润滑是发动机的一个重要组成部分,发动机通过机油润滑,可以减少摩擦阻力,降低功率消耗,减轻机件磨损,延长使用寿命,同时起到密封和防锈作用。 二冲程发动机的润滑大体可分为混合式润滑和分离式润滑两种形式。混合式润滑是将汽油和机油以一定的比例混合在一起,然后汽油和机油泵进入化油器雾化进行润滑。这样易造成怠速时润滑油过浓,使润滑 Lubrication is an important part of the engine. Lubrication of the engine through the oil can reduce the frictional resistance, reduce power consumption, reduce mechanical wear and prolong the service life, at the same time, it can play the role of sealing and rust prevention. Two-stroke engine lubrication can be roughly divided into two types of hybrid lubrication and separate lubrication. Hybrid lubrication is a mixture of gasoline and oil in a certain proportion, and then gasoline and oil pump into the carburetor atomization for lubrication. This easily lead to excessive oil at idle speed, so lubrication
