近年来,有些教师和中学生常向笔者提出这样的问题:什么是二冲程摩托车?二冲程发动机的工作原理怎样?摩托车的发动机按原理可分为四冲程和二冲程两类,且后者的社会拥有量最多。中学课本中仅简单介绍了四冲程发动机的工作原理,在大学物理课程中一般也只是比较详细地分析了四冲程发动机的工作循环,而对二冲程发动机的工作原理则很少涉及。本文简单介绍一下二冲程发动机的工作原理,供读者参考。
In recent years, some teachers and high school students often ask the author this question: What is a two-stroke motorcycle? Two-stroke engine how the working principle? Motorcycle engine according to the principle can be divided into four-stroke and two-stroke two types, and the latter The largest number of social possessions. High school textbooks only briefly describes the working principle of a four-stroke engine. In the physics course of the university, it generally only analyzes the working cycle of a four-stroke engine in more detail. However, it rarely involves the working principle of a two-stroke engine. This article briefly describes the working principle of two-stroke engine, for readers reference.
