Based on the quasi-dimension combustion model, the emission model is set up in this dissertation. The NO emissions in different conditions of LPG engine can be simulated and calculated by the model. The calculated results show that the NO emissions are larger influenced by ignition timing and less influenced by compression ratio, finally, choosing a right coefficient of excess air will have great effect to reduce NO emissions.

本文在建立的准维燃烧模型基础上建立了排放生成模型，利用该模型对液化石油气发动机在变参数情况下NO的排放生成情况进行了模拟计算，计算结果表明点火提前角对NO的生成影响较大，压缩比对NO的生成影响较小，而选择合适的过量空气系数更是对降低NO的生成起着关键作用。
