The Difference and Technology Strategy of Evaporative Emissions Test Phase Ⅱ and Ⅲ
Jiang Guohua （Hainan Automobile Test Research Institute）
Abstract:
Based on the test equipment,test preparation and test process,this paper compares the difference in evaporative emissions test method between 《GB 18352.2-2001 Limitation and Measuring Methods for Light-Duty Vehicle Emission （Ⅱ）》and 《GB 18352.3-2005 Limitation and Measuring Methods for Light-Duty Vehicle Emission （China Ⅲ, Ⅳ） 》 ; based on fuel supply and fuel evaporation control equipment,this paper also analyzes how to decrease evaporative emissions and presents technical methods to reach evaporative emissions standard Ⅲ;the relationship between maintenance,filling emission control and fuel evaporative emissions decrease for vehicle in use is also discussed in this paper[著者文摘]
