增加充量运动能改善燃烧并扩大稀燃极限是现代汽油机改善经济性和控制排污的重要方法。近年来国外对它进行了大量的研究。本文较全面的论述了国外对充量运动研究的观点,发展过程及目前的水平。较系统地分析了各种充量运动形式:涡流、挤流及紊流。它们的形成机理、理论计算及试验研究的结果。 Increasing the amount of exercise to improve combustion and increase the lean burn limit is an important way for modern gasoline engines to improve their economy and control their emissions. In recent years, it has done a lot of research abroad. This article expounds the foreign viewpoints, development process and present level of research on the research of the full-scale movement more comprehensively. A more systematic analysis of a variety of forms of motion: swirl, squish flow and turbulence. Their formation mechanism, theoretical calculations and experimental research results.
