利用柴油机换气过程缸内压力模拟计算软件，研究一台单缸柴油机配气凸轮夹角对换气过程的影响，该单缸机为四冲程水冷直喷式柴油机。结果表明，进排气门凸轮中心线夹角对充气效率、换气损失均有影响，但充气效率最佳点与换气损失最低点并不相同，且同一凸轮轴高低速性能不能兼顾。

This paper investi gates the influence of angle between two cams on the gas exchange process by sim ulation．The engine is a single cylinder， four stroke，water cooled，direct injectio n diesel engine．It is found that the pha ses of maximum volumetric efficiency and lowest work loss in the gas exchange pro cess are not the same，and we could not g ive consideration to both high speed and low speed with the same camshaft．
