【摘要】 使用AVL发动机配气机构模拟分析用Tycon软件和发动机性能模拟分析用Boost软件,对一车用电控柴油机配气机构进行仿真评估和改进。研究表明,采用经优化的多项凸轮方案,可对原方案进排气凸轮的丰满系数得到改善,并较大幅度地降低进排气凸轮与从动件的接触应力水平,而使发动机仍保持原理想的性能指标。更多还原

【Abstract】 By using both AVL-Tycon (Valve trains system dynamics analyzing software) and AVL-Boost (Engine cycle simulation software), valve train system of an electronic-controlled vehicle diesel engine is analyzed and improved. The investigation shows that by adopting new polydyne cam profile, the new project will obtain higher fullness ratio and decrease contact stress between cam and follower obviously when the performance of original engine is kept good.更多还原
