摘　　要：本文根据Benson等人提出的汽油机燃烧模型 ,考虑了燃烧室挤气面积对火焰传播速度的影响 ,对汽油机工作过程进行了数值模拟 ,并结合EQ610 0发动机实测数据找出了紊流火焰传播速度因子与发动机转速的关系。实验表明模拟结果是合理的 ,建立的汽油机燃烧过程模拟是可行的。Basing on the combustion model for SI engine suggested by R.S. Benson and considering the effect of squish area on the flame propagation process in SI Engines, we suggest a formula of flame propagation speed which is the function of the engine speed of the EQ6100 SI engine. All results computed are compared with the experimental results and the conclusion in some respects concerned as well. The results show that numerical simulation is reasonable and feasible.
