| 摘 要： | 对我国典型炼油工艺生产的组分汽油进行分析、调合，采用发动机台架试验，考察了汽油中芳烃含量及种类对Ford DHE420发动机常规和非常规污染物排放的影响情况。结果表明，汽油中芳烃含量增加，尾气中CO排放增加，碳氢化合物和NOx排放变化不明显，甲醛、甲醇和小分子烃类化合物排放减少，甲苯排放升高，1,3-丁二烯和苯排放几乎不变；烷基化汽油中加入7%的不同种类芳烃化合物不会显著影响发动机常规污染物排放，不同的芳烃在尾气中生成甲苯和苯的趋势各不相同。

| Abstract: | Gasoline blending and individual hydrocarbon analysis were done for gasoline fractions of domestic typical refining process. Effects of aromatics content and aromatics species in gasoline on regular and non-regular pollutants of exhaust emission gases were tested on Ford DHE420 engine. The results showed that increase of the aromatics content in gasoline led to higher CO and toluene emissions, as well as lower formaldehyde, methanol and small molecular hydrocarbon emissions. 1,3-butadiene，benzene and NOx emissions were not evidently correlated with the aromatics content of gasoline. Different aromatic species in gasoline got different generation trends of benzene and toluene. |
