摘　　要：为了深入研究内燃机工作过程,在直喷式柴油机准维多区燃烧模型中,考虑了油滴间的相互碰撞和聚合作用,及缸内燃烧和空气运动对燃油蒸发的影响及油滴蒸发的相互影响.通过计算结果与实验结果的对比,表明考虑了油滴相互作用的燃烧模型可以更准确地预测发动机性能.For study on the diesel working procedure, the collision and aggregation of droplets had been considered in the quasdimensional combustion model, and also the influence of burning and airmovement to fuel evaporation. Through the comparison of the calculated results with the experiment ones, we found that the model which consider interaction of fuel droplets can be used to predict the diesel performance more accurately.
