This document applies to M1 vehicles that can burn gasoline or diesel fuel and whose maximum design total mass does not exceed 3 500 kg. This document does not apply to vehicles that only use gas fuels or alcohol- ether fuels. 2 Normative references The contents of the following documents constitute the indispensable clauses of this document through normative references in the text. For dated references, only the version corresponding to that date is applicable to this document; for undated references, the latest version (including all amendments) is applicable to this document. GB/T 15089-2001, Classification of power-driven vehicles and trailers GB/T 19233, Measurement methods of fuel consumption for light-duty vehicles GB/T 19596, Terminology of electric vehicles GB/T 19753, Test methods for energy consumption of light-duty hybrid electric vehicles 3 Terms and definitions Terms and definitions determined by GB/T 19596 are applicable to this document. 4 Application for type certification 4.1 The application for type certification of a certain model or series of fuel consumption shall be submitted by the manufacturer or its legal representative. 4.2 The following documents and detailed information shall be attached to the application (if there is a schematic diagram, the details shall be fully explained in an appropriate proportion): a) Description of engine system characteristics that are specified in Appendix A; b) The fuel consumption type certification application report that is specified in Appendix B, where the content of B.8 shall not be filled. 4.3 A sample car that represents the certified model or series shall be submitted to the testing agency responsible for the type certification test. 5 Measurement of fuel consumption The fuel consumption of gasoline, diesel, bi-fuel and dual-fuel vehicles shall be measured in accordance with GB/T 19233, by using the Worldwide harmonized Light vehicles Test Cycle (WLTC). The fuel consumption of externally rechargeable and non-externally rechargeable hybrid electric vehicles shall be measured in accordance with GB/T 19753, by using the Worldwide harmonized Light vehicles Test Cycle (WLTC). 6 Determination and recording of type certification values 6.1 The testing agency responsible for the type certification test shall determine the fuel consumption type certification value (comprehensive fuel consumption) of gasoline, diesel, bi-fuel and dual-fuel vehicles in accordance with GB/T 19233, and determine the fuel consumption type certification value (comprehensive fuel consumption) of externally rechargeable and non- externally rechargeable hybrid electric vehicles in accordance with GB/T 19753. 6.2 Compare the comprehensive fuel consumption type certification values that are determined in 6.1 with the corresponding limits in Formula (1) ~ Formula (6); record the type certification values and the comparison results in the fuel consumption type certification report that is specified in Appendix B.
