摘要
从试验设备、试验准备和试验过程3方面,比较了《GB 18352.2-2001轻型汽车污染物排放限值及测量方法(II)》与《GB18352.3-2005轻型汽车污染物排放限值及测量方法(中国IIII、V阶段)》两个标准在汽车蒸发污染物排放试验方法方面的差异;从燃油供给、燃油蒸发控制装置等方面,对降低车辆蒸发污染物排放进行了技术分析,提出了达到第III阶段蒸发污染物排放标准的技术措施;论述了在用车的维护保养和加油排放控制与降低燃油蒸发物的关系。
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
