许多小型农用车多采用二冲程工作循环机型。二冲程发动机使用的燃油是由汽油和机油混合的,比例一般为15:1～20:1。采用混合油做燃料,同时起到润滑运动件的作用,从而就省去了四冲程的润滑系统。配制使用混合油似乎很简单,往往不被重视,然而时常走进误区。误区一:乱用普通机油使用混合用机油要用汽油机机油或LER—A二冲程机油。千万不要用普通机油或存放过久的汽油和机油,以确保机件正常润滑。误区二:混乱容积比和重量比区别不同车型都有不同比重比例要求。容积比
Many small agricultural vehicles to use more two-cycle working cycle models. The fuel used in two-stroke engines is mixed with gasoline and engine oil at a ratio of 15: 1 to 20: 1. The use of mixed oil as a fuel, while playing the role of lubrication of moving parts, eliminating the need for a four-stroke lubrication system. The use of blended oils appears to be simple and often overlooked, yet often goes the wrong way. Misunderstanding one: indiscriminate use of ordinary oil Mixing oil to use gasoline engine oil or LER-A two-stroke oil. Do not use ordinary oil or stored too long gasoline and oil to ensure the normal lubrication of the parts. Misunderstanding 2: confusion volume ratio and weight ratio Different models have different proportion of the proportion of requirements. Volume ratio
