【摘要】 本文对95柴油机配气系统进行了分析,指出由于系统刚度低,凸轮过渡段高度不够,使气门落座冲击较大,影响气门和座的工作可靠性和寿命。凸轮配气相位的选择不利于低速性能,发动机的使用经济性不好。文章提出了改进配气系统工作平稳性和发动机低速性能的方案。更多还原

【Abstract】 The valve gear mechanism of 95 series diesel engine has been analysed due to itslower stiffness and smaller cam ramp height,which cause valve bounce on seating,and its improper selection of valve timing which provokes poor fuel economy at enginelow speed.Improvement in working smoothness of valve gear system and better per-formance at engine low speed are also discussed.更多还原
