乘用车用发动机的缸径与行程

Cylinder Bore Diameter and Stroke of Passenger Car Engine

发动机的缸径和行程是发动机的基本尺寸,是显著影响发动机性能和结构的重要主参数。基于全球乘用车发动机的相关数据,进行研究和分析,归纳和总结出发动机缸径和行程的经验值范围,为汽车主机厂和发动机制造商的产品规划和设计、开发提供参考。

The cylinder bore and stroke of the engine are the basic dimensions of the engine and the important main parameters which have significate influence on engine performance and structure.Based on the relevant data of passenger car engines around the world,this paper studies and analyzes the cylinder bore and stroke of series of engines and concludes the empirical range for these parameters,which provide reference for engine family planning,engine design and development for automotive OEMs and engine manufactures.
