摘　　要：针对发动机配气机构设计与分析所提出的工程实践问题,导出了一整套出气门运动规律反求的计算理论,提出了发动机配气机构的配气定时分析的方法,分别对汽车、摩托车发动机配气定时的排气提前角、排气迟闭角、进气提前角、进气迟闭角及相应位置的气门位移和气门重叠角等进行了研究,揭示了中低速和高速发动机配气定时应有的参数特征。According to the engineering practice proposed by the design and analysis of engine valve train, the paper derives the complete computing theory of reversing the valve＇s motion law, put forward the analysis method of the valve timing of the engine valve train, researches the intake and exhaust valves＇ timing and their valve positions and overlap angles in the corre-sponding positions of the autocar and motorcycle＇s valve timing separately and disclosured the parameter features of the middle, low and high speed engine valve timing.
