Progress of emission control standards for light-duty vehicles in China
Elevating standards for vehicle emissions is an effective approach to control vehicular emissions and improve air quality.Light-duty vehicles are the major contributors of HC and CO emissions for its large proportion in vehicle population,and controlling the light-duty vehicular emissions has always been the emphasis of air pollution prevention in China.The progress of the emission control standards in Chinese Mainland,Japan and developed countries in Europe and America were firstly introduced.And the features of China 6 emission standards were analyzed,namely continuation of European standards,import of World LightDuty Test Cycle,reference of American standards.Then the control method of light-duty vehicular emissions was proposed based on the analysis of the emission control technology,improvement of automotive fuels and the supervision of on-board diagnostics (OBD).The future development of emissions standards and emission control technologies were prospected.
