一、背负式弥雾喷粉发动机为什么采用二冲程汽油发动机? 答:首先要从二冲程汽油机的优缺点谈起,二冲程汽油机曲轴每转一圈就作一次功。和四冲程汽油机相比,当排量、压缩比、转速和每循环供油量等条件相同时,理论上功率应比四行程汽油机大一倍,运转平稳性也较好,飞轮尺寸可以减小,又省去了配气系统。因此,二冲 First, the piggy-back misting engine Why two-stroke gasoline engine? A: First of all from the advantages and disadvantages of two-stroke gasoline engine, two-stroke gasoline engine crankshaft made a revolution for each revolution. Compared with the four-stroke gasoline engine, when the displacement, compression ratio, speed and fuel consumption per cycle and other conditions are the same, the theoretical power should be double the four-stroke gasoline engine, running smoothly and flywheel size can be reduced , But also eliminates the gas distribution system. Therefore, two red
