活塞环一旦失效,就会造成气缸内燃烧恶化,缸内平均温度升高,这样就使得与燃气接触机件的热应力增大。排气门、活塞也容易烧坏。活塞环的泄漏,破坏了气缸壁油膜,加速缸壁的磨损,严重时导致拉缸。如果泄漏的燃气与曲轴箱内的油雾一起燃烧,就会引起曲轴箱爆炸等事故。 Once the piston ring fails, it will result in deterioration of combustion in the cylinder, the average temperature inside the cylinder increases, thus making the thermal stress on the parts in contact with the gas increases. Exhaust valve, piston is also easy to burn. Piston ring leakage, destroyed the cylinder wall film, to accelerate the wear and tear of the cylinder wall, resulting in serious pull cylinder. If the leaking gas burns with the oil mist inside the crankcase, it can cause an accident such as a crankcase explosion.
