Scope

This Standard stipulates the test and calculation method that uses the carbon balance
method to calculate fuel consumption, and the inspection and determination method
of production conformity through the determination of automobile carbon dioxide (CO2),
carbon monoxide (CO) and hydrocarbon (HC) emissions.
This Standard is applicable to Type-N1 vehicles, whose maximum design speed is
greater than, or equals to 50 km/h, and Type-M1 and Type-M2 vehicles whose
maximum design total mass does not exceed 3,500 kg, powered by ignition engine or
compression ignition engine; Type-M1 vehicles whose maximum design total mass
exceeds 3,500 kg may take this as a reference.
This Standard is applicable to vehicles that can burn gasoline or diesel, but not
applicable to hybrid electric vehicles. Vehicles of other fuel types may take this as a
reference.

Summary	This standard specifies the test, calculation method, and production consistency inspection and judgment method for calculating fuel consumption by carbon balance method by measuring carbon dioxide (CO?), carbon monoxide (CO) and hydrocarbon (HC) emissions from automobiles. This standard is applicable to N1 category vehicles powered by spark-ignition engine or compression-ignition engine with a maximum design speed greater than or equal to 50km/h and M1 and M2 category vehicles with a maximum design gross mass not exceeding 3500kg. M1 vehicles with a maximum design total mass of more than 3500kg may refer to the implementation. This standard applies to vehicles that can burn gasoline or diesel, but not to hybrid electric vehicles; other fuel types of vehicles can be implemented by reference.
