| 摘 要： | 本文建立了内燃机换气过程缸内压力模拟计算的数学模型。其特点是缸内过程由开口系控制方程控制，进排气管内的过程由特征线法进行计算，进排气管与气缸之间由相应的边界方程相联系。通过实例计算，证明计算结果与实测值能较好地吻合。应用本文提出的方法，可以预测柴油机的换气损失等参数以及结构参数变化对换气过程的影响

| Abstract: | The article establishes a math model of cylinder pressure simulation of a diesel engine during gas exchange process.The cylinder process is controled by opening system equations,the intake and exhaust pipes are controled by character lines equations,and the boundaries between pipes and cylinder are linked by boundary equations.It is proved that the calculated results coincide with the measured ones by way of example.The gas exchange loss and the influence of gas exchange system structure on the parameters of gas exchange process can be forecasted by this model. |
