摘　　要：相对汽油发动机污染物排放,柴油发动机CO和CH的排放较低,不到汽油机的10%,但NOX排放水平却高于汽油发动机。本文重点讨论柴油发动机排气污染物中NOx的成分及危害,分析了NO的生成机理及影响因素,提出了控制柴油机NO排放的技术和方法。Compared with gasoline engine emission,Diesel engine has low CO and CH emissions which is less than 10%. But NOX emission is much more than gasoline engines. This article focuses on the composi-tion and harm of NOX in diesel engine emission pollutants,has the analyse of the NO formation mechanism and influence factors,and propose the technology and methods to control NO emissions of diesel engine.

关 键 词：柴油机 排放 氮氧化物 控制
