摘　　要：汽油发动机富氧燃烧可改善发动机的燃烧效率和排放。文中对汽油发动机燃烧循环波动和NOx排放的机理进行研究,通过建立模型验证发动机试验数据。研究结果表明:建立的发动机燃烧循环波动和NOx排放模型与试验结果一致。富氧燃烧可以降低发动机燃烧的循环波动,同时降低发动机CO、HC排放物,但NOx的排放物有所增加。Oxygen-enriched combustion can improve efficiency of combustion and emission in gasoline engine. It is researched by theory of combustion cycle-to-cycle variation and NOx emission for oxygenenriched combustion engine to theorys and models, complete confirmation of engine test. The research results show that it is accordance of models conclusion and test for combustion cycle-to-cycle variation and NOx emission. Oxygen-enriched combustion reduces combustion cycle-to-cycle variation of engine and emission of CO, HC,but emission of NOx increases.
