二冲程摩托车发动机在结构上与四冲程发动机不同,所以它的活塞环相对于四冲程发动机更容易折断或卡在气口上,而造成发动机压缩无力或不能启动。 当怀疑二冲程发动机压缩无力、活塞环折断时,通常的检修方法是卸下缸盖、化油器、排气管,然后卸下 Two-stroke motorcycle engines are structurally different from four-stroke engines, so their piston rings are more likely to break or jam on the air ports than four-stroke engines, causing the compressor to become sluggish or unable to start. When it is suspected that the two-stroke engine is weak in compression and the piston ring is broken, the usual method is to remove the cylinder head, carburetor, exhaust pipe, and then remove
