建立了一个利用进排气压力波来预测四冲程柴油机充气效率的模型,并用实测结果证实了模型的有效性。同时还依据计算结果分析了多缸柴油机各缸充量的不均匀性。
A model for predicting the charge efficiency of a four-stroke diesel engine by using pressure wave of intake and exhaust was established. The measured results validated the effectiveness of the model. Based on the calculation results, the inhomogeneity of each cylinder of multi-cylinder diesel engine is also analyzed.
