This Standard specifies the requirements for type approval of the emissions from light-duty vehicles in the Stage V, check and verification methods of conformity of production and in-service conformity. This Standard is modified in relation to the technical content contained in the REGULATION (EC) No 715/2007 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on type approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, COMMISSION REGULATION (EC) No 692/2008 implementing and amending Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, and ECE R83-06 (2011) Uniform provisions concerning the approval of vehicles with regard to the emission of pollutants according to engine fuel requirements as well as their amendments. The following significant changes have been made in this Standard to the above EU directives: - The definition and category of light-duty vehicles follow the requirements in GB 18352.3-2005; - REVISE the previous Type II test and smoke test. - ADD the test requirements for effective volume and initial working capacity of canister; - ADD the test requirements for substrate volume and precious metal content of catalytic converter; - REVISE and adopt the related requirements for access to the OBD system and vehicle maintenance/repair information; - REVISE the method of verifying the conformity of production; ADD the requirements for checking conformity of production of carbon canister and catalytic converter; - ADD the requirements for checking evaporative emissions with regard to in-service conformity; - Exclude the test requirements for flexible fuel vehicles and biodiesel vehicles, etc.; - The technical requirements for test fuels. This Standard specifies the requirements for type-approval of the emissions from light-duty vehicles in the Stage V, check and verification methods of conformity of production and in-service conformity. Compared with the Stage IV, the significant changes are as follows: - The application scope of the standard extends to the vehicles with reference mass of not exceeding 2610 kg and specifies that the light-duty hybrid electric vehicles shall comply with the requirements of this Standard; - Improve the emission control requirements of Type I test; REVISE the measurement method of particulate matter mass and add the measurement requirements of particle numbers; - Categorize the two-speed idle test of positive ignition vehicles and free acceleration smoke test of compression ignition vehicles as the Type II test; - Improve the distance requirements for durability in Type V test; ADD the standard road cycle and bench ageing test method for positive ignition engines; - ADD the test requirements for effective volume and initial working capacity of canister; - ADD the test requirements for substrate volume and precious metal content of catalytic converter; - REVISE the requirements for monitoring items and limit values of the OBD system and the onboard diagnostic techniques of bi-fuel vehicles; - REVISE the related requirements for access to the OBD system and vehicle maintenance/repair information; - REVISE the method of verifying the conformity of production; ADD the requirements for checking conformity of production of carbon canister and catalytic converter; - REVISE the related requirements for in-service conformity check; ADD the requirements of checking OBD system and evaporative emissions; - ADD the technical requirements for vehicles that use a reagent for the exhaust after-treatment system; - ADD the procedure for emission test of vehicles equipped with periodically regenerating systems; - REVISE the technical requirements for test fuels. Annexes A, C, D, E, F, G, H, I, J, K, L, M, N, O, and P in this Standard are Normative Annexes, while Annex B is an Informative Annex. This Standard was organized and formulated by the Department of Science, Technology and Standards of Ministry of Environmental Protection. This Standard was drafted by Chinese Automotive Technology and Research Center and Chinese Research Academy of Environmental Sciences. This Standard was approved by the Ministry of Environmental Protection on May 27, 2013. From the issuance date of this Standard, this Standard can be deemed as the basis for type approval. From the date of January 1, 2018, all light-duty vehicles sold and registered shall comply with the requirements in the Standard. From the date of January 1, 2018, this Standard replaces Limits and measurement methods for emissions from light-duty vehicles (CHINA III, IV) (GB 18352.3-2005). Prior to January 1, 2023, the “In-service conformity check” for light-duty vehicles of Stage III and IV shall follow the relevant requirements stated in GB 18352.3-2005. This Standard is interpreted by the Ministry of Environmental Protection. Limits and measurement methods for emissions from light-duty vehicles (CHINA 5) 1 Scope of application This Standard specifies the limits and measurement methods for exhaust emissions at normal and low ambient temperature, exhaust emissions at two-speed idle condition, crankcase emissions, and evaporative emissions, and technical requirements and measurement methods for the durability of pollution control devices and onboard diagnostic (OBD) systems of light-duty vehicles equipped with positive-ignition engines. This Standard specifies the limits and measurement methods for exhaust emissions at normal ambient temperature and free acceleration smoke, and technical requirements and measurement methods for the durability of pollution control devices and OBD systems of light-duty vehicles equipped with compression-ignition engines. This Standard specifies the requirements for type-approval of light-duty vehicles, check and verification methods of conformity of production and in-service conformity. This Standard also specifies the special requirements for light-duty vehicles fueled by LPG or NG. This Standard also specifies the type-approval procedure for replacement pollution control devices as separate technical units intended to be fitted on light-duty vehicles with respect to pollutant emissions. This Standard also stipulates the technical requirements for vehicles that use a reagent for the exhaust after-treatment system and the procedure for emission test of vehicles equipped with periodically regenerating systems. This Standard applies to light-duty vehicles, including hybrid electric vehicles, powered by positive-ignition engines or compression-ignition engines, with the maximum design speed of being greater than or equal to 50 km/h. At the manufacturer's request, type approval may be performed for Category M1, M2, and N2 vehicles with the maximum mass exceeding 3500 kg and a reference mass not exceeding 2610 kg in accordance with this Standard; as for the vehicles type approval granted under this Standard may be extended from vehicles mentioned above to M1, M2, N1 and N2 vehicles .......
