二冲程汽油机扫气过程模拟试验方法的评价

Simulation Test Evaluation for Two Stroke Gasoline Engine Scavenging Process

在讨论摩托车二冲程汽油机扫气过程评价指标和影响扫气的几何参数的基础上,总结了二冲程汽油机扫气过程的模拟试验方法。通过比较和分析,提出扫气图法中的静态扫气试验是一种较好的试验和评价方法,其他模拟试验方法也都各有所长,对于静态扫气试验是很好的补充。

This paper provides a summary of different experimental methods of two stroke spark-ignition engine scavenging process. The evaluating norms are discussed and the geometric parameters, which are critical in the scavenging process of two stroke spark-ignition engine used in motorcycles, are analyzed. From the results, we can conclude that all the methods have their own strong points. But considering all the factors, the static scavenging experiment is more suitable and therefore more widely used than the others.
