| 摘 要： | 利用现场采样并将分析结果归一化处理后确立了以汽油、柴油、液化石油气(LPG)为燃料的汽车尾气以及汽油蒸气和液体汽油的VOCs源成分谱。研究显示汽油车和柴油车尾气的排放特征相近，而LPG车尾气以4个碳以下的烷烃、烯烃为主。汽油蒸气中，C5以下的化合物占较大比例，而液体汽油中则是以大于C6的化合物为主。

| Abstract: | The volatile organic compounds source profiles of motor vehicle exhaus t, gasoline vapor and liquid gasoline were determined by averaging the ratios of individual VOC species concentration to the total concentrion of all VOC specie s measured. The gasoline exhaust and diesel exhaust display similar distributions . The alkanes and alkenes below C4 are the most abundant compounds in liquefied petroleum gas exhaust. The compounds below C5 and above C6 are the majo r content in gasoline vapor and liquid gasoline respectively. |
