一、前言 二冲程发动机从诞生至今已有一百多年的历史了。这种发动机每转一周就作功一次,因此,在工作容积和转速相同的情况下,理论功率为四冲程发动机的两倍。此外因二冲程发动机没有专门的配气机构,故其结构简单、重量轻、便于维修。再者,二冲程发动机作功间隔短、频率大、运转较平稳。二冲程发动机所具有的重量轻、功率大、结构简单 First, the preface Two-stroke engine has been born from the birth of a hundred years of history. The engine relies on a single revolution per revolution, so twice the theoretical power of a four-stroke engine at the same working volume and speed. In addition, because the two-stroke engine does not have a special gas distribution mechanism, its structure is simple, light weight and easy to maintain. Second, the two-stroke engine work interval short, high frequency, more stable operation. Two-stroke engine with the light weight, high power, simple structure
