所谓发动机“烧机油”，就是发动机的润滑油经有关机件配合缝隙窜入燃烧室内烧蚀的异常现象。如活塞和气缸壁之间的间隙，因磨损超限，当活塞下行时，进入活塞环与环槽之间的机油就增多，泵油作用加强，因而机油消耗增加，还会使环与环槽卡死．失去弹性，破坏密封性，使机油消 The so-called engine “burn oil”, is the engine lubricating oil through the relevant parts with the slit fleeing into the combustion chamber ablation anomaly. Such as the gap between the piston and the cylinder wall, due to wear and tear overrun, when the piston down, into the piston ring and ring groove between the oil increases, the role of pumping oil to enhance, thus increasing oil consumption, but also ring and groove Stuck. Lost elasticity, destruction of sealing, so that oil consumption
