Status Quo and Analysis of Evaporative Emission from Domestic Lignt-duty Gasoline Vehicle

本文简述了汽油车污染物的来源及控制汽车车蒸发排放的必要性,比较分析了常用的两种蒸发排放测量方法,基于大量测量结果说明了国产轻型车蒸发排放现状,试验分析了蒸发排放影响因素。

This paper briefly described the source of pollutants from gasoline-fuelled vehicles and the necessity of controlling the evaporative emission,and then compares the two common measuring methods for evaporative emission. Based on the test results the paper illustrates the status quo of evaporative emission from domestic light-duty gasoline vehicles. Through the test results,the factors affecting vehicle evaporative emission are analyzed.
