摘　　要：设计摩托车发动机顶置配气凸轮时,应先根据发动机配气机构的要求确定气门理论运动规律,然后再根据气门和凸轮的几何传动关系将确定的气门理论升程函数转化为对应的凸轮升程数据。设计计算表明,凸轮挺柱运动规律比气门理论运动规律前移或推迟了一定角度Δ_k值;试验表明,这种设计方法是可行的,新设计的配气凸轮改善了摩托车发动机的进气性能。When designing the overhead valve cam, the theoretical law of valve motion should be ascertained according to the demand of the engine valve train and then transform the determined valve theoretical lift function into the corresponding cam lift data according to the relation between the geometric transmission of the valve and cam. The design and calculation show that the law of the cam tappet motion moves forward or delays for a certain A k of angle comparing with the law of the theoretical valve motion. Tests show that this design is workable and the newly-designed valve train improves the air intake.
