摘　　要：本文运用概率统计的原理，用随机点法建立了一个适用于各种汽油机燃烧室的几何计算模型，可以方便而精确地计算球面火焰在燃烧室的传播过程。从圆筒形燃烧室中火焰传播过程的计算，证实了模型的有效性；运用该计算模型计算了ＣＡ６１０２汽油机燃烧室内火焰传播过程中火焰前锋面积、已燃区体积随火焰传播距离的变化关系。A simulation model has been set up for the combustion chamber of gasoline engine on the basis of random points,and the model proposed in this paper can provide accurate results of the spherical flame propagation by means of statistics.The calculating results of the flame propagation in the hole verify that the model is valid, and the flame front area and the volume of burnt zone versus the flame radius in the combustion chamber of CA6102 gasoline engine is got by using the model.
