摘　　要：建立了一种用于计算火焰与各种几何形状的点燃式发动机燃烧室之间相互关系的计算模型，应用在发动机准维模型中能很好地满足火焰形状椭球化、火焰中心飘移等计算要求。能计算火焰前锋面积，已、未燃区体积和已、未燃区与燃烧室之间的传热面积等参数。通过有效性讨论，认为模型具有较好的精确性和适应性。A model was developed for the geometric interaction between flame and various combustion chamber geometry in SI engines, It can be used in quasi-dimensional engine simulation taking account of ellipsoid-shaped flame and flame center motion in the cylinder, and obtain flame front area, burned and unburned region volumes and heat transfer areaa between the combustion chamber and two regions. Finally, authers pointed out that this model is relatively accurate and adoptable.
