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.
