


Pressure drop across the LFE matrix (EDP) ± 0,0015 kPa










 


Air temperature at CVS pump inlet (PTI) ± 0,2 K










 


Air temperature at CVS pump outlet (PTO) ± 0,2 K










 


Pressure depression at CVS pump inlet (PPI) ± 0,22 kPa










 


Pressure head at CVS pump outlet (PPO) ± 0,22 kPa










 


Pump revolutions during test period (n) ± 1 min-1











 


Elapsed time for period (minimum 250 s) (t) ± 0,1 s





Figure Ap4-3


PDP calibration configuration






2.2.5.   After the system has been connected as shown in Figure Ap 4-3, set the variable restrictor in the wide-open position and run the CVS pump for 20 minutes before starting the calibration.
2.2.6.   Reset the restrictor valve to a more restricted condition in an increment of pump inlet depression (about 1 kPa) that will yield a minimum of six data points for the total calibration. Allow the system to stabilise for three minutes and repeat the data acquisition.
2.2.7.   The air flow rate (Qs) at each test point is calculated in standard m3/min from the flow-meter data using the manufacturer’s prescribed method.
2.2.8.   The air flow-rate is then converted to pump flow (V0) in m3/rev at absolute pump inlet temperature and pressure.

Equation Ap 4-1:






where:

V0
= pump flow rate at Tp and Pp (m3/rev);

Qs
= air flow at 101,33 kPa and 273,2 K (m3/min);

Tp
= pump inlet temperature (K);

Pp
= absolute pump inlet pressure (kPa);

n= pump speed (min-1).
2.2.9.   To compensate for the interaction of pump speed pressure variations at the pump and the pump slip rate, the correlation function (x0) between the pump speed (n), the pressure differential from pump inlet to pump outlet, and the absolute pump outlet pressure is calculated as follows:

Equation Ap 4-2:






where:

x0
= correlation function;

ΔPp
= pressure differential from pump inlet to pump outlet (kPa);

Pe
= absolute outlet pressure (PPO + Pb) (kPa).








2.2.9.1.


A linear least-square fit is performed to generate the calibration equations which have the formula:

Equation Ap 4-3:











D0, M, A and B are the slope-intercept constants describing the lines.




2.2.10.   A CVS system that has multiple speeds shall be calibrated on each speed used. The calibration curves generated for the ranges shall be approximately parallel and the intercept values (D0) shall increase as the pump flow range decreases.
2.2.11   If the calibration has been performed carefully, the calculated values from the equation will be within 0.5 percent of the measured value of V0.Values of M will vary from one pump to another. Calibration is performed at pump start-up and after major maintenance.
2.3.   Calibration of the critical-flow venturi (CFV)
2.3.1.   Calibration of the CFV is based on the flow equation for a critical-flow venturi:

Equation Ap 4-4:






where:

Qs
= flow;

Kv
= calibration coefficient;

P= absolute pressure (kPa);

T= absolute temperature (K).
Gas flow is a function of inlet pressure and temperature. The calibration procedure described in points 2.3.2. to 2.3.7. shall establish the value of the calibration coefficient at measured values of pressure, temperature and air flow.
2.3.2.   The manufacturer’s recommended procedure shall be followed for calibrating electronic portions of the CFV.
2.3.3.   Measurements for flow calibration of the critical-flow venturi are required and the following data shall be found within the limits of precision given:






 


Barometric pressure (corrected) (Pb) ± 0,03 kPa










 


LFE air temperature, flow-meter (ETI) ± 0,15 K










 


Pressure depression upstream of LFE (EPI) ± 0,01 kPa










 


Pressure drop across (EDP) LFE matrix ± 0,0015 kPa










 


Air flow (Qs) ± 0,5 percent










 


CFV inlet depression (PPI) ± 0,02 kPa










 


Temperature at venturi inlet (Tv) ± 0,2 K.




2.3.4.   The equipment shall be set up as shown in Figure Ap 4-4 and checked for leaks. Any leaks between the flow-measuring device and the critical-flow venturi will seriously affect the accuracy of the calibration.

Figure Ap4-4


CFV calibration configuration






2.3.5.   The variable-flow restrictor shall be set to the open position, the blower shall be started and the system stabilised. Data from all instruments shall be recorded.
2.3.6.   The flow restrictor shall be varied and at least eight readings shall be taken across the critical flow range of the venturi.
2.3.7.   The data recorded during the calibration shall be used in the following calculations. The air flow-rate (Qs) at each test point is calculated from the flow-meter data using the manufacturer’s prescribed method. Calculate values of the calibration coefficient (Kv) for each test point:

Equation Ap 4-5:






where:

Qs
= flow-rate in m3/min at 273,2 K and 101,3 kPa;

Tv
= temperature at the venturi inlet (K);

Pv
= absolute pressure at the venturi inlet (kPa).
Plot Kv as a function of venturi inlet pressure. For sonic flow, Kv will have a relatively constant value. As pressure decreases (vacuum increases), the venturi becomes unchoked and Kv decreases. The resultant Kv changes are not permissible. For a minimum of eight points in the critical region, calculate an average Kv and the standard deviation. If the standard deviation exceeds 0,3 percent of the average Kv, take corrective action.
3.   System verification procedure

3.1.   General requirements
The total accuracy of the CVS sampling system and analytical system shall be determined by introducing a known mass of a pollutant gas into the system while it is being operated as if during a normal test and then analysing and calculating the pollutant mass according to the formula in point 4, except that the density of propane shall be taken as 1,967 grams per litre at standard conditions. The two techniques described in points 3.2. and 3.3. are known to give sufficient accuracy. The maximum permissible deviation between the quantity of gas introduced and the quantity of gas measured is 5 percent.
3.2.   CFO method
3.2.1.   Metering a constant flow of pure gas (CO or C3H8) using a critical-flow orifice device
3.2.2.   A known quantity of pure gas (CO or C3H8) is fed into the CVS system through the calibrated critical orifice. If the inlet pressure is high enough, the flow-rate (q), which is adjusted by means of the critical-flow orifice, is independent of orifice outlet pressure (critical flow). If deviations exceeding 5 percent occur, the cause of the malfunction shall be determined and corrected. The CVS system is operated as in an exhaust emission test for about five to ten minutes. The gas collected in the sampling bag is analysed by the usual equipment and the results compared to the concentration of the gas samples which was known beforehand.
3.3.   Gravimetric method
3.3.1.   Metering a limited quantity of pure gas (CO or C3H8) by means of a gravimetric technique
3.3.2.   The following gravimetric procedure may be used to verify the CVS system. The weight of a small cylinder filled with either carbon monoxide or propane is determined with a precision of ± 0,01 g. For about five to ten minutes, the CVS system is operated as in a normal exhaust emission test, while CO or propane is injected into the system. The quantity of pure gas involved is determined by means of differential weighing. The gas accumulated in the bag is analysed using the equipment normally used for exhaust-gas analysis. The results are then compared to the concentration figures computed previously.

ECE R40-based test cycle tolerances




K = Declutching
The speed tolerance (± 1 km/h) and the time tolerance (± 1 sec) shall be combined geometrically for each common point shown opposite.
PM = Neutral
R = Idling
4.   Generic applicable ECE R40 and R47 test cycle tolerances









4.1.


A tolerance of 1 km/h over or under the theoretical speed shall be allowed during all phases of the test cycle. Speed tolerances greater than those prescribed shall be accepted during phase changes provided that the tolerances are not exceeded for more than 0,5 second on any occasion, without prejudice to the provisions of points 4.3. and 4.4. The time tolerance shall be + 0,5 sec.












4.2.


The distance driven during the cycle shall be measured to (0 / + 2) percent.












4.3.


If the acceleration capability of the L-category vehicle is not sufficient to carry out the acceleration phases within the prescribed limits of tolerances or the prescribed maximum vehicle speed in the individual cycles cannot be achieved owing to a lack of propulsion power, the vehicle shall be driven with the throttle fully open until the speed prescribed for the cycle is reached and the cycle shall be carried on normally.












4.4.


If the period of deceleration is shorter than that prescribed for the corresponding phase, the timing of the theoretical cycle shall be restored by a constant speed or idling period merging into the subsequent constant speed or idling operation. In such cases, point 4.1 shall not apply.




5.   Sampling of the exhaust flow of the vehicle in the ECE R40 and R47 test cycles

5.1.   Check of back-pressure from sampling device
During the preliminary tests, a check shall be made to ensure that the back-pressure set up by the sampling device is equal to the atmospheric pressure to within ± 1 230 Pa.
5.2.   Sampling shall start as of t=0 just before cranking and starting-up of the combustion engine if that engine makes part of the propulsion type.
5.3.   The combustion engine shall be started up by means of the devices provided for that purpose — the choke, the starter valve, etc. — in accordance with the manufacturer’s instructions.
5.4.   The sampling bags shall be hermetically closed as soon as filling is completed.
5.5.   At the end of the test cycle, the system for collecting dilute exhaust mixture and dilution air shall be closed and the gases produced by the engine shall be released into the atmosphere.
6.   Gearshift procedures









6.1.


The ECE R47 test shall be conducted using the gearshift procedure set out in point 2.3 of UNECE regulation No 47.












6.2.


The ECE R40 test shall be conducted using the gearshift procedure set out in point 2.3 of UNECE regulation No 40.

(4)   World Harmonised Motorcycle Test Cycle (WMTC) stage 3 (Revised WMTC)

1.   Description of the WMTC stage 3 test cycle for L3e, L4e, L5e-A, L7e-A, L7e-B and L7e-C (sub-)category vehicles

The WMTC stage 3 to be used on the chassis dynamometer shall be as depicted in the following graph for (sub-)category L3e, L4e, L5e-A, L7e-A, L7e-B and L7e-C vehicles:

Figure Ap6-9


WMTC stage 3 for L3e, L4e, L5e-A, L7e-A, L7e-B and L7e-C category vehicles




Vehicle speed parts 1, 2 & 3
Vehicle speed parts 1, 2 & 3 reduced
The ‘revised WMTC’ also referred to as ‘WMTC stage 3’ as shown in Figure Ap 6-9 is applicable for L3e, L4e, L5e-A, L7e-A, L7e-B and L7e-C vehicles and the vehicle speed trace of WMTC stage 3 is equivalent to WMTC stages 1 and 2. The WMTC stage 3 lasts 1 800 seconds and consists of two parts for vehicles with a low maximum design vehicle speed and three parts for the other L-category vehicles to be carried out without interruption if allowed by maximum vehicle speed limitation. The characteristic driving conditions (idling, acceleration, steady speed, deceleration, etc.) of WMTC stage 3 are laid down in chapter 3, which sets out the detailed vehicle speed trace of the WMTC stage 2.
2.   Description of the WMTC stage 3 for L1e-A, L1e-B, L2e, L5e-B, L6e-A and L6e-B (sub-)category vehicles

The WMTC stage 3 to be used on the chassis dynamometer shall be a depicted in the following graph for (sub-)category L1e-A, L1e-B, L2e, L6e-A and L6e-B vehicles with a low maximum vehicle design speed:

Figure Ap6-10


WMTC stage 3 for L1e-A, L1e-B, L2e, L5e-B, L6e-A and L6e-B vehicles. The truncated vehicle speed trace limited to 25 km/h is applicable for L1e-A and L1e-B vehicles with a limited maximum design vehicle speed of 25 km/h




Vehicle class 1 45 km/h limit
Vehicle class 1 25 km/h limit
2.1   The cold and warm vehicle speed traces are identical.
3.   Description of the WMTC stage 3 for L1e-A, L1e-B, L2e, L5e-B, L6e-A and L6e-B (sub-)category vehicles


Figure Ap6-11


WMTC stage 3 for L1e-A, L1e-B, L2e, L5e-B, L6e-A and L6e-B (sub-)category vehicles. The truncated vehicle speed trace limited to 25 km/h is applicable for L1e-A and L1e-B vehicles with a limited maximum vehicle design speed of 25 km/h




Vehicle class 1 45 km/h limit
Vehicle class 1 45 km/h limit
3.1.   The vehicle speed trace WMTC stage 3 shown in Figure Ap 6-10 is applicable for L1e-A, L1e-B, L2e, L5e-B, L6e-A and L6e-B (sub-)category vehicles and is equivalent to the vehicle speed trace WMTC stages 1 and 2, part 1 for class 1 vehicles, driven once cold followed by the same vehicle speed driven with a warmed-up propulsion. The WMTC stage 3 for L1e-A, L1e-B, L2e, L5e-B, L6e-A and L6e-B (sub-)category vehicles lasts 1 200 seconds and consists of two equivalent parts to be carried out without interruption.
3.2.   The characteristic driving conditions (idling, acceleration, steady speed, deceleration, etc.) of WMTC stage 3 for L1e-A, L1e-B, L2e, L5e-B, L6e-A and L6e-B vehicles are set out in the following points and tables.

4.3.


When the running resistance is verified in accordance with point 5.2.2.3.2., the test can be executed at vj ± 5 km/h, provided that the coast-down time accuracy referred to in point 4.5.7. of Annex II is ensured.




5.   Measurement of coast-down time









5.1.


After a warm-up period, the vehicle shall be accelerated to the coast-down starting speed, at which point the coast-down measurement procedure shall be started.

Equation Ap7-6:






where:

mref
= reference mass (kg);

Δv= vehicle speed deviation (km/h);

Δt= calculated coast down time difference (s);












6.1.2.


The running resistance force Fj shall be corrected in accordance with point 6.2.




6.2.   Running resistance curve fitting
The running resistance force, F, shall be calculated as follows:








6.2.1.

Appendix 9

Explanatory note on the gearshift procedure for a type I test

0.   Introduction

This explanatory note explains matters specified or described in this Regulation, including its Annexes or Appendices, and matters related thereto with regard to the gearshift procedure.
1.   Approach









1.1.


The development of the gearshift procedure was based on an analysis of the gearshift points in the in-use data. In order to establish generalised correlations between technical specifications of the vehicles and gearshift speeds, the engine speeds were normalised to the utilisable band between rated speed and idling speed.












1.2.


In a second step, the end speeds (vehicle speed as well as normalised engine speed) for upshifts and downshifts were determined and recorded in a separate table. The averages of these speeds for each gear and vehicle were calculated and correlated with the vehicles’ technical specifications.












1.3.


The results of these analyses and calculations can be summarised as follows:






(a)


the gearshift behaviour is engine-speed-related rather than vehicle-speed-related;










(b)


the best correlation between gearshift speeds and technical data was found for normalised engine speeds and the power-to-mass ratio (maximum continuous rated power/(mass in running order + 75 kg));










(c)


the residual variations cannot be explained by other technical data or by different drive train ratios. They are most probably due to differences in traffic conditions and individual driver behaviour;










(d)


the best approximation between gearshift speeds and power-to-mass ratio was found for exponential functions;










(e)


the gearshift mathematical function for the first gear is significantly lower than for all other gears;










(f)


the gearshift speeds for all other gears can be approximated by one common mathematical function;










(g)


no differences were found between five-speed and six-speed gearboxes;










(h)


gearshift behaviour in Japan is significantly different from the equal-type gearshift behaviour in the European Union (EU) and in the United States of America (USA).
















1.4.


In order to find a balanced compromise between the three regions, a new approximation function for normalised upshift speeds versus power-to-mass ratio was calculated as a weighted average of the EU/USA curve (with 2/3 weighting) and the Japanese curve (with 1/3 weighting), resulting in the following equations for normalised engine upshift speeds:






 



Equation Ap9-1: Normalised upshift speed in 1st gear (gear 1)















 



Equation Ap9-2: Normalised upshift speed in gears > 1













2.   Calculation example

2.1   Figure Ap 9-1 shows an example of gearshift use for a small vehicle:






(a)


the lines in bold show the gear use for acceleration phases;










(b)


the dotted lines show the downshift points for deceleration phases;










(c)


in the cruising phases, the whole speed range between downshift speed and upshift speed may be used.




2.2   Where vehicle speed increases gradually during cruise phases, upshift speeds (v1—2, v2—3and vi—i+1) in km/h may be calculated using the following equations:






 



Equation Ap9-3:
















 



Equation Ap9-4:
















 



Equation Ap9-5:

In order to allow the technical service more flexibility and to ensure driveability, the gearshift regression functions should be considered as lower limits. Higher engine speeds are permitted in any cycle phase.
3.   Phase indicators

3.1   In order to avoid different interpretations in the application of the gearshift equations and thus to improve the comparability of the test, fixed-phase indicators are assigned to the speed pattern of the cycles. The specification of the phase indicators is based on the definition from the Japan Automobile Research Institute (JARI) of the four driving modes as shown in the following table:

Table Ap9-1


Definition of driving modes







4 modes


Definition




Idle mode


vehicle speed < 5 km/h and
-0,5 km/h/s (-0,139 m/s2) < acceleration < 0,5 km/h/s (0,139 m/s2)




Acceleration mode


acceleration > 0,5 km/h/s (0,139 m/s2)




Deceleration mode


acceleration < - 0,5 km/h/s (- 0,139 m/s2)




Cruise mode


vehicle speed ≥ 5 km/h and
-0,5 km/h/s (-0,139 m/s2) < acceleration < 0,5 km/h/s (0,139 m/s2)




3.2   The indicators were then modified in order to avoid frequent changes during relatively homogeneous cycle parts and thus improve driveability. Figure Ap9-2 shows an example from cycle part 1.

4.   Calculation example









4.1.


An example of input data necessary for the calculation of shift speeds is shown in Table Ap 9-2. The upshift speeds for acceleration phases for first gear and higher gears are calculated using Equations 9-1 and 9-2. The denormalisation of engine speeds can be performed using the equation 

.












4.2.


The downshift speeds for deceleration phases can be calculated using Equations 9-3 and 9-4. The ndv values in Table Ap 9-2 can be used as gear ratios. These values can also be used to calculate the corresponding vehicle speeds (

. The results are shown in Tables Ap9-3 and Ap9-4.












4.3.


Additional analyses and calculations were conducted to investigate whether these gearshift algorithms could be simplified and, in particular, whether engine shift speeds could be replaced by vehicle shift speeds. The analysis showed that vehicle speeds could not be brought in line with the gearshift behaviour of the in-use data.

Appendix 12

Type I test procedure for L-category vehicles fuelled with LPG, NG/biomethane, flex fuel H2NG or hydrogen

1.   Introduction









1.1.


This Appendix describes the special requirements as regards the testing of LPG, NG/biomethane, H2NG or hydrogen gas for the approval of alternative fuel vehicles that run on those fuels or can run on petrol, LPG, NG/biomethane, H2NG or hydrogen.












1.2.


The composition of these gaseous fuels, as sold on the market, can vary greatly and fuelling systems must adapt their fuelling rates accordingly. To demonstrate this adaptability, the parent vehicle equipped with a representative LPG, NG/biomethane or H2NG fuel system shall be tested in type I tests on two extreme reference fuels.












1.3.


The requirements of this Appendix as regards hydrogen shall apply only to vehicles using hydrogen as a combustion fuel and not to those equipped with a fuel cell operating on hydrogen.




2.   Granting of type-approval for an L-category vehicle equipped with a gaseous fuel system

Type-approval is granted subject to the following requirements:
2.1.   Exhaust emissions approval of a vehicle equipped with a gaseous fuel system
It shall be demonstrated that the parent vehicle equipped with a representative LPG, NG/biomethane, H2NG or hydrogen fuel system can adapt to any fuel composition that may appear on the market and comply with the following:






2.1.1.


In the case of LPG there are variations in C3/C4 composition (test fuel requirement A and B) and therefore the parent vehicle shall be tested on reference fuels A and B referred to in Appendix 2;










2.1.2.


In the case of NG/biomethane there are generally two types of fuel, high calorific fuel (G20) and low calorific fuel (G25), but with a significant spread within both ranges; they differ significantly in Wobbe index. These variations are reflected in the reference fuels. The parent vehicle shall be tested on both reference fuels referred to in Appendix 2;










2.1.3.


In the case of a flex fuel H2NG vehicle, the composition range may vary from 0 % hydrogen (L-gas) to a maximum percentage of hydrogen within the mixture (H-gas), as specified by the manufacturer. It shall be demonstrated that the parent vehicle can adapt to any percentage within the range specified by the manufacturer and the vehicle shall be tested in the type I test on 100 % H-gas and 100 % L-gas. It shall also be demonstrated that it can adapt to any NG/biomethane composition that may appear on the market, regardless of the percentage of hydrogen in the mixture.










2.1.4.


For vehicles equipped with hydrogen fuel systems, compliance shall be tested on the single hydrogen reference fuel referred to in Appendix 2.










2.1.5.


If the transition from one fuel to another is in practice aided through the use of a switch, this switch shall not be used during type-approval. In such cases, at the manufacturer’s request and with the agreement of the technical service, the pre-conditioning cycle referred in point 5.2.4 of Annex II may be extended.










2.1.6.


The ratio of emission results ‘r’ shall be determined for each pollutant as shown in Table Ap12-1 for LPG, NG/biomethane and H2NG vehicles.






2.1.6.1.


In the case of LPG and NG/biomethane vehicles, the ratios of emission results ‘r’ shall be determined for each pollutant as follows:

2.2.   Exhaust emissions approval of a member of the propulsion family
For the type-approval of mono-fuel gas vehicles and bi-fuel vehicles operating in gas mode, fuelled by LPG, NG/biomethane, H2NG or hydrogen, as a member of the propulsion family in Annex XI, a type I test shall be performed with one gaseous reference fuel. For LPG, NG/biomethane and H2NG vehicles, this reference fuel may be either of the reference fuels in Appendix 2. The gas-fuelled vehicle is considered to comply if the following requirements are met:






2.2.1.


The test vehicle shall comply with the definition of a propulsion family member in Annex XI.










2.2.2.


If the test fuel requirement is reference fuel A for LPG or G20 for NG/biomethane, the emission result shall be multiplied by the relevant factor ‘r’ if r > 1; if r < 1, no correction is needed.










2.2.3.


If the test fuel requirement is reference fuel B for LPG or G25 for NG/biomethane, the emission result shall be divided by the relevant factor ‘r’ if r < 1; if r > 1, no correction is needed.










2.2.4.


At the manufacturer’s request, the type I test may be performed on both reference fuels, so that no correction is needed.










2.2.5.


The parent vehicle shall comply with the emission limits for the relevant category set out in Annex VI(A) to Regulation (EU) No 168/2013 and for both measured and calculated emissions.










2.2.6.


If repeated tests are conducted on the same engine, an average shall first be taken of the results on reference fuel G20, or A, and those on reference fuel G25, or B; the ‘r’ factor shall then be calculated from these averages.










2.2.7.


For the type-approval of a flex fuel H2NG vehicle as a member of a family, two type I tests shall be performed, the first test with 100 % of either G20 or G25, and the second test with the mixture of hydrogen and the same NG/biomethane fuel used during the first test, with the maximum hydrogen percentage specified by the manufacturer.






2.2.7.1.


If the NG/biomethane fuel is the reference fuel G20, the emission result for each pollutant shall be multiplied by the relevant factors (r1 for the first test and r2 for the second test) in point 2.1.6. if the relevant factor > 1; if the correspondent relevant factor < 1, no correction is needed.










2.2.7.2.


If the NG/biomethane fuel is the reference fuel G25, the emission result for each pollutant shall be divided by the corresponding relevant factor (r1 for the first test and r2 for the second test) calculated in accordance with point 2.1.6., if this is < 1; if the corresponding relevant factor > 1, no correction is needed.










2.2.7.3.


At the manufacturer’s request, the type I test shall be conducted with the four possible combinations of reference fuels, in accordance with point 2.1.6., so that no correction is needed.










2.2.7.4.


If repeated tests are carried out on the same engine, an average shall first be taken of the results on reference fuel G20, or H2G20, and those on reference fuel G25, or H2G25 with the maximum hydrogen percentage specified by the manufacturer; the ‘r1’ and ‘r2’ factors shall then be calculated from these averages.














2.2.8.


During the type I test, the vehicle shall use only petrol for a maximum of 60 consecutive seconds directly after engine crank and start when operating in gas-fuelling mode.








Appendix 13

Type I test procedure for L-category vehicles equipped with a periodically regenerating system

1.   Introduction

This Appendix contains specific provisions regarding the type-approval of vehicles equipped with a periodically regenerating system.
2.   Scope of the type-approval for vehicles with a periodically regenerating system as regards type I tests

2.1.   L-category vehicles falling within the scope of Regulation (EU) No 168/2013 that are equipped with periodically regenerating systems shall comply with the requirements in this Appendix.
2.2.   Instead of carrying out the test procedures in the following point, a fixed Ki value of 1,05 may be used if the technical service sees no reason why this value could be exceeded and after approval of the approval authority.
2.3.   During cycles where regeneration occurs, emission standards can be exceeded. If a regeneration of an anti-pollution device occurs at least once per Type I test and that has already regenerated at least once during the vehicle preparation cycle, it will be considered as a continuously regenerating system which does not require a special test procedure.
3.   Test procedure

The vehicle may be equipped with a switch capable of preventing or permitting the regeneration process provided that its operation has no effect on original engine calibration. This switch shall be used for the purpose of preventing regeneration only during loading of the regeneration system and during the pre-conditioning cycles. However, it shall not be used during the measurement of emissions in the regeneration phase; rather, the emission test shall be carried out with the unchanged original equipment manufacturer’s powertrain control unit / engine control unit / drive train control unit if applicable and powertrain software.
3.1.   Measurement of carbon dioxide emission and fuel consumption between two cycles where regenerative phases occur.
3.1.1.   The average of carbon dioxide emission and fuel consumption between regeneration phases and during loading of the regenerative device shall be determined from the arithmetic mean of several approximately equidistant (if more than two) type I operating cycles.
As an alternative, the manufacturer may provide data to show that carbon dioxide emissions and fuel consumption remain constant (+4 percent) between regeneration phases. In this case, the carbon dioxide emissions and fuel consumption measured during the regular type I test may be used. In any other case, emissions shall be measured for at least two type I operating cycles: one immediately after regeneration (before new loading) and one as immediately as possible before a regeneration phase. All emissions measurements and calculations shall be carried out in accordance with Annex II. Average emissions for a single regenerative system shall be determined in accordance with point 3.3 and for multiple regeneration systems in accordance with point 3.4.
3.1.2.   The loading process and Ki determination shall be carried out on a chassis dynamometer during the type I operating cycles. These cycles may be run continuously (i.e. without the need to switch the engine off between cycles). After any number of completed cycles, the vehicle may be removed from the chassis dynamometer and the test continued at a later time.
3.1.3.   The number of cycles (D) between two cycles in which regeneration phases occur, the number of cycles over which emissions measurements are taken (n) and each emissions measurement (M’sij) shall be reported according to the template of the test report referred to in Article 32(1) of Regulation (EU0 No 168/2013.
3.2.   Measurement of carbon dioxide emissions and fuel consumption during regeneration
3.2.1.   If necessary, the vehicle may be prepared for the emissions test during a regeneration phase using the preparation cycles in Appendix 6.
3.2.2.   The test and vehicle conditions for the type I test described in Annex II apply before the first valid emission test is carried out.
3.2.3.   Regeneration shall not occur during the preparation of the vehicle. This may be ensured by one of the following methods:






3.2.3.1.


a ‘dummy’ regenerating system or partial system may be fitted for the pre-conditioning cycles;










3.2.3.2.


any other method agreed between the manufacturer and the approval authority.




3.2.4.   A cold-start exhaust emission test including a regeneration process shall be carried out in accordance with the applicable type I operating cycle.
3.2.5.   If the regeneration process requires more than one operating cycle, subsequent test cycle(s) shall be driven immediately, without switching the engine off, until complete regeneration has been achieved (each cycle shall be completed). The time necessary to set up a new test shall be as short as possible (e.g. as required to change a particulate matter filter on the analysing equipment). The engine shall be switched off during this period.
3.2.6.   The emission values, including pollutant and carbon dioxide emission values, and fuel consumption during regeneration (Mri) shall be calculated in accordance with Annex II and point 3.3. The number of operating cycles (d) measured for complete regeneration shall be recorded.
3.3.   Calculation of the combined exhaust emissions of a single regenerative system:

3.4.1.   Extension of approval for a multiple periodic regeneration system








3.4.1.1.


If the technical parameters or the regeneration strategy of a multiple regeneration system for all events within this combined system are changed, the complete procedure including all regenerative devices shall be performed by measurements to update the multiple Ki – factor.












3.4.1.2.


If a single device of the multiple regeneration system is changed only in strategy parameters (i.e. such as ‘D’ or ‘d’ for DPF) and the manufacturer can provide the technical service with plausible technical data and information demonstrating that:






(a)


there is no detectable interaction with the other device(s) of the system; and










(b)


the important parameters (i.e. construction, working principle, volume, location, etc.) are identical,




the necessary update procedure for ki may be simplified.
In such cases, where agreed between the manufacturer and the technical service, only a single event of sampling/storage and regeneration shall be performed and the test results (‘Msi
                        ’, ‘Mri
                        ’), in combination with the changed parameters (‘D’ or ‘d’), may be introduced into the relevant formula(e) to update the multiple Ki - factor in mathematically by substituting the existing basic Ki - factor formula(e).

3.6.   The type II emission test shall be conducted immediately after the type I emission test. In any event, the engine shall be warmed up until all coolant and lubricant temperatures and lubricant pressure have reached equilibrium at operational levels.
3.7.   The exhaust outlets shall be provided with an air-tight extension, so that the sample probe used to collect exhaust gases may be inserted at least 60 cm into the exhaust outlet without increasing the back pressure of more than 125 mm H2O and without disturbing operation of the vehicle. This extension shall be so shaped as to avoid any appreciable dilution of exhaust gases in the air at the location of the sample probe. Where a vehicle is equipped with an exhaust system with multiple outlets, either these shall be joined to a common pipe or the carbon monoxide content shall be collected from each of them and an arithmetical average taken.
3.8.   The emission test equipment and analysers to perform the type II testing shall be regularly calibrated and maintained. A flame ionisation detection or NDIR analyser may be used for measuring hydrocarbons.
3.9.   The vehicles shall be tested with the fuel-consuming engine running.








3.9.1.


The manufacturer shall provide a type II test ‘service mode’ that makes it possible to inspect the vehicle for roadworthiness tests on a running fuel-consuming engine, in order to determine its performance in relation to the data collected. Where this inspection requires a special procedure, this shall be detailed in the service manual (or equivalent media). That special procedure shall not require the use of special equipment other than that provided with the vehicle.

(b) (ii) shall not be applicable for vehicles in the scope of Regulation (EU) No 168/2013. The measured CO value in the Type II test procedure shall be entered on the certificate of conformity;














4.2.4.2.


the maximum content obtained by continuously varying each of the adjustment components in turn while all other components are kept stable shall not exceed the limit value referred to in point 4.2.4.1.

4.3.   The following parameters shall be measured and recorded at normal idling speed and at high idle speed:






(a)


the carbon monoxide (CO) content by volume of the exhaust gases emitted (in vol %);










(b)


the carbon dioxide (CO2) content by volume of the exhaust gases emitted (in vol %);

6.2.   To initiate each free acceleration cycle, the throttle pedal shall be fully depressed quickly and continuously (in less than one second) but not violently, so as to obtain maximum delivery from the fuel pump.
6.3.   During each free acceleration cycle, the engine shall reach cut-off speed or, for vehicles with automatic transmissions, the speed specified by the manufacturer or, if this data is not available, two-thirds of the cut-off speed, before the throttle is released. This could be checked, for instance, by monitoring engine speed or by allowing at least two seconds elapsing between initial throttle depression and release.
6.4.   For vehicles equipped with CVT and automatic clutch, the driven wheels may be lifted from the ground.
For engines with safety limits in the engine control (e.g. max 1 500 rpm without running wheels or without gear), this maximum engine speed shall be reached.
6.5.   The average concentration level of the particulate matter (in m–1) in the exhaust flow (opacity) shall be measured during five free acceleration tests. Opacity means an optical measurement of the density of particulate matter in the exhaust flow of an engine, expressed in m–1;

Appendix 1

Fuel storage permeability test procedure

1.   Scope

1.1.   This requirement shall apply to all L-category vehicles equipped with a non-metallic fuel tank to store liquid, volatile fuel, as applicable for vehicles equipped with a positive ignition combustion engine.
1.2.   Vehicles complying with the requirements set out in Appendix 2 or 3 or vehicles equipped with a compression ignition engine using low volatile fuel shall comply with the requirements of this Appendix only as preconditioning procedure for fuel storage testing referred to in Number C8 of Annex II to Regulation (EU) No 168/2013. The fuel tanks on those vehicles are exempted from the evaporative requirements set out in points 2.1.5, 2.1.6, 2.3. and 2.4.
2.   Fuel tank permeability test

2.1.   Test method
2.1.1.   Test temperature
The fuel tank shall be tested at a temperature of 313,2 ± 2 K (40 ± 2 °C).
2.1.2.   Test fuel
The test fuel to be used shall be the reference fuel set out in Appendix 2 of Annex II. If this test procedure is used only as preconditioning for subsequent fuel storage testing referred to in Number C8 of Annex II to Regulation (EU) No 168/2013, a commercial premium-grade fuel may be used at the choice of the manufacturer and to the satisfaction of the approval authority.
2.1.3.   The tank is filled with the test fuel up to 50 % of its total rated capacity and allowed to rest in the ambient air at a temperature of 313,2 ± 2 K until there is a constant weight loss. That period shall be at least four weeks (pre-storage period). The tank is emptied and then refilled with test fuel to 50 % of its rated capacity.
2.1.4.   The tank is stored under the stabilising conditions at a temperature of 313,2 ± 2 K until its contents are at the test temperature. The tank is then sealed. The pressure rise in the tank during the test may be compensated.
2.1.5.   The weight loss due to diffusion shall be measured during the eight-week test. During that period, a maximum quantity of 20 000 mg may escape from the fuel tank, on average, every 24 hours.
2.1.6.   If the diffusion losses are greater, the fuel loss shall also be determined at a test temperature of 296,2 ± 2 K (23 ± 2 °C), all other conditions being maintained (pre-storage at 313,2 ± 2 K). The loss determined under those conditions shall not exceed 10 000 mg per 24 hours.

2.2.   Metallic tanks are exempted from durability testing.
3.   Preconditioning fuel soak for the fuel tank permeation test

To precondition the fuel tank in the fuel tank permeation test, the following five steps shall be followed:
3.1.   The tank shall be filled with reference fuel specified in Appendix 2 to Annex II, and sealed. The filled tank shall be soaked at an ambient temperature of 301,2 ± 5 K (28 ± 5 °C) for 20 weeks or at 316,2 ± 5 K (43 ± 5 °C) for ten weeks. Alternatively, a shorter period of time at a higher -temperature may be used as soak time if the manufacturer can prove to the approval authority that the hydrocarbon permeation rate has stabilised.
3.2.   The fuel tank’s internal surface area shall be determined in square metres accurate to at least three significant figures. The manufacturer may use less accurate estimates of the surface area if it is ensured that the surface area will not be overestimated.
3.3.   The fuel tank shall be filled with the reference fuel to its nominal capacity.
3.4.   The tank and fuel shall equilibrate to 301,2 ± 5 K (28 ± 5 °C) or 316,2 ± 5 K (43 ± 5 °C) in the case of the alternative short test.
3.5.   The fuel tank shall be sealed using fuel caps and other fittings (excluding petcocks) that can be used to seal openings in a production fuel tank. In cases where openings are not normally sealed on the fuel tank (such as hose-connection fittings and vents in fuel caps), these openings may be sealed using non-permeable fittings such as metal or fluoropolymer plugs.
4.   Fuel tank permeation test procedure

To run the test, the following steps shall be taken for a tank preconditioned as specified in point 3.
4.1.   Weigh the sealed fuel tank and record the weight in mg. This measurement shall be taken within eight hours of filling of the tank with test fuel.
4.2.   The tank shall be placed in a ventilated, temperature-controlled room or enclosure.
4.3.   The test room or enclosure shall be closed and sealed and the test time shall be recorded.
4.4.   The test room or enclosure temperature shall be continuously maintained at 301,2 ± 2 K (28 ± 5 °C) for 14 days. This temperature shall be continuously monitored and recorded.
5.   Fuel tank permeation test result calculation

5.1.   At the end of the soak period, the weight in mg of the sealed fuel tank shall be recorded. Unless the same fuel is used in the preconditioning fuel soak and the permeation test run, weight measurements shall be recorded on five separate days per week of testing. The test is void if a linear plot of tank weight vs. test days for the full soak period for permeation testing yields a linear regression correlation coefficient r2 < 0,8.
5.2.   The weight of the filled fuel tank at the end of the test shall be subtracted from the weight of the filled fuel tank at the beginning of the test.
5.3.   The difference in mass shall be divided by the internal surface area of the fuel tank.
5.4.   The result of the calculation under point 5.3., expressed in mg/m2, shall be divided by the number of test days to calculate the mg/m2/day emission rate and rounded to the same number of decimal places as the emission standard laid down in Part C2 of Annex VI to Regulation (EU) No 168/2013.
5.5.   In cases where permeation rates during a soak period of 14 days are such that the manufacturer considers that period not long enough to be able to measure significant weight changes, the period may be extended by a maximum of 14 additional days. In this case, the test steps in points 4.5 to 4.8 shall be repeated to determine the weight change for the full 28 days.
5.6.   Determination of the deterioration factor when applying the full permeation test procedure
The deterioration factor (DF) shall be determined from any of the following at the choice of the manufacturer:






5.6.1.

A slosh test shall be conducted by filling the non-metallic fuel tank to 40 percent of its capacity with the reference fuel set out in Appendix 2 to Annex II or with a commercial premium-grade fuel at the choice of the manufacturer and to the satisfaction of the approval authority. The fuel tank assembly shall be rocked at a rate of 15 cycles per minute until one million total cycles are reached. An angle deviation of + 15° to – 15° from level shall be used and the slosh test shall be conducted at an ambient temperature of 301,2 ± 5 K (28 ± 5 °C).
6.2.   Final fuel tank durability test results
Following the durability testing, the fuel tank shall be soaked according to the requirements of point 3 to ensure that the permeation rate is stable. The period of slosh testing and the period of ultraviolet testing may be considered to be part of this soak, provided that the soak begins immediately after the slosh testing. To determine the final permeation rate, the fuel tank shall be drained and refilled with fresh test fuel as set out in Appendix 2 to Annex II. The permeation test run laid down in point 4 shall be repeated immediately after this soak period. The same test fuel requirement shall be used for this permeation test run as for the permeation test run conducted prior to the durability testing. The final test results shall be calculated in accordance with point 5.
6.3.   The manufacturer may request that any of the durability tests be excluded if it can be clearly demonstrated to the approval authorities that this does not affect the emissions from the fuel tank.
6.4.   The length of ‘soak’ during durability testing may be included in the fuel soak period provided that fuel remains in the tank. Soak periods may be shortened to ten weeks if performed at 316,2 ± 5 K (43 ± 5 °C).
7.   Fuel line assembly test requirements

7.1.   Fuel line assembly permeation physical testing procedure

Typically, the heat sources will be electric heating strips, but other sources may be used at the request of the manufacturer. Temperature controllers may be manual, such as variable transformers, or automated. Since vapour and fuel temperature are to be controlled separately, an automatic controller is recommended for the fuel. The heating system shall not cause hot-spots on the wetted surface of the tank which would cause local overheating of the fuel. Heating strips for the fuel should be located as low as practicable on the fuel tank and shall cover at least 10 % of the wetted surface. The centre line of the heating strips shall be below 30 % of the fuel depth as measured from the bottom of the fuel tank, and approximately parallel to the fuel level in the tank. The centre line of the vapour heating strips, if used, shall be located at the approximate height of the centre of the vapour volume. The temperature controllers shall be capable of controlling the fuel and vapour temperatures to the heating function described in 5.3.1.6.
4.4.2.   With temperature sensors positioned as in point 4.5.2., the fuel heating device shall make it possible to evenly heat the fuel and fuel vapour in the tank in accordance with the heating function described in 5.3.1.6. The heating system shall be capable of controlling the fuel and vapour temperatures to ± 1,7 K of the required temperature during the tank heating process.
4.4.3.   Notwithstanding the requirements of point 4.4.2., if a manufacturer is unable to meet the heating requirement specified, due to use of thick-walled plastic fuel tanks for example, then the closest possible alternative heat slope shall be used. Prior to the commencement of any test, the manufacturer shall submit engineering data to the technical service to support the use of an alternative heat slope.
4.5.   Temperature recording

4.5.2.   The temperatures of the fuel and fuel vapour shall be recorded by means of sensors positioned in the fuel tank as described in point 5.1.1. When sensors cannot be positioned as specified in point 5.1.1, e.g. where a fuel tank with two ostensibly separate chambers is used, sensors shall be located at the approximate mid-volume of each fuel- or vapour-containing chamber. In this case, the average of these temperature readings shall constitute the fuel and vapour temperatures.
4.5.3.   Throughout the evaporative emission measurements, temperatures shall be recorded or entered into a data processing system at a frequency of at least once per minute.
4.5.4.   The accuracy of the temperature recording system shall be within ± 1,7 K and capable of resolving temperatures to 0,5 K.

It shall be possible to attain an even temperature and hydrocarbon concentration in the chamber during measurements. The vehicle in the enclosure shall not be subjected to a direct stream of air from the fans or blowers.
4.7.   Gases
4.7.1.   The following pure gases shall be available for calibration and operation:






(a)


purified synthetic air (purity: < 1 ppm C1 equivalent < 1 ppm CO, < 400 ppm CO2, 0,1 ppm NO); oxygen content between 18 and 21 % by volume;










(b)


hydrocarbon analyser fuel gas (40 ± 2 % hydrogen, and balance helium with less than 1 ppm C1 equivalent hydrocarbon, less than 400 ppm CO2);










(c)


propane (C3H8), 99,5 % minimum purity.




4.7.2.   Calibration and span gases shall be available containing mixtures of propane (C3H8) and purified synthetic air. The true concentrations of a calibration gas shall be within ± 2 % of the stated figures. The accuracy of the diluted gases obtained when using a gas divider shall be to within ± 2 % of the true value.

5.3.1.   Tank breathing (diurnal) evaporative emission test








5.3.1.1.


The measuring chamber shall be vented/purged for several minutes immediately before the test until a stable background is obtainable. The chamber mixing fan(s) shall be switched on at this time also.












5.3.1.2.


The hydrocarbon analyser shall be set to zero and spanned immediately before the test.












5.3.1.3.


The fuel tanks shall be emptied as described in point 5.1.1 and refilled with test fuel at a temperature of between 283,2 K and 287,2 K (10 °C and 14 °C) to 50 ± 2 % of its normal volumetric capacity.












5.3.1.4.


The test vehicle shall be brought into the test enclosure with the engine switched off and parked in an upright position. The fuel tank sensors and heating device shall be connected, if necessary. Immediately begin recording the fuel temperature and the air temperature in the enclosure. If a venting/purging fan is still operating, it shall be switched off at this time.












5.3.1.5.


The fuel and vapour may be artificially heated to the starting temperatures of 288,7 K (15,5 °C) and 294,2 K (21,0 °C) ± 1 K respectively.

As soon as the fuel temperature reaches 287,0 K (14,0 °C):






(1)


Install the fuel filler cap(s);










(2)


Turn off the purge blowers, if not already off at that time;










(3)


Close and seal enclosure doors.




As soon as the fuel reaches a temperature of 288,7 K (15,5 °C) ± 1 K the test procedure shall continue as follows:






(a)


the hydrocarbon concentration, barometric pressure and the temperature shall be measured to give the initial readings CHC, i, Pi and Ti for the tank heat build test;










(b)


a linear heat build of 13,8 K or 20 ± 0,5 K over a period of 60 ± 2 minutes shall begin. The temperature of the fuel and fuel vapour during the heating shall conform to the result of equation Ap3-1 within ± 1,7 K, or the closest possible function as described in 4.4.3:

where:







Tf



=


required temperature of fuel (K);




Tv



=


required temperature of vapour (K);




t


=


time from start of the tank heat build in minutes.
























5.3.1.7.


The hydrocarbon analyser is set to zero and spanned immediately before the end of the test.












5.3.1.8.


If the heating requirements in point 5.3.1.6. have been met over the 60 ± 2 minute period of the test, the final hydrocarbon concentration in the enclosure is measured (CHC,f). The time or elapsed time of this measurement is recorded, together with the final temperature and barometric pressure Tf and pf.












5.3.1.9.


The heat source is turned off and the enclosure door unsealed and opened. The heating device and temperature sensor are disconnected from the enclosure apparatus. The vehicle is now removed from the enclosure with the engine switched off.












5.3.1.10.


To prevent abnormal loading of the canister, fuel tank caps may be removed from the vehicle during the period between the end of the diurnal test phase and the start of the driving cycle. The driving cycle shall begin within 60 minutes of the completion of the breathing loss test.




5.3.2.   Driving cycle








5.3.2.1.


‘Tank breathing losses’ means hydrocarbon emissions caused by temperature changes in the fuel storage and supply. Following the tank breathing losses test, the vehicle is pushed or otherwise manoeuvred onto the chassis dynamometer with the engine switched off. It is then driven through the driving cycle specified for the class of vehicle on test. At the request of the manufacturer, exhaust emissions may be sampled during this operation, but the results shall not be used for the purpose of exhaust emission type-approval.




5.3.3.   Hot soak evaporative emissions test
The determination for evaporative emissions is concluded with the measurement of hydrocarbon emissions over a 60-minute hot soak period. The hot soak test shall begin within seven minutes of the completion of the driving cycle specified in point 5.3.2.1.






5.3.3.1.


Before the completion of the test run, the measuring chamber shall be purged for several minutes until a stable hydrocarbon background is obtained. The enclosure mixing fan(s) shall also be turned on at this time.










5.3.3.2.


The hydrocarbon analyser shall be set to zero and spanned immediately prior to the test.










5.3.3.3.


The vehicle shall be pushed or otherwise moved into the measuring chamber with the engine switched off.










5.3.3.4.


The enclosure doors are closed and sealed gas-tight within seven minutes of the end of the driving cycle.










5.3.3.5.


A 60 ± 0,5 minute hot soak period begins when the chamber is sealed. The hydrocarbon concentration, temperature and barometric pressure are measured to give the initial readings CHC, i. Pi and Ti for the hot soak test. These figures are used in the evaporative emission calculation shown in chapter 6.










5.3.3.6.


The hydrocarbon analyser shall be zeroed and spanned immediately before the end of the 60 ± 0,5 minute test period.










5.3.3.7.


At the end of the 60 ± 0,5 minute test period, measure the hydrocarbon concentration in the chamber. The temperature and the barometric pressure are also measured. These are the final readings CHC, f. pf and Tf for the hot soak test used for the calculation in chapter 6. This completes the evaporative emission test procedure.




5.4.   Alternative test procedures
5.4.1.   At the request of the manufacturer, with the agreement of the technical service and to the satisfaction of the approval authority, alternative methods may be used to demonstrate compliance with the requirements of this Appendix. In such cases, the manufacturer shall satisfy the technical service that the results from the alternative test can be correlated with those resulting from the procedure described in this Annex. This correlation shall be documented and added to the information folder provided for in Article 27 of Regulation (EU) No 168/2013.
6.   Calculation of results

6.1.   The evaporative emission tests described in chapter 5 allow the hydrocarbon emissions from the tank breathing and hot soak phases to be calculated. Evaporative losses from each of these phases is calculated using the initial and final hydrocarbon concentrations, temperatures and pressures in the enclosure, together with the net enclosure volume.
The following formula shall be used:

Equation Ap3-3:






where:







MHC



=


mass of hydrocarbon emitted over the test phase (grams);




CHC



=


hydrocarbon concentration measured in the enclosure (ppm (volume) Ci equivalent);




V


=


net enclosure volume in cubic metres corrected for the volume of the vehicle. If the volume of the vehicle is not determined, a volume of 0,14 m3 shall be subtracted;




T


=


ambient chamber temperature in K;




p


=


barometric pressure in kPa;




H/C


=


hydrogen to carbon ratio;









where:






 


i is the initial reading;










 


f is the final reading;










 


H/C is taken to be 2,33 for tank breathing losses;










 


H/C is taken to be 2,20 for hot soak losses. ‘Hot soak losses’ means hydrocarbon emissions arising from the fuel system of a stationary vehicle after a period of driving (assuming a ratio of C1 H2,20 );




6.2.   Overall results of test
The overall evaporative hydrocarbon mass emission for the vehicle is taken to be:

Equation Ap3-4:






where:







Mtotal



=


overall evaporative mass emissions of the vehicle (grams);




MTH



=


evaporative hydrocarbon mass emission for the tank heat build (grams);




MHS



=


evaporative hydrocarbon mass emission for the hot soak (grams).




7.   Limit values

When tested according to this Annex, overall evaporative hydrocarbon mass emission for the vehicle (Mtotal) shall be as specified in Part C of Annex VI to Regulation (EU) No 168/2013.
8.   Further provisions

At the request of the manufacturer, evaporative emission approval shall be granted without testing if a California Executive Order for the vehicle type with regard to environmental performance for which application is made can be provided to the approval authority.

3.2.


Alternatively, the aged evaporative emission control parts tested according to point 3.1. may be replaced with ‘golden’ evaporation emission control valves, cables and linkages complying with the requirements of point 3.5. of Annex VI, to be installed on the type IV test vehicle at the choice of the manufacturer prior to start of the SHED test referred to in Appendix 3.




4.   Reporting

The manufacturer shall report the results of the tests referred to in points 2 and 3 in a test report drafted according to the template referred to in Article 32(1) of Regulation (EU) No 168/2013.




Appendix 4

Calibration of equipment for evaporative emission testing

1.   Calibration frequency and methods

1.1.   All equipment shall be calibrated before its initial use and then as often as necessary, and in any case in the month before type-approval testing. The calibration methods to be used are described in this Appendix.
2.   Calibration of the enclosure

2.1.   Initial determination of enclosure internal volume








2.1.1.


Before its initial use, the internal volume of the chamber shall be determined as follows. The internal dimensions of the chamber are carefully measured, allowing for any irregularities such as bracing struts. The internal volume of the chamber is determined from these measurements.












2.1.2.


The net internal volume is determined by subtracting 0,14 m3 from the internal volume of the chamber. Alternatively, the actual volume of the test vehicle may be subtracted.












2.1.3.


The chamber shall be checked as in point 2.3. If the propane mass does not tally to within ± 2 % with the injected mass, corrective action is required.




2.2.   Determination of chamber background emissions
This operation determines that the chamber contains no materials that emit significant amounts of hydrocarbons. The check shall be carried out when the enclosure is brought into service, after any operations in it which may affect background emissions and at least once per year.






2.2.1.


Calibrate the analyser (if required). The hydrocarbon analyser shall be set to zero and spanned immediately before the test.










2.2.2.


Purge the enclosure until a stable hydrocarbon reading is obtained. The mixing fan is turned on, if not already on.










2.2.3.


Seal the chamber and measure the background hydrocarbon concentration, temperature and barometric pressure. These are the initial readings CHCi. pi and Ti used in the enclosure background calculation.










2.2.4.


The enclosure is allowed to stand undisturbed with the mixing fan on for four hours.










2.2.5.


The hydrocarbon analyser shall be set to zero and spanned immediately before the end of the test.










2.2.6.


At the end of this time, use the same analyser to measure the hydrocarbon concentration in the chamber. The temperature and the barometric pressure are also measured. These are the final readings CHCf. Pf and Tf.










2.2.7.


Calculate the change in mass of hydrocarbons in the enclosure over the time of the test in accordance with point 2.4. The background emission of the enclosure shall not exceed 0,4 g.




2.3.   Calibration and hydrocarbon retention test of the chamber
The calibration and hydrocarbon retention test in the chamber provides a check on the calculated volume in point 2.1. and also measures any leak rate.






2.3.1.


Purge the enclosure until a stable hydrocarbon concentration is reached. Turn on the mixing fan, if it is not already on. The hydrocarbon analyser shall be calibrated (if necessary) then set to zero and spanned immediately before the test.










2.3.2.


Seal the enclosure and measure the background concentration, temperature and barometric pressure. These are the initial readings CHCi., pi and Ti used in the enclosure calibration.










2.3.3.


Inject approximately 4 grams of propane into the enclosure. The mass of propane shall be measured to an accuracy of ± 2 % of the measured value.










2.3.4.


Allow the contents of the chamber to mix for five minutes. The hydrocarbon analyser shall be set to zero and spanned immediately before the following test. Measure the hydrocarbon concentration, temperature and barometric pressure. These are the final readings CHCf, pf and Tf for the calibration of the enclosure.










2.3.5.


Using the readings taken in accordance with points 2.3.2 and 2.3.4 and the formula in point 2.4, calculate the mass of propane in the enclosure. This shall be within ± 2 % of the mass of propane measured in accordance with point 2.3.3.










2.3.6.


Allow the contents of the chamber to mix for a minimum of four hours. Then measure and record the final hydrocarbon concentration, temperature and barometric pressure. The hydrocarbon analyser shall be set to zero and spanned immediately before the end of the test.










2.3.7.


Using the formula in 2.4, calculate the hydrocarbon mass from the readings taken in points 2.3.6 and 2.3.2. The mass may not differ by more than 4 % from the hydrocarbon mass calculated in accordance with point 2.3.5.




2.4.   Calculations
The calculation of net hydrocarbon mass change within the enclosure shall be used to determine the chamber’s hydrocarbon background and leak rate. Initial and final readings of hydrocarbon concentration, temperature and barometric pressure are used in the following formula to calculate the mass change:

Equation Ap3-5:






where:







MHC



=


mass of hydrocarbon in grams;




CHC



=


hydrocarbon concentration in the enclosure (ppm carbon (NB:

ambient temperature in the enclosure, K;




p


=


barometric pressure in kPa;

17,6;




where:






 


i is the initial reading;










 


f is the final reading.




3.   Checking of FID hydrocarbon analyser

3.1.   Detector response optimisation
The FID analyser shall be adjusted as specified by the instrument manufacturer. Propane in air shall be used to optimise the response on the most common operating range.
3.2.   Calibration of the HC analyser
The analyser shall be calibrated using propane in air and purified synthetic air. A calibration curve shall be established as described in points 4.1 to 4.5.
3.3.   Oxygen interference check and recommended limits
The response factor (Rf) for a particular hydrocarbon species is the ratio of the FID C1 reading to the gas cylinder concentration, expressed as ppm C1.
The concentration of the test gas shall be such as to give a response of approximately 80 % of full scale deflection, for the operating range. The concentration shall be known to an accuracy of ± 2 % in reference to a gravimetric standard expressed in volume. In addition, the gas cylinder shall be preconditioned for 24 hours at between 293,2 K and 303,2 K (20 °C and 30 °C).
Response factors shall be determined when introducing an analyser into service and thereafter at major service intervals. The reference gas to be used is propane balanced with purified air which shall be taken to give a response factor of 1,00.
The test gas to be used for oxygen interference and the recommended response factor range are given the following response factor range for Propane and Nitrogen: 0,95 ≤ Rf ≤ 1,05.
4.   Calibration of the hydrocarbon analyser

Each of the normally used operating ranges are calibrated by the following procedure:






4.1.


Establish the calibration curve by at least five calibration points spaced as evenly as possible over the operating range. The nominal concentration of the calibration gas with the highest concentrations shall be at least 80 % of the full scale.










4.2.


Calculate the calibration curve by the method of least squares. If the resulting polynomial degree is greater than 3, then the number of calibration points shall be at least the number of the polynomial degree plus 2.










4.3.


The calibration curve shall not differ by more than 2 % from the nominal value of each calibration gas.










4.4.


Using the coefficients of the polynomial derived from point 4.2, a table of indicated reading against true concentration shall be drawn up in steps of no greater than 1 % of full scale. This is to be carried out for each analyser range calibrated. The table shall also contain all of the following:






(a)


date of calibration;










(b)


span and zero potentiometer readings (where applicable), nominal scale;










(c)


reference data of each calibration gas used;










(d)


the actual and indicated value of each calibration gas used together with the percentage differences.














4.5.

The same inertia and flywheel settings and calibration procedures shall be used for the chassis dynamometer used to accumulate mileage with the test vehicles set out in Annex II to Regulation (EU) No 168/2013;










2.1.2.


the test vehicles may be moved to a different chassis dynamometer in order to conduct type I emission verification tests. This dynamometer shall enable the SRC-LeCV to be carried out;










2.1.3.

Any stops for type I emission tests, maintenance, soak periods, refuelling, etc. shall be performed at the end of one complete SRC-LeCV sub-cycle, i.e. the culmination of step 47 in Table Ap1-4. If the vehicle travels to the testing area under its own power, only moderate acceleration and deceleration shall be used and the vehicle shall not be operated at full throttle.
2.5.   The four cycles shall be selected on the basis of the maximum design vehicle speed of the L-category vehicle and the engine capacity or, in the case of pure electric or hybrid propulsions, the maximum design speed of the vehicle and the net power.
2.6.   For the purpose of accumulating mileage in the SRC-LeCV, the L-vehicle categories shall be grouped as follows:

2.7.   SRC-LeCV general driving instructions
2.7.1.   Idle instructions








2.7.1.1.


If not already stopped, the vehicle shall decelerate to a full stop and the gear shifted to neutral. The throttle shall be fully released and ignition shall remain on. If a vehicle is equipped with a stop-start system or, in the case of a hybrid electric vehicle, the combustion engine switches off when the vehicle is stationary; it shall be ensured that the combustion engine continues to idle.












2.7.1.2.


The vehicle shall not be prepared for the following action in the test cycle until the full required idle duration has passed.




2.7.2.   Acceleration instructions:






2.7.2.1.


accelerate to the target vehicle speed using the following sub-action methodologies:
2.7.2.1.1.   moderate: normal medium part-load acceleration, up to approximately half throttle.
2.7.2.1.2.   hard: high part-load acceleration up to full throttle.










2.7.2.2.


if moderate acceleration is no longer able to provide a noticeable increase in actual vehicle speed to reach a target vehicle speed, then hard acceleration shall be used and ultimately full throttle.




2.7.3.   Deceleration instructions:






2.7.3.1.


decelerate from either the previous action or from the maximum vehicle speed attained in the previous action, whichever is lower.










2.7.3.2.


if the next action sets the target vehicle speed at 0 km/h, the vehicle shall be stopped before proceeding.










2.7.3.3.


moderate deceleration: normal let-off of the throttle; brakes, gears and clutch may be used as required.










2.7.3.4.


coast-through deceleration: full let-off of the throttle, clutch disengaged and in gear, no foot/hand control actuated, no brakes applied. If the target speed is 0 km/h (idle) and if the actual vehicle speed is ≤ 5 km/h, the clutch may be disengaged, the gear shifted to neutral and the brakes used in order to prevent engine stall and to entirely stop the vehicle. An upshift is not allowed during a coast-through deceleration. The rider may downshift to increase the braking effect of the engine. During gear changes, extra care shall be afforded to ensure that the gear change is performed promptly, with minimum (i.e. < 2 seconds) coasting in neutral gear, clutch and partial clutch use. The vehicle manufacturer may request to extend this time with the agreement of the approval authority if absolutely necessary.










2.7.3.5.


coast-down deceleration: deceleration shall be initiated by de-clutching (i.e. separating the drive from the wheels) without the use of brakes until the target vehicle speed is reached.




2.7.4.   Cruise instruction:






2.7.4.1.


if the following action is ‘cruise’, the vehicle may be accelerated to attain the target vehicle speed.










2.7.4.2.


the throttle shall continue to be operated as required to attain and remain at the target cruising vehicle speed.




2.7.5.   A driving instruction shall be performed in its entirety. Additional idling time, acceleration to above, and deceleration to below, the target vehicle speed is permitted in order to ensure that actions are performed fully.
2.7.6.   Gear changes should be carried out according to the guidance laid down in point 4.5.5. of Appendix 9 of Annex II. Alternatively, guidance provided by the manufacturer to the consumer may be used if approved by the approval authority.
2.7.7.   Where the test vehicle cannot reach the target vehicle speeds set out in the applicable SRC-LeCV, it shall be operated at wide open throttle and using other available options to attain maximum design speed.
2.8.   SRC-LeCV test steps
The SRC-LeCV test shall consist of the following steps:






2.8.1.


the maximum design speed of the vehicle and either the engine capacity or net power, as applicable, shall be obtained;










2.8.2.


the required SRC-LeCV shall be selected from Table Ap1-1 and the required target vehicle speeds and detailed driving instructions from Table Ap1-3.










2.8.3.


the column ‘decelerate by’ shall indicate the delta vehicle speed to be subtracted either from the previously attained target vehicle speed or from the maximum design vehicle speed, whichever is lower.
Example lap 1:






 


vehicle No 1: L1e-B low-speed moped with maximum design vehicle speed of 25 km/h, subject to SRC-LeCV No 1










 


vehicle No 2: L1e-B high-speed moped with maximum design vehicle speed of 45 km/h, subject to SRC-LeCV No 1

2.8.4.


A table of target vehicle speeds shall be prepared indicating the nominal target vehicle speeds set out in Tables Ap1-3 and Ap-4 and the attainable target vehicle speeds of the vehicle in a format preferred by the manufacturer to the satisfaction of the approval authority.










2.8.5.


In accordance with point 2.2.5., quarter divisions of the lap length shall be marked or identified on the test track or road, or a system shall be used to indicate the distance being passed on the chassis dynamometer.










2.8.6.


After each sub-lap is passed, the required list of actions of Tables Ap1-3 and Ap-4 shall be performed in order and in accordance with point 2.7 regarding the general driving instructions to or at the next target vehicle speed.










2.8.7.


The maximum attained vehicle speed may deviate from the maximum design vehicle speed depending on the type of acceleration required and track conditions. Therefore, during the test the actual attained vehicle speeds shall be monitored to see if the target vehicle speeds are being met as required. Special attention shall be paid to peak vehicle speeds and cruise vehicle speeds close to the maximum design vehicle speed and the subsequent vehicle speed differences in the decelerations.










2.8.8.


Where a significant deviation is consistently found when performing multiple sub-cycles, the target vehicle speeds shall be adjusted in the table in point 2.8.4. The adjustment needs to be made only when starting a sub-cycle and not in real time.

Appendix 2

The USA EPA Approved Mileage Accumulation durability cycle (AMA)

1.   Introduction









1.1.


The Approved Mileage Accumulation durability cycle (AMA) by the environmental protection agency (EPA) of the United States of America (USA) is a mileage accumulation cycle used to age test vehicles and their pollution-control devices in a way that is repeatable but significantly less representative for the EU fleet and traffic situation than the SRC-LeCV. The AMA test cycle is to be phased out but it may be used in a transitional period up to and including the date of last registration set out in point 1.5.2. of Annex IV to Regulation (EU) No 168/2013, pending the confirmation in the environmental effect study referred to in Article 23(4) of Regulation (EU) No 168/2013. The L-category test vehicles may run the test cycle on the road, on a test track or on a kilometre accumulation chassis dynamometer.












1.2.


The AMA test cycle shall be completed by repeating the AMA sub-cycle in point 2 until the applicable durability mileage in Part A of Annex VII to Regulation (EU) No 168/2013 has been accumulated.












1.3.


The AMA test cycle shall be composed of 11 sub-sub-cycles covering six kilometres each.




2.   AMA test cycle requirements









2.1.


For the purpose of accumulating mileage in the AMA test cycle, the L-category vehicles shall be grouped as follows:

Table Ap2-1


Grouping of L-category vehicles for the purpose of the AMA mileage accumulation test








L-category vehicle class

>130
















2.2.


If the AMA test cycle is performed on a kilometre accumulation chassis dynamometer, the distance travelled shall be calculated from the number of rotations of the roller and the roller circumference.












2.3.


One AMA test sub-cycle shall be performed as follows:






2.5.1.

2.5.3.


Manufacturers may select one of two cycle vehicle speed options for class III L-category vehicles, completing the entire procedure on their selected option.










2.5.4.


During the first nine AMA sub-sub-cycles, the test vehicle is stopped four times with the engine idling each time for 15 seconds.










2.5.5.


The AMA sub-cycle shall consist of five decelerations in each sub-sub-cycle, dropping from cycle speed to 30 km/h. The test vehicle shall then gradually be accelerated again until the cycle speed shown in Table Ap2-2 is attained.










2.5.6.


The 10th sub-sub-cycle shall be carried out at a steady speed according to the L-category vehicle class as referred in Table Ap2-1.










2.5.7.


The 11th sub-sub-cycle shall begin with a maximum acceleration from stop point up to lap speed. At halfway, the brakes are applied normally until the test vehicle comes to a stop. This shall be followed by an idle period of 15 seconds and a second maximum acceleration. This completes one AMA sub-cycle.










2.5.8.


The schedule shall then be restarted from the beginning of the AMA sub-cycle.










2.5.9.


At the manufacturer’s request, and with the agreement of the approval authority, an L-category vehicle type may be placed in a higher class provided it is capable of complying with all aspects of the procedure for the higher class.










2.5.10.


At the manufacturer’s request, and with the agreement of the approval authority, should the L-category vehicle be unable to attain the specified cycle speeds for that class, the L-category vehicle type shall be placed in a lower class. If the vehicle is unable to achieve the cycle speeds required for this lower class, it shall attain the highest possible speed during the test and full throttle shall be applied if necessary to attain that vehicle speed.

2.3.1.2.   The viscosity of the oils for the mechanical moving parts shall conform to the vehicle manufacturer’s specification.
2.3.1.3.   The lighting, signalling and auxiliary devices shall be off, except those required for the testing and usual day-time operation of the vehicle.
2.3.1.4.   All energy storage systems for other than traction purposes (electric, hydraulic, pneumatic, etc.) shall be charged to their maximum level as specified by the manufacturer.
2.3.1.5.   If the batteries are operated above the ambient temperature, the operator shall follow the procedure recommended by the vehicle manufacturer in order to keep the battery temperature in the normal operating range.
The manufacturer shall be in a position to attest that the thermal management system of the battery is neither disabled nor reduced.
2.3.1.6.   The vehicle shall have travelled at least 300 km in the seven days before the test with the batteries installed for the test.
2.3.2.   Classification of the pure electric test vehicle in the type I test cycle.
In order to measure its electric consumption in the type I test cycle, the test vehicle shall be classified according to the achievable maximum design vehicle speed thresholds only, set-out in point 4.3. of Annex II.
2.4.   Operation mode
All the tests are conducted at a temperature of between 293,2 K and 303,2 K (20 °C and 30 °C).
The test method includes the four following steps:






(a)


initial charge of the battery;










(b)


two runs of the applicable type I test cycle;










(c)


charging the battery;










(d)


calculation of the electric energy consumption.




If the vehicle moves between the steps, it shall be pushed to the next test area (without regenerative recharging).
2.4.1.   Initial charge of the battery
Charging the battery consists of the following procedures:
2.4.1.1.   Discharge of the battery
The battery is discharged while the vehicle is driven (on the test track, on a chassis dynamometer, etc.) at a steady speed of 70 percent ± 5 percent of the maximum design vehicle speed, as determined according to the test procedure in Appendix 1 to Annex X.
Discharging shall stop:






(a)


when the vehicle is unable to run at 65 percent of the maximum thirty minutes speed, or










(b)


when the standard on-board instrumentation indicates that the vehicle should be stopped, or










(c)


after 100 km.




By means of derogation if the manufacturer can prove to the technical service to the satisfaction of the approval authority that the vehicle is physically not capable of achieving the thirty minutes speed the maximum fifteen minute speed may be used instead.
2.4.1.2.   Application of a normal overnight charge
The battery shall be charged according to the following procedure:
2.4.1.2.1.   Normal overnight charge procedure
The charge shall be carried out:






(a)


with the on-board charger if fitted;










(b)


with an external charger recommended by the manufacturer, using the charging pattern prescribed for normal charging;










(c)


in an ambient temperature of between 293,2 K and 303,2 K (20 °C and 30 °C).




This procedure excludes all types of special charges that could be automatically or manually initiated, e.g. equalisation or servicing charges.
The vehicle manufacturer shall declare that no special charge procedure has occurred during the test.
2.4.1.2.2.   End-of-charge criteria
The end-of-charge criteria shall correspond to a charging time of 12 hours except where the standard instrumentation indicates clearly that the battery is not yet fully charged, in which case:

Equation Ap2-1:






2.4.1.2.3.   Fully charged battery
Propulsion batteries shall be deemed as fully charged when they have been charged according to the overnight charge procedure until the end-of-charge criteria are fulfilled.
2.4.2.   Application of the type I test cycle and measurement of the distance
The end of charging time t0 (plug off) shall be reported.
The chassis dynamometer shall be set according to the method in point 4.5.6. of Annex II.
Starting within four hours of t0, the applicable type I test shall be run twice on a chassis dynamometer, following which the distance covered in km (Dtest) is recorded. If the manufacturer can demonstrate to the approval authority that twice the type I test distance can physically not be attained by the vehicle, the test cycle shall be conducted once and subsequently followed by a partial second test run. The second test run may stop if the minimum state of charge of the propulsion battery is reached as referred to in Appendix 3.1.
2.4.3.   Charge of the battery
The test vehicle shall be connected to the mains within 30 minutes of the second run of the applicable type I test cycle.
The vehicle shall be charged according to the normal overnight charge procedure in point 2.4.1.2.
The energy measurement equipment, placed between the mains socket and the vehicle charger, measures the energy charge E delivered from the mains and its duration.
Charging shall stop 24 hours after the end of the previous charging time (t0).

Note:

In the event of a mains power cut, the 24 hour period may be extended in line with the duration of the cut. The validity of the charge shall be discussed between the technical services of the approval laboratory and the vehicle manufacturer to the satisfaction of the approval authority.
2.4.4.   Electric energy consumption calculation
Energy E in Wh and charging time measurements are to be recorded in the test report.
The electric energy consumption c shall be determined using the formula:

Equation Ap2-2:




 (expressed in Wh/km and rounded to the nearest whole number)
where Dtest is the distance covered during the test (in km).

(a)


to determine when the battery’s minimum state of charge has been reached during the test procedure in points 3.3. and 4.3. of Appendix 3, and

to adjust the fuel consumption and CO2-emissions measurements in line with the change in battery energy content during the test, using the method in points 5.3.1.1. and 6.3.1.1. of Appendix 3.
















1.2.


The method described in this Appendix shall be used by the manufacturer for taking the measurements to determine the correction factors Kfuel and KCO2

Original equipment manufacturer diagnostic testers are not to be used for the purpose of this test.






2.1.1.


The current transducer shall be fitted on one of the wires directly connected to the battery. To make it easier to measure the battery current with external equipment, the manufacturer shall integrate appropriate, safe and accessible connection points in the vehicle. If that is not feasible, the manufacturer is obliged to support the technical service by providing the means to connect a current transducer to the wires connected to the battery as described in point 2.1.










2.1.2.


The output of the current transducer shall be sampled with a minimum sample frequency of 5 Hz. The measured current shall be integrated over time, yielding the measured value of Q, expressed in Ampere hours (Ah).










2.1.3.


The temperature at the location of the sensor shall be measured and sampled with the same sample frequency as the current, so that this value can be used for possible compensation of the drift of current transducers and, if applicable, the voltage transducer used to convert the output of the current transducer.
















2.2.


The technical service shall be provided with a list of the instrumentation (manufacturer, model number, serial number) used by the manufacturer for determining the correction factors Kfuel and KCO2
 set out in Appendix 3 and the last calibration dates of the instruments, where applicable.




3.   Measurement procedure

Measurement of the battery current shall start at the beginning of the test and end immediately after the vehicle has driven the complete driving cycle.












3.2.


Separate values of Q shall be logged over the parts (cold/warm or phase 1 and, if applicable, phases 2 and 3) of the type I test cycle set out in Annex II.

Appendix 1

Sound level test requirements for powered cycles and two-wheel mopeds (category L1e)







1.


Definitions




For the purposes of this Appendix:






1.1.


‘type of powered cycle or two-wheel moped as regards its sound level and exhaust system’ means L1e vehicles which do not differ in such essential respects as the following:






1.1.1.


type of engine (two- or four-stroke, reciprocating piston engine or rotary-piston engine, number and capacity of cylinders, number and type of carburettors or injection systems, arrangement of valves, maximum net power and corresponding speed). The cubic capacity of rotary-piston engines shall deemed to be double the volume of the chamber;










1.1.2.


Drive train, in particular the number and ratios of the gears of the transmission and the final ratio;










1.1.3.


number, type and arrangement of exhaust systems;














1.2.


‘exhaust system’ or ‘silencer’ means a complete set of components necessary to limit the noise caused by a moped engine and its exhaust;






1.2.1.


‘original exhaust system or silencer’ means a system of the type fitted to the vehicle at the time of the environmental performance type-approval or extension of type-approval. It may be that first fitted or a replacement;










1.2.2.


‘non-original exhaust system or silencer’ means a system of a type other than that fitted to the vehicle at the time of the environmental performance type-approval or extension of type-approval. It may be used only as a replacement exhaust system or silencer;














1.3.


‘exhaust systems of differing types’ means systems which are fundamentally different in one of the following ways:






1.3.1.


systems comprising components bearing different factory markings or trademarks;










1.3.2.


systems comprising any component made of materials of different characteristics or comprising components which are of a different shape or size;










1.3.3.


systems in which the operating principles of at least one component are different;










1.3.4.


systems comprising components in different combinations;














1.4.


‘component of an exhaust system’ means one of the individual components which together form the exhaust system (such as exhaust pipe work, the silencer proper) and the air intake system (air filter), if any.
If the engine has to be equipped with an air intake system (air filter or intake noise absorber) in order to comply with the maximum permissible sound levels, the filter or the absorber shall be treated as components having the same importance as the exhaust system.




2.   Component type-approval in respect of the sound level and original exhaust system, as a separate technical unit, of a type of two-wheel moped

2.1.   Noise made by the two-wheel moped in motion (measuring conditions and method for testing of the vehicle during component type-approval)
2.1.1.   Noise limits: see Part D of Annex VI to Regulation (EU) No 168/2013.
2.1.2.   Measuring instruments
2.1.2.1.   Acoustic measurements
The apparatus used for measuring the sound-level shall be a precision sound-level meter of the type described in International Electro-technical Commission (IEC) publication 179 Precision sound-level meters, second edition. Measurements shall be taken using the ‘fast’ response and the ‘A’ weighting also described in that publication.
At the beginning and end of each series of measurements, the sound-level meter shall be calibrated in accordance with the manufacturer’s instructions, using an appropriate noise source (e.g. piston phone).
2.1.2.2.   Speed measurements
Engine speed and moped speed on the test track shall be determined to within ± 3 %.
2.1.3.   Conditions of measurement
2.1.3.1.   Condition of the moped
The combined weight of the rider and the test equipment used on the moped shall be between 70 kg and 90 kg. If necessary, weights shall be added to the moped to bring the combined weight up to at least 70 kg.
During the measurements, the moped shall be in running order (including coolant, oils, fuel, tools, spare wheel and rider).
Before the measurements are taken, the moped shall be brought to the normal operating temperature.
If the moped is fitted with fans with an automatic actuating mechanism, this system shall not be interfered with during the sound measurements. For mopeds with more than one driven wheel, only the drive provided for normal road operation may be used. Where a moped is fitted with a sidecar, this shall be removed for the purposes of the test.
2.1.3.2.   Test site
The test site shall consist of a central acceleration section surrounded by a substantially flat test area. The acceleration section shall be flat; its surface shall be dry and such that surface noise remains low.
On the test site, the variations in the free sound field between the sound source at the centre of the acceleration section and the microphone shall not exceed 1 dB. This condition will be deemed to be met if there are no large objects which reflect sound, such as fences, rocks, bridges or buildings, within 50 m of the centre of the acceleration section. The surface covering of the test track shall conform to the requirements of Appendix 7.
The microphone shall not be obstructed in any way which could affect the sound field, and no person may stand between the microphone and the sound source. The observer taking the measurements shall so position himself as not to affect the readings of the measuring instrument.
2.1.3.3.   Miscellaneous
Measurements shall not be taken in poor atmospheric conditions. It shall be ensured that the results are not affected by gusts of wind.
For measurements, the A-weighted sound level of sound sources other than those of the vehicle to be tested and of wind effects shall be at least 10 dB(A) below the sound level produced by the vehicle. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the microphone’s sensitivity and directional characteristics.
If the difference between the ambient noise and the noise to be measured is between 10 and 16 dB(A), the test results shall be calculated by subtracting the appropriate correction from the readings on the sound-level meter, as in the following graph:

Figure Ap1-1


Difference between ambient noise and noise to be measured




2.1.4.   Method of measurement
2.1.4.1.   Nature and number of measurements
The maximum sound level expressed in A-weighted decibels (dB(A)) shall be measured as the moped travels between lines AA′ and BB′ (Figure Ap1-2). The measurement will be invalid if an abnormal discrepancy is recorded between the peak value and the general noise level. At least two measurements shall be taken on each side of the moped.
2.1.4.2.   Positioning of the microphone
The microphone shall be positioned 7,5 m ± 0,2 m from the reference line CC′ (Figure Ap1-2) of the track and 1,2 m ± 0,1 m above ground level.
2.1.4.3.   Conditions of operation
The moped shall approach line AA′ at an initial steady speed as specified in point 2.1.4.3.1 and 2.1.4.3.2. When the front of the moped reaches line AA′, the throttle shall be fully opened as quickly as practically possible and kept in that position until the rear of the moped reaches line BB′; the throttle shall then be returned as quickly as possible to the idle position.
For all measurements, the moped shall be ridden in a straight line over the acceleration section, keeping the median longitudinal plane of the moped as close as possible to line CC′.
2.1.4.3.1.   Approach speed
The moped shall approach line AA′ at a steady speed of 30 km/h or at its top speed if this is less.
2.1.4.3.2.   Selection of gear ratio
If the moped is fitted with a manual-shift gearbox, the highest gear which allows it to cross line AA′ at a speed at least half the full-power engine speed shall be selected.

2.2.1.   Sound-pressure level in the immediate vicinity of the moped
In order to facilitate subsequent noise tests on mopeds in use, the sound-pressure level in the immediate vicinity of the exhaust-system outlet (silencer) shall be measured in accordance with the following requirements, the result being entered in the test report drawn up for the purpose of issuing the document according to the template referred to in Article 32(1) of Regulation (EU) No 168/2013.
2.2.2.   Measuring instruments
A precision sound-level meter as defined in point 2.1.2.1 shall be used.
2.2.3.   Conditions of measurement
2.2.3.1.   Condition of the moped
Before the measurements are taken, the moped engine shall be brought to normal operating temperature. If the moped is fitted with fans with an automatic actuating mechanism, this system shall not be interfered with during the noise measurements.
During the measurements, the gearbox shall be in neutral gear. If it is impossible to disconnect the drive train, the driving wheel of the moped shall be allowed to rotate freely, e.g. by placing the vehicle on its centre stand.

In relation to this vertical plane, the microphone shall be positioned on the side on which there is the maximum possible distance between the microphone and the outline of the moped (handlebars excluded).
If the exhaust system has more than one outlet at centres less than 0,3 m apart, the microphone shall face the outlet which is nearest the moped (handlebars excluded) or the outlet which is highest above the surface of the track. If the centres of the outlets are more than 0,3 m apart, separate measurements shall be taken for each of them; the highest figure recorded being taken as the test value.
2.2.4.3.   Operating conditions
The engine speed shall be held steady at:






 


((S)/(2)) if S is more than 5 000 rpm; or










 


((3S)/(4)) if S is 5 000 rpm or less,




where ‘S’ is the engine speed at which maximum power is developed.
When a constant engine speed is reached, the throttle shall be returned swiftly to the idle position. The noise level shall be measured during an operating cycle consisting of a brief period of constant engine speed and throughout the deceleration period, the highest sound-level meter reading being taken as the test value.

Appendix 2

Sound level test requirements for motorcycles (categories L3e and L4e)

1.   Definitions

For the purposes of this Appendix:






1.1.


‘type of motorcycle as regards its sound level and exhaust system’ means motorcycles which do not differ in such essential respects as the following:






1.1.1.


type of engine (two- or four-stroke, reciprocating piston engine or rotary-piston engine, number and capacity of cylinders, number and type of carburettors or injection systems, arrangement of valves, net maximum power and corresponding speed). The cubic capacity of rotary-piston engines shall deemed to be double the volume of the chamber;










1.1.2.


Drive train, in particular the number and ratios of the gears of the transmission and final ratio;










1.1.3.


number, type and arrangement of exhaust systems;














1.2.


‘exhaust system’ or ‘silencer’ means a complete set of components necessary to limit the noise caused by a motorcycle engine and its exhaust;






1.2.1.


‘original exhaust system or silencer’ means a system of the type fitted to the vehicle at the time of type-approval or extension of type-approval. It may be that first fitted or a replacement;










1.2.2.


‘non-original exhaust system or silencer’ means a system of a type other than that fitted to the vehicle at the time of type-approval or extension of type-approval. It may be used only as a replacement exhaust system or silencer;














1.3.


‘exhaust systems of differing types’ means systems which are fundamentally different in one of the following ways:






1.3.1.


systems comprising components bearing different factory markings or trademarks;










1.3.2.


systems comprising any component made of materials of different characteristics or comprising components which are of a different shape or size;










1.3.3.


systems in which the operating principles of at least one component are different;

2.   Component type-approval in respect of the sound level and original exhaust system, as a separate technical unit, of a type of motorcycle

2.1.   Noise of the motorcycle in motion (measuring conditions and method for testing of the vehicle during component type-approval)
2.1.1.   Limits: see Part D of Annex VI to Regulation (EU) No 168/2013.
2.1.2.   Measuring instruments
2.1.2.1.   Acoustic measurements
The apparatus used for measuring the sound level shall be a precision sound-level meter of the type described in International Electro-technical Commission (IEC) publication 179 Precision sound-level meters, second edition. Measurements shall be taken using the ‘fast’ response and the ‘A’ weighting also described in that publication.
At the beginning and end of each series of measurements, the sound-level meter shall be calibrated in accordance with the manufacturer’s instructions, using an appropriate noise source (e.g. piston phone).
2.1.2.2.   Speed measurements
Engine speed and motorcycle speed on the test track shall be determined to within ± 3 %.
2.1.3.   Conditions of measurement
2.1.3.1.   Condition of the motorcycle
During the measurements, the motorcycle shall be in running order.
Before the measurements are taken, the motorcycle shall be brought to normal operating temperature. If the motorcycle is fitted with fans with an automatic actuating mechanism, this system shall not be interfered with during the noise measurements. For motorcycles with more than one driven wheel, only the drive provided for normal road operation may be used. Where a motorcycle is fitted with a sidecar, this shall be removed for the purposes of the test.
2.1.3.2.   Test site
The test site shall consist of a central acceleration section surrounded by a substantially flat test area. The acceleration section shall be flat; its surface shall be dry and such that surface noise remains low.
On the test site, the variations in the free sound field between the sound source at the centre of the acceleration section and the microphone shall not exceed 1,0 dB. This condition will be deemed to be met if there are no large objects which reflect sound, such as fences, rocks, bridges or buildings, within 50 m of the centre of the acceleration section. The surface covering of the test site shall conform to the requirements of Appendix 4.
The microphone shall not be obstructed in any way which could affect the sound field, and no person may stand between the microphone and the sound source. The observer carrying out the measurements shall so position himself as not to affect the readings of the measuring instrument.
2.1.3.3.   Miscellaneous
Measurements shall not be taken in poor atmospheric conditions. It shall be ensured that the results are not affected by gusts of wind.
For measurements, the A-weighted sound level of noise sources other than those of the vehicle to be tested and of wind effects shall be at least 10,0 dB(A) below the sound level produced by the vehicle. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the microphone’s sensitivity and directional characteristics.
If the difference between the ambient noise and the measured noise is between 10,0 and 16,0 dB(A), the test results shall be calculated by subtracting the appropriate correction from the readings on the sound-level meter, as in the following graph:

Figure Ap2-1


Difference between ambient noise and noise to be measured




Difference between ambient noise and noise to be measured
2.1.4.   Method of measurement
2.1.4.1.   Nature and number of measurements
The maximum noise level expressed in A-weighted decibels (dB(A)) shall be measured as the motorcycle travels between lines AA′ and BB′ (Figure Ap2-2). The measurement will be invalid if an abnormal discrepancy is recorded between the peak value and the general sound level.
At least two measurements shall be taken on each side of the motorcycle.
2.1.4.2.   Positioning of the microphone
The microphone shall be positioned 7.5 m ± 0.2 m from the reference line CC′ (Figure Ap2-2) of the track and 1.2 m ± 0.1 m above ground level.
2.1.4.3.   Conditions of operation
The motorcycle shall approach line AA′ at an initial steady speed as specified in points 2.1.4.3.1 and 2.1.4.3.2. When the front of the motorcycle reaches line AA′, the throttle shall be fully opened as quickly as practically possible and kept in that position until the rear of the motorcycle reaches line BB′; the throttle shall then be returned as quickly as possible to the idle position.
For all measurements, the motorcycle shall be ridden in a straight line over the acceleration section keeping the longitudinal median plane of the motorcycle as close as possible to line CC′.
2.1.4.3.1.   Motorcycles with non-automatic gearboxes
2.1.4.3.1.1.   Approach speed
The motorcycle shall approach line AA′ at a steady speed






—


of 50 km/h, or










—


corresponding to an engine speed equal to 75 % of the engine speed at which maximum net power is developed,




whichever is the lower.
2.1.4.3.1.2.   Selection of gear ratio
2.1.4.3.1.2.1.   Motorcycles fitted with a gearbox with four ratios or fewer, whatever the cylinder capacity of their engines, shall be tested only in second gear.
2.1.4.3.1.2.2.   Motorcycles fitted with engines with a cylinder capacity not exceeding 175 cm3 and a gearbox with five ratios or more shall be tested only in third gear.
2.1.4.3.1.2.3.   Motorcycles fitted with engines having a cylinder capacity of more than 175 cm3 and a gearbox with five ratios or more shall be tested once in second gear and once in third gear. The result used shall be the average of the two tests.
2.1.4.3.1.2.4.   If, during the test carried out in second gear (see points 2.1.4.3.1.2.1 and 2.1.4.3.1.2.3), the engine speed on the approach to the line marking the end of the test track exceeds 100 % of the engine speed at which maximum net power is developed, the test shall be carried out in third gear and the noise level measured shall be the only one recorded as the test result.
2.1.4.3.2   Motorcycles with automatic gearboxes
2.1.4.3.2.1.   Motorcycles without a manual selector
2.1.4.3.2.1.1.   Approach speed
The motorcycle shall approach line AA′ at steady speeds of 30, 40 and 50 km/h or 75 % of the maximum road speed if that value is lower. The condition giving the highest sound level is chosen.
2.1.4.3.2.2.   Motorcycles equipped with a manual selector with X forward drive positions
2.1.4.3.2.2.1.   Approach speed
The motorcycle shall approach line AA′ at a steady speed of:






—


less than 50 km/h, the engine rotation speed being equal to 75 % of the engine speed at which maximum net power is developed, or










—


50 km/h, the engine rotation speed being less than 75 % of the engine speed at which maximum net power is developed.




If, in the test at a steady speed of 50 km/h, the gears change down to first, the approach speed of the motorcycle may be increased to a maximum of 60 km/h to avoid the downshift.
2.1.4.3.2.2.2.   Position of the manual selector

The vehicle shall approach line AA′ at a steady speed corresponding either to a speed of rotation of the engine equal to three-quarters of that at which the engine develops its maximum power, or to three-quarters of the maximum speed of rotation of the engine permitted by the governor, or 50 km/h, whichever is slowest.
2.2.4.4.2.   Vehicle with manual gearbox
If the vehicle is fitted with a gearbox with two, three or four ratios, second gear shall be used. If the gearbox has more than four ratios, third gear shall be used. If the engine then reaches a speed of rotation beyond its maximum power rating, instead of second or third gear the next higher gear to allow line BB′ on the test track to be reached without exceeding this rating shall be engaged. Overdrive shall not be selected. If the vehicle has a dual-ratio final drive, the ratio selected shall be that corresponding to the highest speed of the vehicle. The vehicle shall approach line AA′ at a steady speed corresponding either to three-quarters of the engine rotation speed at which the engine develops its maximum power, or to three-quarters of the maximum engine rotation speed permitted by the governor, or 50 km/h, whichever is slowest.
2.2.4.4.3.   Vehicle with automatic gearbox
The vehicle shall approach line AA′ at a steady speed of 50 km/h or three-quarters of its maximum speed, whichever is slower. Where several forward drive positions are available, that producing the highest average acceleration of the vehicle between lines AA′ and BB′ shall be selected. The selector position that is used only for braking, manoeuvring or similar slow movements shall not be used.
2.2.4.5.   For hybrid vehicle, the tests shall be performed twice under the following conditions:






(a)


condition A: batteries shall be at their maximum state of charge; if more than one ‘hybrid mode’ is available, the most electric hybrid mode shall be selected for the test;










(b)


condition B: batteries shall be at their minimum state of charge; if more than one ‘hybrid mode’ is available, the most fuel-consuming hybrid mode shall be selected for the test.




2.2.5.   Results (test report)

2.2.5.3.   To take account of inaccuracies, 1,0 dB(A) shall be deducted from each value obtained in accordance with point 2.2.5.2.
2.2.5.4.   If the average of the four measurements does not exceed the maximum permissible level for the category of vehicle in question, the limit laid down in point 2.2.1 will be deemed as being complied with. This average value will constitute the result of the test.
2.2.5.5.   If the average of four results of Condition A and if this average of four results of Condition B do not exceed the maximum permissible level for the category to which the hybrid vehicle being tested belongs, the limits laid down in point 2.2.1 shall be deemed as being complied with.
The highest average value shall be taken as the result of the test.

During the measurements, the gearbox shall be in neutral gear. If it is impossible to disconnect the drive train, the driving wheels of the moped or tricycle shall be allowed to rotate freely, e.g. by placing the vehicle on its centre stand or on rollers.
2.3.3.2.   Test site (see Figure Ap3-3)
Any area in which there are no significant acoustic disturbances may be used as a test site. Flat surfaces which are covered with concrete, asphalt or some other hard material and are highly reflective are suitable; surfaces consisting of earth which has been tamped down shall not be used. The test site shall be in the form of a rectangle the sides of which are at least 3 m from the outer edge of the vehicle (handlebars excluded). There shall be no significant obstacles, e.g. no persons other than the rider and the observer may stand within this rectangle.
The vehicle shall be positioned within the rectangle so that the microphone used for measurement is at least 1 m from any kerb.
2.3.3.3.   Miscellaneous
Instrument readings caused by ambient noise and wind effects shall be at least 10.0 dB(A) lower than the sound levels to be measured. A suitable windshield may be fitted to the microphone provided that account is taken of its effect on the sensitivity of the microphone.

In relation to this vertical plane, the microphone shall be located on the side on which there is the maximum possible distance between the microphone and the outline of the vehicle (handlebars excluded).
If the exhaust system has more than one outlet at centres less than 0,3 m apart, the microphone shall face the outlet which is nearest the vehicle (handlebars excluded) or the outlet which is highest above the surface of the track. If the centres of the outlets are more than 0,3 m apart, separate measurements shall be taken for each of them, the highest figure recorded being taken as the test value.
2.3.4.3.   Operating conditions
The engine speed shall be held steady at:






—


((S)/(2)) if S is more than 5 000 rpm,










—


((3S)/(4)) if S is not more than 5 000 rpm,




where S is the engine speed at which maximum power is developed.
When a constant engine speed is reached, the throttle shall be returned swiftly to the idle position. The noise level shall be measured during an operating cycle consisting of a brief period of constant engine speed and throughout the deceleration period, the maximum meter reading being taken as the test value.
2.3.5.   Results (test report)
2.3.5.1.   The test report drawn up for the purpose of issuing the information document according to the template referred to in Article 27(4) of Regulation (EU) No 168/2013 shall indicate all relevant data and particularly those used in measuring the noise of the stationary vehicle.
2.3.5.2.   Values read off the measuring instrument shall be rounded to the nearest decibel.
If the figure following the decimal point is 5, the total is rounded up.
Only measurements which vary by no more than 2,0 dB(A) in three consecutive tests will be used.
2.3.5.3.   The highest of the three measurements shall be taken as the test result.

Appendix 4

Test track specification

0.   Introduction

This Appendix lays down specifications relating to the physical characteristics and the layout of the test track paving.
1.   Required characteristics of surface

A surface is considered to conform to this Regulation if its texture and void content or noise absorption coefficient have been measured and found to fulfil the requirements of points 1.1 to 1.4 and the design requirements (point 2.2) have been met.
1.1.   Residual void content
The residual void content, Vc, of the test track paving mixture shall not exceed 8 %. The measurement procedure is set out in point 3.1.
1.2.   Noise absorption coefficient
If the surface fails to comply with the residual void content requirement, it is acceptable only if its noise absorption coefficient, α ≤ 0,10. The measurement procedure is set out in point 3.2.
The requirement of points 1.1 and 1.2 is also met if only noise absorption has been measured and found to be: α ≤ 0,10.
1.3.   Texture depth
The texture depth (TD) measured according to the volumetric method (see point 3.3) shall be:
TD ≥ 0,4 mm.
1.4.   Homogeneity of the surface
Every practical effort shall be made to ensure that the surface is as homogenous as possible within the test area. This includes the texture and void content, but it shall be noted that if the rolling process results in more effective rolling in some places than others, the texture may be different and unevenness causing bumps may occur.
1.5.   Period of testing
In order to check whether the surface continues to conform to the texture and void content or noise absorption requirements of this specification, periodic testing of the surface shall be performed at the following intervals:






(a)


for residual void content or noise absorption:






—


when the surface is new; if the surface meets the requirements when new, no further periodical testing is required,










—


if the surface does not meet the requirement when new, it may do so subsequently because surfaces tend to become clogged and compacted with time;














(b)


for texture depth (TD):






—


when the surface is new,










—


when the noise testing starts (NB at least four weeks after laying),










—


every twelve months thereafter.








2.   Test surface design

2.1.   Area
When designing the test track layout, it is important to ensure that, as a minimum requirement, the area traversed by the vehicles running through the test strip is covered with the specified test material with suitable margins for safe and practical driving. This will require that the width of the track is at least 3 m and the length of the track extends beyond lines AA and BB by at least 10 m at either end. Figure Ap4-1 shows a plan of a suitable test site and indicates the minimum area which shall be machine-laid and machine-compacted with the specified test surface material.

Figure Ap4-1


Minimum requirements for test surface area

The shaded part is called ‘test area’
No large acoustically reflective objects within this radus
Min. area covered with test road surface
Microphone (h = 1,2 m)

2.2.   Design requirements for the surface
The test surface shall meet four design requirements:






(a)


it shall be a dense asphaltic concrete;










(b)


the maximum chipping size shall be 8 mm (tolerances allow from 6.3 to 10 mm);










(c)


the thickness of the wearing course shall be ≥ 30 mm;










(d)


the binder shall be a straight penetration-grade bitumen without modification.




As a guide to the test surface constructor, an aggregate grading curve which will give the desired characteristics is shown in Figure Ap4-2. In addition, Table Ap4-1 gives guidelines for obtaining the desired texture and durability. The grading curve fits the following formula:

Equation Ap4-1:






where:






d


square mesh sieve size, in mm




dmax



8 mm for the mean curve




dmax



10 mm for the lower tolerance curve




dmax



6,3 mm for the upper tolerance curve




In addition:






—


the sand fraction (0,063 mm < square mesh sieve size < 2 mm) shall include no more than 55 % natural sand and least 45 % crushed sand,










—


the base and sub-base shall ensure good stability and evenness, according to best road construction practice,










—


the chippings shall be crushed (100 % crushed faces) and of a material with a high resistance to crushing,










—


the chippings used in the mix should be washed,










—


no extra chippings shall be added onto the surface,










—


the binder hardness expressed as PEN value shall be 40 to 60, 60 to 80 or 80 to 100, depending on climatic conditions. As hard a binder as possible shall be used, provided this is consistent with common practice,










—


the temperature of the mix before rolling shall be such as to achieve the required void content by subsequent rolling. In order to satisfy the specifications of points 1.1 to 1.4 as regards compactness, attention shall be paid to an appropriate choice of mixing temperature, an appropriate number of passes and the choice of compacting vehicle.

3.   Test methods

3.1   Measurement of the residual void content
For the purpose of this measurement, cores are taken from at least four different points of the track which are equally distributed in the test area between lines AA and BB (see Figure Ap4-1). In order to avoid creating a lack of homogeneity and unevenness in the wheel tracks, cores shall not be taken in the tracks themselves, but close to them. At least two cores shall be taken close to the wheel tracks and at least one approximately midway between the tracks and each microphone location.
If there is a suspicion that the homogeneity requirement is not met (see point 1.4), cores shall be taken from more points in the test area.
The residual void content must be determined for each core. The average value for all cores is calculated and compared with the requirement of point 1.1. In addition, no single core shall have a void value of over 10 %.
The test surface constructor is reminded that problems may arise where the test area is heated by pipes or electrical wires. Cores shall be taken from this area and such installations shall be carefully planned with respect to future core drilling locations. It is recommended that a few areas of approximately 200 × 300 mm be left where there are no wires or pipes, or where the latter are located deep enough not to be damaged by cores taken from the surface layer.
3.2.   Noise absorption coefficient
The noise absorption coefficient (normal incidence) is measured by the impedance tube method using the procedure specified in ISO 10534-1:1996: ‘Determination of sound absorption coefficient and impedance in impedance tubes – Part 1: Method using standing wave ratio’.
The same requirements apply to test specimens as to residual void content (see point 3.1).
The noise absorption is measured in the range 400 to 800 Hz and in the range 800 to 1 600 Hz (at least at the centre frequencies of third octave bands) and the maximum values shall be identified for both of these frequency ranges. The values for all test scores are averaged to constitute the final result.
3.3.   Volumetric macro texture measurement
Texture depth measurements are taken from at least ten points evenly spaced along the wheel tracks of the test strip and the average value is compared with the specified minimum texture depth. See Annex F to ISO 10844:2011 for a description of the procedure.
4.   Stability in time and maintenance

4.1.   Age influence
It is expected that the tyre/road noise levels measured on the test surface may increase slightly in the first 6 to 12 months after construction.
The surface will achieve its required characteristics at least four weeks after construction.
Stability over time is determined mainly by the polishing and compaction caused by vehicles driving on the surface. It shall be periodically checked as stated in point 1.5.
4.2.   Maintenance of the surface.
Loose debris or dust which could significantly reduce the effective texture depth shall be removed from the surface. Salt may alter the surface temporarily or even permanently in such a way as to increase noise and it is therefore not recommended that it be used for de-icing.
4.3.   Repaving the test area
It is not necessary to repave more than the test strip (3 m wide in Figure Ap4-1) where vehicles are driving provided the area outside the strip met the residual void content or noise absorption requirements when it was measured.
5.   Documentation of the surface and of tests performed on it

5.1.   Documentation of the test surface
The following data shall be given in a document describing the test surface:






(a)


the location of the test track;










(b)


type of binder, binder hardness, type of aggregate, maximum theoretical density of the concrete (‘DR’), thickness of the wearing course and grading curve determined from cores from the test track;

(vi)


the institution responsible for tests (i) and (iii) and the type of equipment used;










(vii)


date of the test(s) and date when the cores were taken from the test track.








5.2.   Documentation of vehicle noise tests
In the document describing the vehicle noise test(s), it shall be stated whether all the requirements were fulfilled or not. Reference shall be made to a document in accordance with point 5.1.

The power correction formula is as follows:

3.2.2.   Dry reference pressure (pso): 99 kPa (990 mbar)
Note: the dry reference pressure is based on a total pressure of 100 kPa and a water vapour pressure of 1 kPa.
3.2.3.   Atmospheric test conditions
3.2.3.1.   During the test, the atmospheric conditions shall lie within the following range:

3.3.1.   Equation Ap2.1-2 applies only if:
0,93 ≤ α1 ≤ 1,07
If the limit values are exceeded, the corrected value obtained and the test conditions (temperature and pressure) shall be stated exactly in the test report.
3.4.   Determination of the correction factor for mechanical efficiency of the transmission α2

Where:

Equation Ap2.1-2:





where nt is the efficiency of the transmission located between the crankshaft and the measuring point.
This transmission efficiency nt is determined from the product (multiplication) of efficiency nj of each of the components of the transmission:

Engine speed tolerance when performing maximum torque and net power measurements: ≤ 3 %


(1)  If it is difficult to use the standard exhaust system, an exhaust system causing an equivalent pressure drop may be fitted for the test with the agreement of the manufacturer. In the test laboratory when the engine is in operation, the exhaust gas extraction system shall not cause in the extraction flue at the point where it is connected to the vehicle’s exhaust system a pressure differing from atmospheric pressure by ± 740 Pa (7,40 mbar), unless, before the test, the manufacturer accepts a higher back pressure.

(3)  Where a fan or blower may be disengaged, the net engine power shall first of all be stated with the fan (or blower) disengaged, followed by the net engine power with the fan (or blower) engaged. Where a fixed electrically or mechanically-operated fan cannot be fitted on the test bench, the power absorbed by that fan shall be determined at the same rotational speeds as those used when the engine power is measured. That power is deducted from the corrected power in order to obtain the net power.

(4)  The thermostat may be locked in the fully open position.

(5)  The radiator, fan, fan nozzle, water pump and thermostat shall, on the test bench, occupy as far as possible the same position relative to each other as if they were on the vehicle.

The tolerances set out in point 4 of Appendix 2.2 shall apply.


(1)  The complete air intake system shall be fitted as provided for the intended application:






—


where there is a risk of an appreciable effect on the engine power,










—


in the case of two-stroke engines,










—


when the manufacturer requests that this should be done. In other cases, an equivalent system may be used and a check should be made to ascertain that the intake pressure does not differ by more than 100 Pa from the limit specified by the manufacturer for a clean air filter.





(2)  The complete air intake system shall be fitted as provided for the intended application:






—


where there is a risk of an appreciable effect on the engine power,










—


in the case of two-stroke engines,










—


when the manufacturer requests that this should be done. In other cases, an equivalent system may be used and a check should be made to ascertain that the intake pressure does not differ by more than 100 Pa from the limit specified by the manufacturer for a clean air filter.





(3)  The complete exhaust system shall be fitted as provided for the intended application:






—


where there is a risk of an appreciable effect on the engine power,










—


in the case of two-stroke engines,










—


when the manufacturer requests that this should be done. In other cases an equivalent system may be installed provided the pressure measured at the exit of the engine exhaust system does not differ by more than 1 000 Pa from that specified by the manufacturer. The exit of the engine exhaust system is defined as a point 150 mm downstream from the termination of the part of the exhaust system mounted on the engine.

The cooling-liquid circulation shall be operated by the engine water pump only. Cooling of the liquid may be produced either by the engine radiator or by an external circuit, provided that the pressure loss of this circuit and the pressure at the pump inlet remain substantially the same as those of the engine cooling system. The radiator shutter, if incorporated, shall be in the open position.
