摘　　要：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 。This paper investigates the influence of angle between two cams on the gas exchange process by simulation.The engine is a single cylinder,four stroke,water cooled,direct injection diesel engine.It is found that the phases of maximum volumetric efficiency and lowest work loss in the gas exchange process are not the same,and we could not give consideration to both high speed and low speed with the same camshaft.
