摘　　要：分析微转子发动机的微小燃烧室内燃烧特点后,讨论了发动机燃烧室微燃烧中熄火距离的影响因素。并在三区准维模型的基础上,对比计算了不同熄火距离的燃烧特性。根据壁面熄火效应随熄火距离增大而增大,提出了减小熄火效应的措施。After analyzing the combustion characteristic of the Mini Wankel-Type Engine, this article discusses the influencing factor of the quenching effects to micro combustion. Based on Three-Zone Quasi Dimension model, we calculated the micro combustion characteristic of the slot chamber with several different quenching distances. The results show that the effects of wall quenching effects and the restrain to micro combustion mount up with the aggrandizement of quenching distance.
