Compliance overview
Scope and applicability
This standard applies to motorcycles and mopeds powered by spark-ignition engines, as well as positive three-wheeled motorcycles powered by compression-ignition engines. It is not applicable to vehicles exclusively fueled by gaseous fuels or alcohols. This standard replaces GB 15744-2008 and GB 16486-2008.
Technical requirements
The standard specifies the mandatory fuel consumption limits for various categories of motorcycles and mopeds. Limits are determined based on engine displacement, vehicle type (two-wheeled, sidecar, or three-wheeled), and transmission type (manual or automatic). Manufacturers must ensure their vehicle models meet the specified limits to achieve type approval in China. The standard also details the calculation methods for fuel consumption, combining results from different test phases using specific weighting factors.
Testing methods
Fuel consumption is evaluated through Type I tests (operating cycle on a chassis dynamometer) and Type II tests (constant speed at reference speed on a road or dynamometer). The standard permits several measurement methods, including flow measurement, volumetric measurement, gravimetric measurement, and the carbon balance method. Specific environmental conditions and vehicle preparation procedures must be strictly followed during testing.
