            ANNEX 4
            
               METHOD FOR MEASURING INTERNAL COMBUSTION ENGINE NET POWER
            
            1.   These provisions apply to the method for determining the power curve at full load of an internal combustion engine operated under intermittent speed as a function of engine speed and the rated speed and rated net power of an internal combustion engine under constant speed.
            2.   Test conditions
            2.1.   The engine shall have been run-in according to the manufacturer's recommendations.
            2.2.   If the power measurement can be carried out only on an engine with the gearbox mounted, the efficiency of the gearbox shall be taken into account.
            2.3.   Auxiliaries and equipment
            2.3.1.   Auxiliaries and equipment to be fitted
            During the test, the auxiliaries necessary for the engine operation in the intended application (as listed in Table 1) shall be installed on the test bench as far as possible in the same position as in the intended application.
            2.3.2.   Auxiliaries and equipment to be removed
            Certain auxiliaries whose definition is linked with the operation of the machine and which may be mounted on the engine shall be removed for the test. The following non-exhaustive list is given as a sample:
            
                        (a)
                     
                     
                        Air compressor for brakes
                     
                  
                        (b)
                     
                     
                        Power steering compressor
                     
                  
                        (c)
                     
                     
                        Suspension compressor
                     
                  
                        (d)
                     
                     
                        Air-conditioning system
                     
                  Where auxiliaries cannot be removed, the power they absorb in the unloaded condition may be determined and added to the measured engine power (see note h of Table 1). If this value is greater than 3 per cent of the maximum power at the test speed it may be verified by the test authority.

                  3.   Data to be recorded
            3.1.   Data to be recorded are those indicated in appendix A.1 to Annex 2. Performance data shall be obtained under stabilised 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 minimise the magnitude of the correction factor.
            3.2.   The temperature of the inlet air to the engine shall be measured within the inlet ductwork. The inlet depression measurement shall be made at the same point. The thermometer or thermocouple shall be shielded from fuel spray-back and radiant heat and located directly in the air stream. A sufficient number of locations shall be used to give a representative average of the inlet temperature.
            3.3.   The inlet depression shall be measured downstream of the entry ducts, air filter, inlet silencer or speed-limiting device (if fitted).
            3.4.   The absolute pressure at the entry to the engine downstream of the compressor and heat exchanger, if fitted, shall be measured in the inlet manifold and at any other point where pressure has to be measured to calculate correction factors.
            3.5.   The exhaust back pressure shall be measured at a point at least three pipe diameters downstream from the outlet flange(s) of the exhaust manifold(s) and downstream at the turbocharger(s), if fitted. The location shall be specified.
            3.6.   No data shall be taken until torque, speed and temperatures have been maintained substantially constant for at least one minute.
            3.7.   The engine speed during a run or reading shall not deviate from the selected speed by more than ± 1 per cent or ± 10 min, whichever is greater.
            3.8.   Observed brake load, fuel consumption and inlet air temperature data shall be taken simultaneously and shall be the average of two stabilised consecutive values which do not vary more than 2 per cent for the brake load.

                        in the case of naturally aspirated spark ignition engines.
                     
                  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 upper limit specified by the manufacturer for a clean air filter.
            
               (2)  The compete exhaust system shall be fitted as provided for the intended application:

               (8)  Charge air-cooled engines shall be tested with charge air cooling, whether liquid- or air-cooled, but if the manufacturer prefers, a test bench system may replace the air cooler. In either case, the measurement of power at each speed shall be made with the maximum pressure drop and the minimum temperature drop of the engine air across the charge air cooler on the test bench system as those specified by the manufacturer.
            
               (9)  The power for electrical or other starting systems shall be provided from the test bed.
            
               (1)  The tests may be carried out in air-conditioned test rooms where the atmospheric conditions may be controlled.
            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).

                  2.3.15.   Dual-fuel engines
            All engine types within a dual-fuel engine family shall belong to the same type of dual-fuel engines as defined in paragraph 2 of Annex 7 of 05 series of amendments to UN Regulation No 96, and operate with the same types of fuel or when appropriate with fuels declared according to this Regulation as being of the same range(s).
            3.   CHOICE OF THE PARENT ENGINE
            3.1.   General
            3.1.1.   Once the engine family has been agreed by the Type Approval Authority, the parent engine of the engine family shall be selected using the primary criterion of the highest fuel delivery per stroke per cylinder at the declared maximum torque speed. In the event that two or more engines share this primary criterion, the parent engine shall be selected using the secondary criterion of highest fuel delivery per stroke at rated speed.

               CHECKS ON CONFORMITY OF PRODUCTION
            
            1.   GENERAL
            These requirements are consistent with tests to be held to check Conformity of Production (CoP), according to paragraph 6.2 of this Regulation.
            2.   TEST PROCEDURES
            The methods of testing and measuring instruments shall be those described in Annex 4 to this Regulation.
            3.   COLLECTION OF SAMPLES
            3.1.   Case of an engine type
            One engine has to be chosen. If after the test of paragraph 4. below, the engine is not considered as conforming to the requirements of this Regulation, two more engines have to be tested.
            3.2.   Case of a family of engines
            In case of an approval granted to a family of engines the CoP shall be run on one member of the family, which is not the parent engine. In case of failure of the CoP test, the two more engines shall be of the same member type.
            4.   MEASUREMENT CRITERIA
            4.1.   Net power and specific fuel consumption of internal combustion engine
            Measurements shall be taken at a sufficient number of engine speeds to define correctly the power, torque and specific fuel consumption curves between the lowest and the highest engine speeds recommended by the manufacturer.
            The corrected values measured for the engine sampled shall not differ by more than the values indicated in the table below and ± 10 per cent for the specific fuel consumption.

                  3.2.2.3.   The engine test report for each test run shall include the following:
            
                        (a)
                     
                     
                        The admixture gas(es) chosen from the list in paragraph 3.2.2.1 of this Annex;
                     
                  
                        (b)
                     
                     
                        The value of Sλ for the resulting fuel blend;
                     
                  
                        (c)
                     
                     
                        The Methane Number (MN) of the resulting fuel blend.
                     
                  3.2.2.4.   The requirements of Appendices A.1 and A.2 shall be met in respect to determination of the properties of the pipeline and admixture gases, the determination of Sλ and MN for the resulting gas blend, and the verification that the blend was maintained during the test.
            
               (1)  The values quoted in the specifications are ‘true values’. In establishment of their limit values the terms of ISO 4259 ‘Petroleum products — Determination and application of precision data in relation to methods of test’ have been applied and in fixing a minimum 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 technical reasons, the manufacturer of fuels 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 questions as to whether a fuel meets the requirements of the specifications, the terms of ISO 4259 should be applied.
            
               (2)  The range for the cetane number is not in accordance with the requirements of a minimum range of 4R. However, in the case of a dispute between fuel supplier and fuel user, the terms of ISO 4259 may be used to resolve such disputes provided replicate measurements, of sufficient number to achieve the necessary precision, are made in preference to single determinations.
            
               (3)  Even though oxidation stability is controlled, it is likely that shelf life will be limited. Advice should be sought from the supplier as to storage conditions and life.
            
               (4)  Additives, such as cetane improver as specified by the engine manufacturer, may be added to the ethanol fuel, as long as no negative side effects are known. If these conditions are satisfied, the maximum allowed amount is 10 per cent m/m.
            
               (5)  The values quoted in the specifications are ‘true values’.

Notwithstanding this measure, which is necessary for technical reasons, the manufacturer of fuels shall 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 whether a fuel meets the requirements of the specifications, the terms of ISO 4259 shall be applied.
            
               (6)  Equivalent EN/ISO methods will be adopted when issued for properties listed above.
            
               (7)  Should it be necessary to clarify whether a fuel meets the requirements of the specifications, the terms of EN 15489 shall be applied.
            
               (8)  The values quoted in the specifications are ‘true values’. In establishment of their limit values the terms of ISO 4259 Petroleum products — Determination and application of precision data in relation to methods of test have been applied and in fixing a minimum 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).

Should it be necessary to clarify whether a fuel meets the requirements of the specifications, the terms of ISO 4259 shall be applied.
            
               (9)  Equivalent EN/ISO methods will be adopted when issued for properties listed above.
            
               (10)  A correction factor of 0,2 for MON and RON shall be subtracted for the calculation of the final result in accordance with EN 228:2008.
            
               (11)  The fuel may contain oxidation inhibitors and metal deactivators normally used to stabilise refinery gasoline streams, but detergent/dispersive additives and solvent oils shall not be added.
            
               (12)  Ethanol meeting the specification of EN 15376 is the only oxygenate that shall be intentionally added to the reference fuel.
            
               (13)  The actual sulphur content of the fuel used for the Type 1 test shall be reported.
            
               (14)  There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.
            
               (15)  The ethanol content and corresponding oxygen content may be zero for engines of category SMB at the choice of the manufacturer. In this case all testing of the engine family, or engine type where no family exists, shall be conducted using petrol with zero ethanol content.
            
               (16)  The values quoted in the specifications are ‘true values’. In establishment of their limit values the terms of ISO 4259 Petroleum products — Determination and application of precision data in relation to methods of test have been applied and in fixing a minimum 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).

Should it be necessary to clarify whether a fuel meets the requirements of the specifications, the terms of ISO 4259 shall be applied.
            
               (17)  The actual sulphur content of the fuel used for the emission tests shall be reported.
            
               (18)  Ethanol to meet specification of EN 15376 is the only oxygenate that shall be intentionally added to this reference fuel.
            
               (19)  The unleaded petrol content can be determined as 100 minus the sum of the per cent content of water, alcohols, MTBE and ETBE.
            
               (20)  There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.
            
               (21)  Balance shall be read as follows: balance = 100 – C3 – <C3 – >C4.
            
               (22)  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.
            
               (23)  At the request of the engine manufacturer, a higher MON could be used to perform the type approval tests.

            As an alternative to the above equation, Sλ may be calculated from the ratio of the stoichiometric air demand of pure methane to the stoichiometric air demand of the fuel blend supplied to the engine, as specified below.
            Lambda-shift factor (Sλ) expresses the oxygen demand of any fuel blend in relation to oxygen demand of pure methane. Oxygen demand means the amount of oxygen to oxidise methane in a stoichiometric composition of reaction partners to products of complete combustion (i.e. carbon-dioxide and water).
            For the combustion of pure methane the reaction is as set out in equation (A.7-4):
            
                        1 × CH
                           4 + 2 × O
                           2 → 1 × CO
                           2 + 2 × H
                           2

                  In this case the ratio of molecules in stoichiometric composition of reaction partners is exactly 2:
            
               
            Where:

                        =

                  The oxygen demand for pure methane is therefore:

            The value of Sλ may be determined from the ratio of the stoichiometric composition of oxygen and methane to the ratio of the stoichiometric composition of oxygen and the fuel blend supplied to the engine, as set out in equation (A.7-5):

                        the stoichiometric oxygen demand for the fuel
                     
                  Consequently the value of Sλ may also be determined from the ratio of the stoichiometric composition of air and methane to the ratio of the stoichiometric composition of air and the fuel blend supplied to the engine, i.e. the ratio of the stoichiometric air demand of methane to that of the fuel blend supplied to the engine, as set out in equation (A.7-7):
            
                        
                           
                     
                     
                        (A.7-7)
                     
                  Therefore, any calculation that specifies the stoichiometric air demand may be used to express the Lambda-shift factor.
