摘　　要：根据HS-990型发动机缸内工作过程的特点,建立了缸内工作过程准维模型,并恰当地确定了计算的边界条件。发动机缸内工作过程的计算结果与实测值能够较好地吻合证明了模拟计算的正确性。应用本模型可以预测结构参数变化对发动机性能的影响。According to the characteristics of HS-990 engine, a quasi-dimensional model for incylinder working process is developed and the computational boundary conditions are correctly determined. The calculated results from in-cylinder working process of the engine are found to be in coincidence with those of the actual measurement, whereby the correctness of simulation calculation is proved. Accordingly, the application of this model can predict the effect of variations in structure parameters upon the engine oerformances.
