利用端置式扫气泵来平衡二冲程发动机的离心力偶,并不是一个新颖的问题,在苏联及瑞士 Sulzer 等厂所制的一些发动机中很早已经使用.不过,这种平衡法的一般解法如何,在文献中尚少论及.笔者在带领同学实习时,曾经碰到过这个问题,后来经过思索及分析,得到了一些概念,本文所要谈的,就是这种平衡法的一般解法. The use of an end-mounted scavenging pump to balance the centrifugal couple of a two-stroke engine is not a novel problem that has long been used in some engines made by the Soviet Union and the Swiss factory Sulzer, etc. However, the general solution to this balancing approach, In the literature is still little talk about the author in leading the students practice, had encountered this problem, and later after thinking and analysis, got some concepts, this article is about, is the general solution to this balance of law.
