This standard specifies the requirements for the CHINA 6 type inspection requirements, the consistency of production, and the inspection and determination methods for conformity of emissions from light-duty vehicles. Manufacturers are obliged to ensure that the vehicles they produce and sell meet the requirements for in-use conformance of this standard. Compared with GB 18352.5-2013 “Limits and measurement methods for emissions from light-duty vehicles (CHINA 5)”, the main changes in this standard include. - CHANGE the type I test cycle, TIGHTEN the pollutant emission limits, ADD the measurement requirements for the number of particulate emissions from gasoline vehicles; - DESIGNATE the real driving emission (RDE) test as type II test; - TIGHTEN the Type VI test items and limits; - REVISE technical requirements for monitoring items, thresholds and monitoring conditions for on-board diagnostic systems; - REVISE the relevant requirements for obtaining vehicle on-board diagnostic systems and vehicle maintenance and repair information; - REVISE the determination method of production consistency inspection and the relevant requirements for the in-use conformance inspection; - REVISE the technical requirements for test fuels; - ADD requirements for control of pollutants in the refueling process; - ADD test requirements for hybrid electric vehicles. This part of the standard modifies and uses European Union (EC) No 715/2007 “Regulations on Type Approval of Pollutants Emitted by Light Passenger Vehicles and Commercial Vehicles and Regulations on Obtaining Maintenance and Repair Information for Vehicles”, (EC) No 692/2008 “Regulations on (EC) the Implementation and Revision of (EC) No 715/2007 Regulations on Type Approval of Pollutants Emitted by Light Passenger Vehicles and Commercial Limits and measurement methods for emissions from light-duty vehicles (CHINA 6) 1 Scope This standard specifies the emission limits and measurement methods for exhaust emissions at normal temperature and low temperature, real driving emission (RDE) exhaust emissions, crankcase pollutants, evaporative emissions, and refueling pollutants, as well as the technical requirements and measurement methods for the pollutant control device durability and on-board diagnostics (OBD) systems of light-duty vehicles which are equipped with ignition type engine. This standard specifies the emission limits and measurement methods for exhaust emissions at normal temperature and low temperature, real driving emission (RDE) exhaust emissions, crankcase pollutants, as well as the technical requirements and measurement methods for the pollutant control device durability and on-board diagnostics (OBD) systems of light-duty vehicles which are equipped with compression-ignition type engine. This standard specifies the requirements and confirmation of light-duty vehicle type inspection, production conformance and in-use conformity inspection and determination methods. This standard also specifies special requirements for the light-duty vehicles which use liquefied petroleum gas (LPG) or natural gas (NG). This standard also specifies the type inspection procedures for pollutant emissions of the alternative pollutant control devices which are used as an independent technology assembly and proposed to be installed on light-duty vehicles. This standard also specifies the technical requirements for vehicles that use reactants in exhaust aftertreatment systems, as well as the emission test procedures for vehicles that are equipped with periodic regenerative systems. This standard applies to light-duty vehicles (including hybrid electric vehicles) powered by ignition engines or compression-ignition engines with a maximum design speed of 50 km/h or more. Under the requirements of production companies, category M1, M2, N1 and N2 vehicles with a maximum design total mass of more than 3500 kg can be subject to type inspection in accordance with this standard. This standard does not apply to vehicles that have passed the CHINA 6 type inspection in accordance with the provisions of GB 17691. The use of vehicles whose fuel types are not contained in Appendix K may be implemented with reference to the relevant provisions of this standard. 2 Normative references The following documents or clauses therein are referenced in this standard.
