This paper presents a study on characteristics of fueldistribution，diffuse and evaporation as well as face effect on characteristics by mathematical models. Thereby, the basis of precise control of air excess coefficient-λ of mixture in cylinders is provided in unsteady condition.%通过数学模型，对多点电喷汽油机喷油过程中燃油的分布、燃油雾化和蒸发特性及其影响因素进行了研究，从而为电喷汽油机在动态工况下缸内混合气的过量空气系数(at)的精确控制提供了设计依据。
