在点燃式发动机中,三个不同的因素控制了整个燃烧过程:燃烧室的几何形状和火花塞的位置、可燃气体的等速运动和它的紊流特性以及汽油—空气可燃混合气的化学成分。本文研究这些因素的相互影响是为最佳燃烧室设计提供一个理论性的依据。其设计目的是以高的容积效率和最少传给缸壁热量来获得快速的、稳定的以及可重复燃烧且连续进行的循环。 In a spark ignition engine, three different factors control the entire combustion process: the geometry of the combustion chamber and the position of the spark plug; the constant velocity motion of the combustible gas and its turbulent characteristics; and the chemical composition of the gasoline-air combustible mixture. This paper investigates the interaction of these factors to provide a theoretical basis for the design of the best combustion chamber. It is designed to achieve fast, stable, repeatable and continuous circulation with high volumetric efficiency and minimal heat transfer to the cylinder wall.
