摘　　要：详细地介绍了汽油机加速工况时准维燃烧模型的建立过程。分析了加速工况和稳态工况下模型的区别,提出了加速工况时对稳态工况下模型的空燃比AF、充气效率、传热系数进行修正的方法。In this paper, a combustion model of gasoline engines under accelerating condition was introduced. The difference between stability model and accelerating model was analysis. Compared with stability condition, some revise methods concerning Air/Fuel ratio, volumetric efficiency and heat transfer coefficient under accelerating condition were put forward.
