如果在发动机使用的第一阶段,即发动机平均使用期的前一半,偶然故障是发动机送修的主要原因的话,那么在发动机使用的第二阶段,即从发动机平均使用期的后一半开始到行驶里程结束,其送修的主要原因多半是缸套—活塞组的磨损。为此,根据影响缸套几何形状变化的因素对-130发动机缸套的工作能力和耐磨性进行了研究。取缸套支承凸缘凸出于缸体平面的凸出量x_1、缸体、缸套上配合带之间的间隙x_2,缸体、缸套下配合带之
If during the first phase of engine use, the first half of the average engine life, the accidental breakdown is the main reason for engine repair, then during the second phase of engine use, from the second half of the average engine life until driving The end of the mileage, the main reason for the repair is mostly cylinder liner - piston group wear and tear. For this reason, the working ability and wear resistance of the -130 engine cylinder liner were studied based on the factors affecting the change of cylinder liner geometry. Take the cylinder liner flange protruding from the cylinder protruding amount x_1, the cylinder, cylinder liner with the gap between the belt x_2, cylinder,
