For example the measuring point at ‘A’ which is for the 90 % full load line and 100 % rated speed applies to the rated power/speed area bounded by ABCD on the diagram.

| 2.3 | If the test is a bench test the engine shall be disconnected from the brake, the latter being replaced either by the rotating parts driven when no gear is engaged or by an inertia substantially equivalent to that of the said parts (see paragraph 7.3 of Annex 1 to this Regulation). |

| 2.6 | The operation described in paragraph 2.5 shall be repeated not less than six times in order to clear the exhaust system and to allow for any necessary adjustment of the apparatus. The maximum opacity values read in each successive acceleration shall be noted until stabilised values are obtained. No account shall be taken of the values read while, after each acceleration, the engine is idling. The values read shall be regarded as stabilised when four of them consecutively are situated within a band width of 0,25 m-1 and do not form a decreasing sequence. The absorption coefficient XM to be recorded shall be the arithmetical mean of these four values. |

| --- | --- |

2.7.1

| 2.7.2 | in cases where the engine has several exhaust outlets, the tests shall be carried out with all the outlets joined in an adequate device ensuring mixture of the gases and ending in a single orifice. Free acceleration tests, however, may be carried out on each outlet. In this case the value to be used for calculating the correction to the absorption coefficient shall be the arithmetical mean of the values recorded at each outlet, and the test shall be regarded as valid only if the extreme values measured do not differ by more than 0,15 m-1. |

Note 1: Equivalent ISO methods will be referred to when issued for all properties listed above.

Note 2: The figures quoted show the total evaporated quantities (% recovered + % loss).

Note 3: This fuel may be based on straight run and cracked distillates; desulphurisation is allowed. It must not contain any metallic additives.

Note 4: The values quoted in the specification are ‘true values’. In establishment of their limit values the terms of ASTM D 3244 ‘Defining a Basis for Petroleum Product Quality Disputes’ have been applied and, in fixing a maximum value, a minimum difference of 2R above zero has been taken into account; in fixing a maximum and minimum value, the minimum difference is 4R (R = Reproducibility). Notwithstanding this measure, which is necessary for statistical reasons, the manufacturer of a fuel should nevertheless aim at a zero value where the stipulated maximum value is 2R and at the mean value in the case of quotations of maximum and minimum limits. Should it be necessary to clarify the question as to whether a fuel meets the requirements of the specification, the terms of ASTM D 3244 should be applied.

Note 5: If it is required to calculate the thermal efficiency of an engine or vehicle, the calorific value of the fuel can be calculated from: specific energy (calorific value) (net)

MJ/kg = (46,423 - 8,792 d2 +3,170 d)

(1 — (x + y + s)) +9,420 s -2,499 x where:

d is the density at 15 °C

x is the proportion by mass of water (% divided by 100)

y is the proportion by mass of ash (% divided by 100)

s is the proportion by mass of sulphur (% divided by 100).

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.

(2)  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

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

(4)  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

(5)  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 defined in paragraph 6.2, should be deducted from the corrected power.

(6)  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.

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

(8)  Minimum power of the generators 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

(9)  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

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

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

(4)  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).

5.   POWER CORRECTION FACTORS

5.1.   Definition

The power correction factor is the coefficient α to determine the engine power under the reference atmospheric conditions specified in paragraph 5.2.

where Po = α · P

Po is the corrected power (i.e. power under reference atmospheric conditions)

α is the correction factor (αa or αd)

P is the measured power (test power)

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 |

80 kPa ≤ Ps ≤ 110 kPa

5.4.   Determination of correction factor αa and αd (1)

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

  The correction factor αa is obtained by applying the formula:




   (2)

  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. |

   (2)

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

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

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.

5.4.2.1.2.

Formula

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):

| | where there is a risk of an appreciable effect on the engine power; |
| --- | --- |

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

| | in the case of two-stroke and positive-ignition engines; |
| --- | --- |

in the case of two-stroke and positive-ignition engines;

| | when the manufacturer requests that this should be done. |
| --- | --- |

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.

(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; |
| --- | --- |

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

| | in the case of two-stroke and positive-ignition engines; |
| --- | --- |

in the case of two-stroke and positive-ignition engines;

| | when the manufacturer requests that this should be done. |
| --- | --- |

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.

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

(3)  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).

(4)  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.

(5)  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 defined in paragraph 6.2, should be deducted from the corrected power.

(6)  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.

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

(8)  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.

(9)  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.

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

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

(2)  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).

Cooling of the liquid may be produced either by the drive train 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 drive train cooling system. The radiator shutter, if any, shall be in the open position.

Where the fan, radiator and fan cowl cannot conveniently be fitted for the bench test, the power absorbed by the fan when separately mounted in its correct position in relation to the radiator and cowl (if used) shall be determined at the speed corresponding to the motor speeds used for measurement of the motor power either by calculation from standard characteristics or by practical tests. This power, corrected to the standard atmospheric conditions, should be deducted from the correct power.

(2)  Where a disconnectable or progressive fan or blower is incorporated, the test should be carried out with the disconnectable fan (or blower) disconnected or at maximum slip condition.

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

ANNEX 7

CHECKS ON CONFORMITY OF PRODUCTION

1.   GENERAL

These requirements are consistent with tests to be held to check conformity of production, according to paragraph 6.3.6.

2.   TEST PROCEDURES

The methods of testing and measuring instruments shall be those described in Annexes 5 or 6 to this Regulation.

3.   COLLECTION OF SAMPLES

One drive train has to be chosen. If after the test of paragraph 5.1, the drive train is not considered as conforming to the requirements of this Regulation, two more drive trains have to be tested.

4.   MEASUREMENT CRITERIA

4.1.   Net power of internal combustion engine

During the tests to verify conformity of production, the power shall be measured at two engine speeds S1 and S2, corresponding respectively to the measurement points of maximum power and maximum torque accepted for type approval. At these two engine speeds, which are subject to a tolerance of ± 5 %, the net power measured at least one point within the ranges S1 ± 5 % and S2 ± 5 % shall not differ by more than ± 5 % from the approval figure.

4.2.   Net power and maximum 30 minutes power of electric drive trains

During the tests to verify conformity of production the power shall be measured at motor speed S1 corresponding to the measurement point of maximum power accepted for type approval. At this speed, the net power shall not differ by more than ± 5 % from the approval figure.

5.   EVALUATION OF RESULTS

| 5.1. | If the net power and the maximum 30 minutes power of the drive train tested pursuant to paragraph 2 fulfils the requirement of paragraph 4, the production is considered to conform to the type approval. |
| --- | --- |

5.1.

| 5.2. | If the requirements of paragraph 4 are not fulfilled, two more drive trains are tested in the same way. |
| --- | --- |

5.2.

| 5.3. | If the net power figure or the maximum 30 minutes power of the second and/or third drive train of paragraph 5.2 does not fulfil the requirements of paragraph 4 above, the production shall be considered not to conform to the requirements of this Regulation and the provisions of paragraph 7.1 shall be put into effect. |

(*1)  Value to be determined at standard conditions (293,2 K (20 °C) and 101,3 kPa).

(*2)  This method may not accurately determine the presence of corrosive materials if the sample contains corrosion inhibitors or other chemicals which diminish the corrosivity of the sample to the copper strip. Therefore, the addition of such compounds for the sole purpose of biasing the test method is prohibited.

(*3)  Based on the gross calorific value and calculated for 0 °C.

The constituting gases of the mixtures shall have at least the following purities:

| N2 | : | 99 % |
| --- | --- | --- |
| CH4 | : | 95 % with a total content of hydrogen, carbon monoxide and oxygen below 1 % and a total content of nitrogen and carbon dioxide below 2 %. |

The Wobbe index is the ratio of the calorific value of a gas per unit volume and the square root of its relative density under the same reference conditions:

Formula

with Hgas
  = calorific value of the fuel in MJ/m3 at 0 °C

air= density of air at 0 °C

gas= density of fuel at 0 °C

The Wobbe index is said to be gross or net according to whether the calorific value uses is the gross or net calorific value.
