对摩托车发动机设计结构参数s/D的探讨

收集整理了日本近年来生产的200余款摩托车用发动机的基本结构参数,采用统计分析技术,对发动机最重要的设计参数s/D进行了探讨,从中了解到当代最先进的摩托车生产国日本的摩托车发动机在这一参数上的设计取值状况;并对典型排量(50、125、250、400、750、1000 mL等)的摩托车发动机的相应参数进行了针对性的统计分析,给出了一般取值范围及集中分布状况;在此基础上进一步分析了影响这些参数的有关因素。

A Study on the Design Structure Parameter s/D of Motorcycle Engine

A study of s/D is done with the help of the statistical analysis technique on the basis of the basic structure parameters collected from more than 200 types of Japanese-made motorcycle engines ,from which the value selection situation for the parameters in Japan can be seized up;in addition a statistical analysis of the relevent parameters of motorcycle engines (including those with displacement of 50,125,250,400,750,1 000 mL)is done with the general value selection range and concentrative distribution given.Also the relative factors influcing those parameters are studied in deep.
