发动机通过长时间运转之后,往往会产生连杆变形、曲轴变形、主轴颈和连杆轴颈中心线偏移、气缸中心线与曲轴中心线垂直度误差等,进而造成活塞偏缸。所谓活塞偏缸,就是曲轴连杆机构装配后,活塞任一位置时的轴线放后倾斜;或者说发动机在运转中,活塞在气缸内作偏于一侧的不正常运动。活塞偏缸是发动机装配与使用过程中经常出现的问题,它影响
After the engine runs for a long time, it will often produce the deformation of the connecting rod, the deformation of the crankshaft, the deviation of the centerline of the main journal and the connecting rod journal center, the perpendicularity error between the centerline of the cylinder and the center line of the crankshaft and the like, thereby causing the piston to bias the cylinder. The so-called piston cylinder, that is, crankshaft connecting rod assembly, the piston at any position when the axis put back tilt; or engine is running, the piston in the cylinder side to side of the abnormal movement. Piston bias cylinder is the engine assembly and use of the problems often occur, it affects
