摘要
凸轮发动机的机械效率是影响其动力性指标和经济性指标的一项重要参数。为了对新型凸轮发动机的机械效率进行分析,在分析新型凸轮发动机活塞受力的基础上,研究了新型凸轮发动机各运动副之间的摩擦损失,对新型凸轮发动机机械效率进行了估算。本文的方法可为活塞凸轮发动机的机械效率的计算提供参考。
Mechanical efficiency of cam engine is important for its power performan performance. In order to analyze the mechanical efficiency of a new type cam engine, the each kinematic pair are researched based on analyzing the force on piston of a new type cam mechanical efficiency of a new type cam engine is computed. The models in paper can computing cam engine ce and economy friction losses of engine, and be referred
