摘　　要：发动机是汽车极为重要的一种部件,能够将热能转变为机械能以此来推动汽车运作。而发动机中,活塞是极为重要的部分,活塞的裙摆和末端在高温下会形成膨胀,从椭圆形变成圆形。因为间隙太小,配缸容易形成拉缸的情况,如果汽车在高速行驶的过程中出现拉缸事故,后果难以想象。有关汽车设计师应该对引起活塞拉缸的具体原因进行仔细分析,规避拉缸现象的发生。文章针对汽车发动机拉缸的主要原因进行了具体分析,并提出有效的预防措施。The engine is an extremely important part of the car,which can convert thermal energy into mechanical energy to promote the operation of the car.In the engine,the piston is an extremely important part.The skirt and end of the piston will expand under high temperature,changing from an ellipse to a circle.Because the gap is too small,the cylinder is likely to form a cylinder pulling situation.If the car has a cylinder pulling accident during high-speed driving,the consequences are unimaginable.Relevant automotive designers should carefully analyze the specific causes of piston cylinder pulling to avoid the phenomenon of cylinder pulling.The article makes a specific analysis of the main reasons for pulling cylinders of automobile engines,and puts forward effective preventive measures.
