1 Scope
This standard specifies the limits and measurement methods for exhaust pollution, crankcase pollution and evaporation pollution in normal and low temperatures from light-duty vehicles with positive ignition engines. It states the durability requirements for pollution control equipment and the technical requirements and measurement methods for OBD system.
This standard specifies the limits and measurement methods for exhaust pollution in normal temperature, the durability requirements for pollution control equipment and the technical requirements and measurement methods for OBD systems for light-duty vehicles with compression ignition engines.
This standard stipulates the requirements for type approval, production conformity and vehicle-in-service conformity check and diagnosis for light-duty vehicles.
This standard specifies the special requirements for LPG or NG light-duty vehicles.
In addition, this standard states the type approval process for pollutant emissions from catalysts that, as stand alone technology, are to be installed on light-duty vehicles as an alternative.
This standard is applicable for light-duty vehicles that use positive ignition or compression ignition engines with the maximum designed speed greater than or equal to 50km/h.
This standard is not applicable for vehicles categorised as N1 that have received type approval according to GB 17691 (III or IV).
