The supply voltage of the test shall be given by the vehicle manufacturer.







Note:



If the battery limits the maximum 30 minutes power, the maximum 30 minutes power of an electric vehicle can be less than the maximum 30 minutes power of the drive train of the vehicle according to this test.




5.3.1.   Determination of the net power








5.3.1.1.


The motor and its entire equipment assembly must be conditioned at a temperature of 25 °C ± 5 °C for a minimum of two hours.












5.3.1.2.


The net power test shall consist of a run at full setting of the power controller.












5.3.1.3.


Just before beginning the test, the motor shall be run on the bench for three minutes delivering a power equal to 80 per cent of the maximum power at the speed recommended by the manufacturer.












5.3.1.4.


Measurements shall be taken at a sufficient number of motor speeds to define correctly the power curve between zero and the highest motor speed recommended by the manufacturer. The whole test shall be completed within 5 minutes.




5.3.2.   Determination of the maximum 30 minutes power








5.3.2.1.


The motor and its entire equipment assembly must be conditioned at a temperature of 25 °C ± 5 °C for a minimum of four hours.












5.3.2.2.


The electric drive train shall run at the bench at a power which is the best estimate of the manufacturer for the maximum 30 minutes power. The speed must be in a speed range, which the net power is greater than 90 per cent of the maximum power as measured in paragraph 5.3.1. This speed shall be recommended by the manufacturer.












5.3.2.3.


Speed and power shall be recorded. The power must be in a range of ± 5 per cent of the power value at the start of the test. The maximum 30 minutes power is the average of the power within the 30 minutes period.




5.4.   Interpretation of results
The net power and the maximum 30 minutes power for electric drive trains indicated by the manufacturer for the type of drive train shall be accepted if it does not differ by more than ± 2 per cent for maximum power and more than ± 4 per cent at the other measurement points on the curve with a tolerance of ± 2 per cent for engine or motor speed, or within the engine or motor speed range (X1 min–1 + 2 per cent) to (X2 min–1 – 2 per cent) (X1 < X2) from the values measured by the technical service on the drive train submitted for testing.
In case of a dual-fuel engine, the net power indicated by the manufacturer shall be the one measured on the dual-fuel mode of that engine.
6.   CONFORMITY OF PRODUCTION
The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324 — E/ECE/TRANS/505/Rev.2), with the following requirements:

3.2.


Data to be recorded are those indicated in paragraph 4 of the appendix to this annex. Performance data shall be obtained under stabilized operating conditions with an adequate fresh air supply to the engine. Combustion chambers may contain deposits, but in limited quantity. Test conditions, such as inlet air temperature, shall be selected as near to reference conditions (see paragraph 5.2 of this annex) as possible in order to minimize the magnitude of the correction factor.












3.3.


The temperature of the inlet air to the engine (ambient air) shall be measured within 0,15 m upstream of the point of entry to the air cleaner, or, if no air cleaner is used, within 0,15 m of the air inlet horn. The thermometer or thermocouple shall be shielded from radiant heat and placed directly in the air stream. It shall also be shielded from fuel spray-back. A sufficient number of locations shall be used to give a representative average inlet temperature.












3.4.


No data shall be taken until torque, speed and temperatures have been maintained substantially constant for at least one minute.












3.5.


The engine speed during a run or reading shall not deviate from the selected speed by more than ± 1 per cent or ± 10 min–1, whichever is greater.












3.6.


Observed brake load, fuel consumption and inlet air temperature data shall be taken simultaneously and shall be the average of two stabilized consecutive values which do not vary more than 2 per cent for the brake load and fuel consumption.












3.7.


The temperature of the coolant at the outlet from the engine shall be kept at the value specified by the manufacturer. If no temperature is specified by the manufacturer, the temperature shall be 353 K ± 5 K. For air-cooled engines, the temperature at a point indicated by the manufacturer shall be kept within 

 of the maximum value specified by the manufacturer in the reference conditions.












3.8.


The fuel temperature shall be measured at the inlet to the carburettor or at the fuel injection system and maintained within the limits established by the engine manufacturer.

5.   POWER CORRECTION FACTORS
5.1.   Definition
The power correction factor is the coefficient L determine the engine power under the reference atmospheric conditions specified in paragraph 5.2 below.
Where





Po is the corrected power (i.e. power under reference atmospheric conditions)
L is the correction factor (La or Ld)
P is the measured power (test power)
5.2.   Reference atmospheric conditions
5.2.1.   Temperature (To): 298 K (25 °C)
5.2.2.   Dry pressure (Pso): 99 kPa

Note: The dry pressure is based on a total pressure of 100 kPa and a water vapour pressure of 1 kPa.
5.3.   Test atmospheric conditions
The atmospheric conditions during the test shall be the following:
5.3.1.   Temperature (T)






For positive-ignition engines


288 K ≤ T ≤ 308 K




For diesel engines


283 K ≤ T ≤ 313 K




5.3.2.   Pressure (Ps)
80 kPa ≤ Ps ≤ 110 kPa
5.4.   Determination of correction factor αa and αd (10)

5.4.1.   Naturally aspirated or pressure-charged positive-ignition engine factor αa

The correction factor αa is obtained by applying the formula:




                      (11)

Where
Ps is the total dry atmospheric pressure in kilopascals (kPa); that is to say, the total barometric pressure minus water vapour pressure
T is the absolute temperature in kelvins (K) of the air drawn in by the engine.
Conditions to be complied with in the laboratory
For a test to be valid, the correction factor αa must be such that 0,93 ≤ αa ≤ 1,07
If these limits are exceeded, the corrected value obtained shall be given and the test conditions (temperature and pressure) precisely stated in the test report.
5.4.2.   Diesel engines — Factor αd

The power correction factor (αd) for diesel engines at constant fuel rate is obtained by applying the formula:
Where αd = (fa) fm

fa is the atmospheric factor
fm is the characteristic parameter for each type of engine and adjustment
5.4.2.1.   Atmospheric factor fa

This factor indicates the effects of environmental conditions (pressure, temperature and humidity) on the air drawn in by the engine. The atmospheric factor formula differs according to the type of engine.
5.4.2.1.1.   Naturally aspirated and mechanically supercharged engines





5.4.2.1.2.   Turbocharged engines with or without cooling of inlet air





5.4.2.2.   Engine factor fm

fm is a function of qc (fuel flow corrected) as follows:
fm = 0,036 qc – 1,14
Where: qc = q/r
Where:
q is the fuel flow in milligram per cycle per litre of total swept volume (mg/(l.cycle))
r is the pressure ratio of compressor outlet and compressor inlet (r = 1 for naturally aspirated engines)
This formula is valid for a value interval of qc included between 40 mg/(l.cycle) and 65 mg/(l.cycle.)
For qc values lower than 40 mg/(l.cycle), a constant value of fm equal to 0,3 (fm = 0,3) will be taken.
For qc values higher than 65 mg/(l.cycle), a constant value of fm equal to 1,2 (fm = 1,2) will be taken (see figure):





5.4.2.3.   Conditions to be complied with in the laboratory
For a test to be valid; the correction factor αd must be such that 0,9 ≤ αd ≤ 1,1
If these limits are exceeded, the corrected value obtained shall be given and the test conditions (temperature and pressure) precisely stated in the test report.

(1a)


The complete 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 and positive-ignition 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)  






(1b)


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 and positive-ignition 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 from 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.





(1)  If an exhaust brake is incorporated in the engine, the throttle valve must be fixed in a fully open position.

(2)  The fuel feed pressure may be adjusted, if necessary, to reproduce the pressures existing in the particular engine application (particularly when a ‘fuel return’ system is used).

(3)  The air intake valve is the control valve for the pneumatic governor of the injection pump. The governor of the fuel injection equipment may contain other devices which may affect the amount of injected fuel.

(4)  The radiator, the fan, the fan cowl, the water pump and the thermostat shall be located on the test bench in the same relative positions as on the vehicle. 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.
Where the fan, radiator and cowl system cannot conveniently be fitted to the engine, the power absorbed by the fan when separately mounted in its correct position in relation to the radiator and cowl (if used), must be determined at the speeds corresponding to the engine speeds used for measurement of the engine power either by calculation from standard characteristics or by practical tests. This power, corrected to the standard atmospheric conditions (293,2 K (20 °C) and 101,3 kPa), should be deducted from the corrected power.

(5)  Where a disconnectable or progressive fan or blower is incorporated, the test shall be made with the disconnectable fan (or blower) disconnected or with the progressive fan or blower running at maximum slip.

(6)  The thermostat may be fixed in the fully open position.

(7)  Minimum power of the generator: the power of the generator shall be limited to that necessary for the operation of accessories which are indispensable for the operation of the engine. If the connection of a battery is necessary, a fully charged battery in good order must be used.

(8)  Charge air cooled engines shall be tested with charge air cooling, whether liquid or air cooled, but if the engine manufacturer prefers, a test bench system may replace the air cooled cooler. In either case, the measurement of power at each speed shall be made with the same pressure drop and temperature drop of the engine air across the charge air cooler on the test bench system as those specified by the manufacturer for the system on the complete vehicle.

(9)  They may include, for example, EGR (Exhaust gas recirculation) system, catalytic convertor, thermal reactor, secondary air supply system and fuel evaporation protecting system.

(10)  The tests may be carried out in air-conditioned test rooms where the atmospheric conditions may be controlled.

(11)  In the case of engines fitted with automatic air temperature control, if the device is such that at full load at 25 °C no heated air is added, the test shall be carried out with the device fully closed. If the device is still operating at 25 °C then the test is made with the device operating normally and the exponent of the temperature term in the correction factor shall be taken as zero (no temperature correction).
