二冲程摩托车,不论采用的是混合润滑(如幸福250)方式还是分离式润滑(如重庆CY—80)方式,都有机油燃烧不完全的痼疾,且机油消耗量极大。 现在已经淘汰了老式混合润滑方式,大多数二冲程的车型都采用分离润滑,虽然从设计上分离润滑有减少机油消耗的企图,但效果并不理想。原因是,低速时油泵 Two-stroke motorcycles, whether using a mixture of lubrication (such as happiness 250) way or separate lubrication (such as Chongqing CY-80) approach, there is incomplete combustion of motor oil disease, and great oil consumption. Old-fashioned hybrid lubrication has now been phased out, with most two-stroke models adopting separate lubrication. Although the separation of lubrication from the design attempts to reduce oil consumption, the effect is not satisfactory. The reason is that low speed oil pumps
