In this case, the engine can only go to the repair shop to overhaul the engine. Reasons for cylinder flushing:
1, the main reason is the serious lack of lubricating oil, resulting in a sharp rise in friction temperature between the cylinder and the piston and between the connecting rod, at high temperatures;
2, due to the rapid change of the thermal expansion coefficient of the metal object, resulting in a sharp contraction of the lubrication gap, so that the piston and cylinder and connecting rod between the dead Angle, due to the strong effect of the inertia force, the cylinder block is severely damaged and scrapped;
3, if the mechanical lubrication gap between the piston and the inner wall of the cylinder is too large, it will also cause the mechanical impact of the piston on the cylinder block.
