摘    要:为研究轻型汽油车尾气中VOCs的排放特征和排放因子,按照《轻型汽车污染物排放限值及测量方法》(中国Ⅲ、Ⅳ阶段)中要求,采用底盘测功机对国内现有不同品牌轻型汽车进行台架试验,并利用3级冷阱预浓缩GC-MS方法对尾气样品中VOCs物种进行定量分析.结果表明,尾气样品中共有68种VOCs被定量检出,其中芳香烃种类最多,占38.7%,烷烃占29.8%,烯烃(包含炔烃)占27.1%.不同品牌轻型车源排放谱特征基本吻合.轻型汽车的总VOCs排放因子为0.01~0.46g/km,前3位物种分别为乙烯、甲苯和苯.

关 键 词:轻型汽油车  挥发性有机物(VOCs)  台架试验  排放因子  源成分谱

Abstract:In order to study the VOCs emission characteristics and emission factors of the exhaust gas of light-duty gasoline vehicles,different types of light-duty gasoline vehicles in used were tested with a chassis dynamometer according to Limits and Measurement Methods for Emission from Light-duty Vehicles(Ⅲ,Ⅳ).VOCs species in exhaust gas samples were analyzed by gas-chromatography and mass spectrometry coupled pre-concentration.68 VOCs in exhaust gas samples had been quantitative detected,aromatics,alkanes and alkenes(with acetylene) account for 38.7%,29.8% and 27.1% respectively.In addition,the source profile for different types of vehicles agreed well with each other.The total VOCs emission factor for light-duty gasoline vehicle is 0.01-0.41g/km.Ethane,toluene and benzene ranked the top 3 with the highest emission factors.
Keywords:light-duty gasoline vehicle  volatile organic compounds(VOCs)  dynamometer experiment  emission factor  source emission profile
