| 摘 要： | 选用色谱－质谱联用中的选择离子检测技术研究了柴油机多环芳香烃放规律，分析了苯并药芘来源，并采用１３工况法测定了１４种曲环芳香烃物质的比排放量。结果表明，多环芳香烃排放量随着工况的改变有很大的变化；苯并芘完全是在燃料燃烧过程中的；有较多苯环的多环芳香地烃比排放量小，而具有较少苯环的多环芳香烃比排放量大。

| Abstract: | The study on emission regularities of polycyclic aromatic hydrocarbons from diesel engine have been conducted using the detecting technique of ion selection of gas chromatography and mass spectrum. Meanwhile, the source of benzo(a) pyrene in exhaust emissions has been analyzed. The brake specific emissions of 14 varieties of typical PAHs have been detected according to the 13 state cycle standard. The test result shows that the emission levels of PAHs varies greatly with engine's operation conditions. The emitted benzo(a) pyrene comes from the combustion process of the fuel. The brake specific emissions of PAHs with less benzene rings are higher than those with more benzene rings. |
