1 Application Scope
This standard specifies the measurement methods and technical requirements for exhaust pollutants, two-idle-speed exhaust pollutants, crankcase pollutants, evaporative pollutants, pollutant control device durability and on-board diagnostic system (OBD) of light-duty hybrid electric vehicle (HEV) equipped with spark-ignition engine under normal and low temperatures.
This standard specifies the measurement methods and technical requirements for exhaust pollutants, free acceleration exhaust smoke, pollutant control device durability and on-board diagnostic system (OBD) of light-duty hybrid electric vehicle equipped with compression-ignition engine under normal temperature.
This standard specifies the inspection and judgment methods for type test, production conformity and in-service conformity of light-duty hybrid electric vehicle.
This standard is applicable to light-duty hybrid electric vehicle equipped with spark-ignition engine or compression-ignition engine and with maximum design speed larger than or equal to 50km/h. For the vehicle with function of shutdown during parking and idle speed mentioned in QC/T 837, the emission shall be measured according to the requirements for conventional vehicle and shall not belong to the application scope of this standard.
