GB17691—2001
This standard is formulated to implement the "Environmental Protection Law of the People's Republic of China" and the "Law of the People's Republic of China on the Prevention and Control of Air Pollution" and to prevent and control the pollution of the environment caused by exhaust gases of automobiles equipped with compression ignition engines. This standard refers to the technical contents of Directive 91/542/EEC "Unified provisions on the measures taken by the Member States to control gaseous pollutants emitted by diesel engines for vehicles" which came into effect on October 1, 1991 and Regulation LCER49/02 of the United Nations Economic Commission for Europe "Uniform provisions on the certification of compression ignition engines and vehicles equipped with compression ignition engines with respect to engine pollutant emissions" which came into effect on December 31, 1992. This standard specifies the emission limits and traceability methods for type certification and production inspection tests at two implementation stages. The main contents of this standard are equivalent to the "Emission Standards for Exhaust Pollutants from Compression Ignition Engines for Vehicles" (GWPB62000), and the implementation shall still be carried out in accordance with the provisions of GWPB62000. ：
