            COMMISSION DELEGATED REGULATION (EU) 2018/295
of 15 December 2017
         
amending Delegated Regulation (EU) No 44/2014, as regards vehicle construction and general requirements, and Delegated Regulation (EU) No 134/2014, as regards environmental and propulsion unit performance requirements for the approval of two- or three-wheel vehicles and quadricycles


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 Articles 18(3), 21(5)and 23(12) thereof,

Whereas:







(1)


On the basis of the Commission report to the European Parliament and the Council on the comprehensive effect study of the environmental step Euro 5 for L-category vehicles (2) in accordance with Article 23(4) of Regulation (EU) No 168/2013, and taking into account issues encountered by approval authorities and stakeholders in applying Regulation (EU) No 168/2013, Commission Delegated Regulation (EU) No 44/2014 (3) and Commission Delegated Regulation (EU) No 134/2014 (4), certain changes and clarifications should be made in the Delegated Regulations in order to ensure their smooth application.












(2)


In order to ensure effective functioning of the EU type-approval system for L-category vehicles, the technical requirements and test procedures set out in Delegated Regulations (EU) No 44/2014 and (EU) No 134/2014 should be continuously improved and adapted to technical progress.












(3)


Annex IV to Delegated Regulation (EU) No 44/2014 contains the equation to be used for checking compliance of produced vehicles, systems, components and separate technical units with the approved type. The equation should be amended to ensure clarity. Annex XII to Delegated Regulation (EU) No 44/2014 should be amended with respect to the engine operation window for misfire detection to ensure that the imposed requirements are technically feasible. Annex XII should also be amended to enable a technical upgrade to new standards developed for the interface between generic scan tools and the vehicle with respect to the on-board diagnostic (OBD) systems. Appendix 2 to Annex XII should be amended to provide clarification on several items that are monitored with respect to the OBD requirements set out therein. New appendices should be added to Annex XII to ensure the correct implementation of in-use performance ratios.












(4)


Certain equations should be adapted in Annexes II, III and IV to Delegated Regulation (EU) No 134/2014 to provide more clarity. Annex VI to that Delegated Regulation should be amended to ensure the correct application of test requirements regarding the durability of pollution control devices. The classification requirements of the Standard Road Cycle for L-Category Vehicles (SRC-LeCV) in Annex VI should be adapted to ensure the correct application of those requirements during testing. The use of the Approved Mileage Accumulation (AMA) cycle laid down in Annex VI for class III vehicles should be phased out in accordance with the conclusions of the comprehensive environmental effect study. Annex VI should also be amended to allow the use of bench ageing as an alternative to the actual physical durability testing with full or partial mileage accumulation.












(5)


One of the measures against excessive hydrocarbon emissions from L-category vehicles is to limit the evaporative emissions of those vehicles. For that purpose, Annex VI(C) to Regulation (EU) No 168/2013 lays down hydrocarbon mass limits for vehicle categories L3e, L4e, L5e-A, L6e-A and L7e-A. The evaporative emissions of those vehicles are measured at type-approval. One of the requirements of the type IV Sealed House evaporative Emission Determination (SHED) test is either to fit a rapidly aged carbon canister or to apply an additive deterioration factor when fitting a degreened carbon canister. The comprehensive environmental effect study investigated whether or not it was cost beneficial to apply SHED testing to vehicle categories L1e, L2e, L5e-B, L6e-B, L7e-B and L7e-C. As the result of the study demonstrated that that method was not cost beneficial, Annex V to Delegated Regulation (EU) No 134/2014 should be amended to allow the continuous use of the already established alternative and more cost beneficial method of permeation testing in the Euro 5 step for manufactures of category L1e, L2e, L5e-B, L6e-B, L7e-B and L7e-C vehicles.












(6)


On the basis of the comprehensive environmental effect study, the Commission concluded that the mathematical procedure for the verification of durability requirements set out in Article 23(3) of Regulation (EU) No 168/2013 should be phased out by 2025. The study pointed out that that theoretical procedure did not ensure that the durability requirements set out in Regulation (EU) No 168/2013 were met in reality. To mitigate the impact of phasing out that method, the study proposed to introduce bench ageing as an alternative procedure to the actual durability testing procedure with full mileage and partial mileage accumulation. Bench ageing is a well-established procedure often applied to vehicles falling within the scope Directive 2007/46/EC of the European Parliament and of the Council (5). Annex VI to Delegated Regulation (EU) No 134/2014 should be amended to introduce the bench ageing procedure derived from the requirements set out in Commission Regulation (EC) No 692/2008 (6) and UNECE Regulation No 83 (7) and adapted to fit the requirements needed for L-category vehicles.












(7)


Delegated Regulation (EU) No 44/2014 and Delegated Regulation (EU) No 134/2014 should be amended at the same time to ensure that the Euro 5 step can be correctly implemented for all the L-category vehicles concerned as laid down in the table of Annex IV to Regulation (EU) No 168/2013.












(8)


Delegated Regulation (EU) No 44/2014 and Delegated Regulation (EU) No 134/2014 should therefore be amended accordingly,

3.   Selection of vehicles for IUPR M
3.1.   The manufacturer's sampling shall be drawn from at least two Member States with substantially different vehicle operating conditions (unless only made available on the market in one Member State). Factors such as differences in fuels, ambient conditions, average road speeds, and urban/highway driving split shall be taken into consideration in the selection of the Member States.
For IUPR M testing, only vehicles fulfilling the criteria of point 2.3 of Appendix 4 shall be included in the test sample.
3.2.   In selecting the Member States for sampling vehicles, the manufacturer may select vehicles from a Member State that is considered to be particularly representative. In this case, the manufacturer shall demonstrate to the approval authority which granted the type approval that the selection is representative (e.g. by the market having the largest annual sales of a vehicle family within the Union). When a family requires more than one sample lot to be tested as defined in point 3.3, the vehicles in the second and third sample lots shall reflect different vehicle operating conditions from those selected for the first sample.
3.3.   Sample size
3.3.1.   The number of sample lots shall depend on the annual sales volume of an OBD family in the Union, as defined in the following table:






EU registrations






—


per calendar year (for tailpipe emissions tests)










—


of vehicles of an OBD family with IUPR in the sampling period






Number of sample lots




up to 100 000 


1




100 001  to 200 000 


2




above 200 000 


3




3.3.2.   For IUPR, the number of sample lots to be taken is described in the table in point 3.3.1. and is based on the number of vehicles of an IUPR family that are approved with IUPR
For the first sampling period of an IUPR family, all of the vehicle types in the family that are approved with IUPR shall be considered to be subject to sampling. For subsequent sampling periods, only vehicle types which have not been previously tested or are covered by emissions approvals that have been extended since the previous sampling period shall be considered to be subject to sampling.
For families consisting of fewer than 5 000 EU registrations that are subject to sampling within the sampling period the minimum number of vehicles in a sample lot is six. For all other families, the minimum number of vehicles in a sample lot to be sampled is fifteen.
Each sample lot shall adequately represent the sales pattern, i.e. at least high volume vehicle types (≥ 20 % of the family total) shall be represented.
Vehicles of small series productions with less than 1 000 vehicles per OBD family are exempted from minimum IUPR requirements as well as the requirement to demonstrate these to the type approval authority.
4.   On the basis of the audit referred to in Section 2 the approval authority shall adopt one of the following decisions and actions:






(a)


decide that the IUPR family is satisfactory and not take any further action;










(b)


decide that the data provided by the manufacturer is insufficient to reach a decision and request additional information or test data from the manufacturer;










(c)


decide that based on data from the approval authority or Member State surveillance testing programmes, that information provided by the manufacturer is insufficient to reach a decision and request additional information or test data from the manufacturer;










(d)


decide that the outcome of the audit for the IUPR family is unsatisfactory and proceed to have such vehicle type or IUPR family tested in accordance with Appendix 1.




If according to the IUPR M audit the test criteria of point 3.2. of Appendix 4 are met for the vehicles in a sample lot, the type-approval authority must take the further action described in point (d) of this point.
4.1.   The approval authority, in cooperation with the manufacturer, shall select a sample of vehicles with sufficient mileage whose use under normal conditions can be reasonably assured. The manufacturer shall be consulted on the choice of the vehicles in the sample and allowed to attend the confirmatory checks of the vehicles.

Bench ageing durability test

1.   Bench ageing durability test
1.1   The vehicle tested according the procedure laid down in this appendix has driven more than 100 accumulated kilometres after it was first started at the end of the production line.
1.2.   The fuel used during the test shall be the one of the specified fuels in Appendix 2 of Annex II.
2.   Procedure for Vehicles with Positive Ignition Engines
2.1.   The following bench ageing procedure shall be applicable for positive-ignition vehicles including hybrid vehicles which use a catalyst as the principle after-treatment emission control device.
The bench ageing procedure requires the installation of the catalyst-plus-oxygen sensor system on a catalyst ageing bench.
Ageing on the bench shall be conducted by following the standard bench cycle (SBC) for the period of time calculated from the bench ageing time (BAT) equation. The BAT equation requires, as input, catalyst time-at-temperature data measured during the Standard Road Cycle (SRC-LeCV) described in Appendix 1. As an alternative, if applicable, the catalyst time-at-temperature data measured during the AMA durability cycle, as described in Appendix 2, may be used.
2.2.   Standard bench cycle (SBC). Standard catalyst bench ageing shall be conducted following the SBC. The SBC shall be run for the period of time calculated from the BAT equation. The SBC is described in Appendix 4.
2.3.   Catalyst time-at-temperature data. Catalyst temperature shall be measured during at least two full cycles of the SRC-LeCV cycle as described in Appendix 1, or if applicable at least two full cycles of AMA as described in Appendix 2.
Catalyst temperature shall be measured at the highest temperature location in the hottest catalyst on the test vehicle. Alternatively, the temperature may be measured at another location providing that it is adjusted to represent the temperature measured at the hottest location using good engineering judgement.
Catalyst temperature shall be measured at a minimum rate of one hertz (one measurement per second).
The measured catalyst temperature results shall be tabulated into a histogram with temperature groups of no larger than 25 °C.
2.4.   Bench-ageing time. Bench ageing time shall be calculated using the bench ageing time (BAT) equation as follows:





te for a temperature bin = the ((R/Tr) – (R/Tv))









Total te = Sum of te over all the temperature groups









bench ageing time = A (Total te)




Where:







A


=


1,1 This value adjusts the catalyst ageing time to account for deterioration from sources other than thermal ageing of the catalyst.




R


=


Catalyst thermal reactivity = 18 500 




th


=


The time (in hours) measured within the prescribed temperature bin of the vehicle's catalyst temperature histogram adjusted to a full useful life basis e.g., if the histogram represented 400 km, and useful life is, in accordance with Annex VII to Regulation (EU) No 168/2013, for example for Le3 20 000  km; all histogram time entries would be multiplied by 50 (20 000 /400).




Total te


=


The equivalent time (in hours) to age the catalyst at the temperature of Tr on the catalyst ageing bench using the catalyst ageing cycle to produce the same amount of deterioration experienced by the catalyst due to thermal deactivation over the use for live distance specific for the vehicle class in Annex VII to Regulation (EU) No 168/2013, for example for Le3 20 000  km




te for a temperature bin


=


The equivalent time (in hours) to age the catalyst at the temperature of Tr on the catalyst ageing bench using the catalyst ageing cycle to produce the same amount of deterioration experienced by the catalyst due to thermal deactivation at the temperature bin of Tv over the use for live distance specific for the vehicle class in Annex VII to Regulation (EU) No 168/2013, for example for Le3 20 000  km




Tr


=


The effective reference temperature (in °K) of the catalyst on the catalyst bench run on the bench ageing cycle. The effective temperature is the constant temperature that would result in the same amount of ageing as the various temperatures experienced during the bench ageing cycle.




Tv


=


The mid-point temperature (in °K) of the temperature bin of the vehicle on-road catalyst temperature histogram.




2.5.   Effective reference temperature on the standard bench cycle (SBC). The effective reference temperature of the SBC shall be determined for the actual catalyst system design and actual ageing bench which will be used using the following procedures:






(a)


Measure time-at-temperature data in the catalyst system on the catalyst ageing bench following the SBC. Catalyst temperature shall be measured at the highest temperature location of the hottest catalyst in the system. Alternatively, the temperature may be measured at another location providing that it is adjusted to represent the temperature measured at the hottest location.
Catalyst temperature shall be measured at a minimum rate of one hertz (one measurement per second) during at least 20 minutes of bench ageing. The measured catalyst temperature results shall be tabulated into a histogram with temperature groups of no larger than 10 °C.










(b)


The BAT equation shall be used to calculate the effective reference temperature by iterative changes to the reference temperature (Tr) until the calculated ageing time equals or exceeds the actual time represented in the catalyst temperature histogram. The resulting temperature is the effective reference temperature on the SBC for that catalyst system and ageing bench.




2.6.   Catalyst ageing bench. The catalyst ageing bench shall follow the SBC and deliver the appropriate exhaust flow and emission level in line with the exhaust flow of engine for which the catalyst is designed, exhaust constituents, and exhaust temperature at the face of the catalyst.
All bench ageing equipment and procedures shall record appropriate information (such as measured A/F ratios and time-at-temperature in the catalyst) to assure that sufficient ageing has actually occurred.
2.7.   Required testing. For calculating deterioration factors at least two Type 1 tests before bench ageing of the emission control hardware and at least two Type 1 tests after the bench-aged emission hardware is reinstalled have to be performed on the test vehicle.
Calculation of the deterioration factors has to be done in accordance with the calculation method as specified below.
A multiplicative exhaust emission deterioration factor shall be calculated for each pollutant as follows:





Where:







Mi1



=


mass emission of the pollutant i in g/km after the type 1 test of a vehicle specified in point 1.1. of this Appendix.




Mi2



=


mass emission of the pollutant i in g/km after the type test 1 of an aged vehicle according the procedure described in this Annex.




These interpolated values shall be carried out to a minimum of four places to the right of the decimal point before dividing one by the other to determine the deterioration factor. The result shall be rounded to three places to the right of the decimal point.
If a deterioration factor is less than one, it is deemed to be equal to one.
At the request of a manufacturer, an additive exhaust emission deterioration can be used, the factor shall be calculated for each pollutant as follows:
D. E. F. = Mi2 – Mi1





‘Appendix 4

Standard bench cycle (SBC)

1.   Introduction
The standard ageing durability procedure consists of ageing a catalyst/oxygen sensor system on an ageing bench which follows the standard bench cycle (SBC) described in this Appendix. The SBC requires use of an ageing bench with an engine as the source of feed gas for the catalyst. The SBC is a 60-second cycle which is repeated as necessary on the ageing bench to conduct ageing for the required period of time. The SBC is defined based on the catalyst temperature, engine air/fuel (A/F) ratio, and the amount of secondary air injection which is added in front of the first catalyst.
2.   Catalyst temperature control
2.1.   Catalyst temperature shall be measured in the catalyst bed at the location where the highest temperature occurs in the hottest catalyst. Alternatively, the feed gas temperature may be measured and converted to catalyst bed temperature using a linear transform calculated from correlation data collected on the catalyst design and ageing bench to be used in the ageing process.
2.2.   Control the catalyst temperature at stoichiometric operation (1 to 40 seconds on the cycle) to a minimum of 800 °C (± 10 °C) by selecting the appropriate engine speed, load, and spark timing for the engine. Control the maximum catalyst temperature that occurs during the cycle to 890 °C (± 10 °C) by selecting the appropriate A/F ratio of the engine during the ‘rich’ phase described in the table below.
2.3.   If a low control temperature other than 800 °C is utilized, the high control temperature shall be 90 °C higher than the low control temperature.

3.   Ageing bench equipment and procedures
3.1.   Ageing bench configuration. The ageing bench shall provide the appropriate exhaust flow rate, temperature, air-fuel ratio, exhaust constituents and secondary air injection at the inlet face of the catalyst.
The standard ageing bench consists of an engine, engine controller, and engine dynamometer. Other configurations may be acceptable (e.g. whole vehicle on a dynamometer, or a burner that provides the correct exhaust conditions), as long as the catalyst inlet conditions and control features specified in this Appendix are met.
A single ageing bench may have the exhaust flow split into several streams providing that each exhaust stream meets the requirements of this appendix. If the bench has more than one exhaust stream, multiple catalyst systems may be aged simultaneously.
3.2.   Exhaust system installation. The entire catalyst(s)-plus-oxygen sensor(s) system, together with all exhaust piping which connects these components, will be installed on the bench. For engines with multiple exhaust streams, each bank of the exhaust system will be installed separately on the bench in parallel.
For exhaust systems that contain multiple in-line catalysts, the entire catalyst system including all catalysts, all oxygen sensors and the associated exhaust piping will be installed as a unit for ageing. Alternatively, each individual catalyst may be separately aged for the appropriate period of time.
3.3.   Temperature measurement. Catalyst temperature shall be measured using a thermocouple placed in the catalyst bed at the location where the highest temperature occurs in the hottest catalyst. Alternatively, the feed gas temperature just before the catalyst inlet face may be measured and converted to catalyst bed temperature using a linear transform calculated from correlation data collected on the catalyst design and ageing bench to be used in the ageing process. The catalyst temperature shall be stored digitally at the speed of 1 hertz (one measurement per second).
3.4.   Air/Fuel measurement. Provisions shall be made for the measurement of the air/fuel (A/F) ratio (such as a wide-range oxygen sensor) as close as possible to the catalyst inlet and outlet flanges. The information from these sensors shall be stored digitally at the speed of 1 hertz (one measurement per second).
3.5.   Exhaust flow balance. Provisions shall be made to assure that the proper amount of exhaust (measured in grams/second at stoichiometry, with a tolerance of ± 5 grams/second) flows through each catalyst system that is being aged on the bench.
The proper flow rate is determined based upon the exhaust flow that would occur in the original vehicle's engine at the steady state engine speed and load selected for the bench ageing in point 3.6.
3.6.   Setup. The engine speed, load, and spark timing are selected to achieve a catalyst bed temperature of 800 °C (± 10 °C) at steady-state stoichiometric operation.
The air injection system is set to provide the necessary air flow to produce 3,0 % oxygen (± 0,1 %) in the steady-state stoichiometric exhaust stream just in front of the first catalyst. A typical reading at the upstream A/F measurement point (required in point 5) is lambda 1,16 (which is approximately 3 % oxygen).
With the air injection on, set the ‘Rich’ A/F ratio to produce a catalyst bed temperature of 890 °C (± 10 °C). A typical A/F value for this step is lambda 0,94 (approximately 2 % CO).
3.7.   Ageing cycle. The standard bench ageing procedures use the standard bench cycle (SBC). The SBC is repeated until the amount of ageing calculated from the bench ageing time (BAT) equation is achieved.
3.8.   Quality assurance. The temperatures and A/F ratio in points 3.3. and 3.4. shall be reviewed periodically (at least every 50 hours) during ageing. Necessary adjustments shall be made to assure that the SBC is being appropriately followed throughout the ageing process.
After the ageing has been completed, the catalyst time-at-temperature collected during the ageing process shall be tabulated into a histogram with temperature groups of no larger than 10 °C. The BAT equation and the calculated effective reference temperature for the ageing cycle in accordance with point 2.4. of Appendix 3 to Annex VI will be used to determine if the appropriate amount of thermal ageing of the catalyst has in fact occurred. Bench ageing will be extended if the thermal effect of the calculated ageing time is not at least 95 % of the target thermal ageing.
3.9.   Startup and shutdown. Care should be taken to assure that the maximum catalyst temperature for rapid deterioration (e.g., 1 050 °C) does not occur during startup or shutdown. Special low temperature startup and shutdown procedures may be used to alleviate this concern.
4.   Experimentally determining the R-factor for bench ageing durability procedures
4.1.   The R-factor is the catalyst thermal reactivity coefficient used in the bench ageing time (BAT) equation. Manufacturers may determine the value of R experimentally using the following procedures.
4.2.   Using the applicable bench cycle and ageing bench hardware, age several catalysts (minimum of 3 of the same catalyst design) at different control temperatures between the normal operating temperature and the damage limit temperature. Measure emissions (or catalyst inefficiency (1-catalyst efficiency)) for each exhaust constituent. Assure that the final testing yields data between one- and two-times the emission standard.
4.3.   Estimate the value of R and calculate the effective reference temperature (Tr) for the bench ageing cycle for each control temperature in accordance with point 2.4 of Appendix 3 to Annex VI.
4.4.   Plot emissions (or catalyst inefficiency) versus ageing time for each catalyst. Calculate the least-squared best-fit line through the data. For the data set to be useful for this purpose the data should have an approximately common intercept [between 0 and 6 400 km. See the following graph for an example.]
4.5.   Calculate the slope of the best-fit line for each ageing temperature.
4.6.   Plot the natural log (ln) of the slope of each best-fit line (determined in point 4.5) along the vertical axis, versus the inverse of ageing temperature (1/(ageing temperature, deg K)) along the horizontal axis, Calculate the least squared best-fit lines through the data. The slope of the line is the R-factor. See the following graph for an example

4.7.   Compare the R-factor to the initial value that was used in accordance with point 4.3. If the calculated R-factor differs from the initial value by more than 5 %, choose a new R-factor that is between the initial and calculated values, and then repeat steps of point 4,, to derive a new R-factor. Repeat this process until the calculated R-factor is within 5 % of the initially assumed R-factor.
4.8.   Compare the R-factor determined separately for each exhaust constituent. Use the lowest R-factor (worst case) for the BAT equation.
