1 Scope
This standard specifies the test and calculation methods for calculating fuel consumption by carbon balance method via measuring the emission of carbon dioxide (CO2), carbon monoxide (CO) and hydrocarbon (HC) of automobiles, as well as the inspection and judgment methods of production consistency.
This standard is applicable to such vehicles of Category N1 with the maximum design speed greater than or equal to 50km/h and those of Categories M1 and M2 with maximum mass less than 3,500kg as are powered by positive-ignition engines or compression-ignition engines. Reference may be made to this standard for vehicles of Category M1 with maximum mass exceeding 3,500kg.
This standard is applicable to vehicles that can burn gasoline or diesel oil, and is not applicable to hybrid electric vehicles; reference may be made to this standard for vehicles burn other fuels.
