连杆是发动机组成的重要传动零件之一，其作用是连接活塞与曲轴，并将活塞所受的气体爆发力传给曲轴，使活塞的往复运动变成曲轴的旋转运动。连杆在长期使用中，会因活塞的剧烈推力和曲轴的高速运转等因素，致使连杆出现弯曲和扭曲等现象。连杆一旦出现弯曲和扭曲，除产生活塞?
The connecting rod is one of the important transmission parts composed of the engine. Its function is to connect the piston with the crankshaft, and transmit the gas explosion force suffered by the piston to the crankshaft so that the reciprocating motion of the piston becomes the rotational movement of the crankshaft. Connecting rod in long-term use, due to the strong piston thrust and crankshaft high-speed operation and other factors, resulting in connecting rod bending and twisting phenomena. Once the connecting rod bending and distortion, in addition to produce piston?
