活塞与气缸的配合间隙一般用量缸表测量气缸内径尺寸和用外径分厘卡测量活塞裙部外径(其裙部位置:活塞裙部偏下并垂直于活塞销孔轴线方向)两者之差为其配合间隙。另外也可将活塞(不装活塞环)倒置于气缸中,以规定厚度的厚薄规片,在垂直于活塞销孔中心线的直线上,活塞裙部膨胀槽对面与活塞同时插入气缸内,用手推拉。对进口车同样用 Piston and cylinder with the general gap between the use of cylinder gauge measuring cylinder diameter size and the outer diameter of the PCT card measuring the outer diameter of the piston skirt (the skirt position: the piston skirt below and perpendicular to the piston pin axis direction) both Poor with the gap. In addition, the piston (without piston rings) can also be placed upside down in the cylinder, with a thickness gauge of the specified thickness, on the straight line perpendicular to the piston pin hole center line, Hand push and pull. The same for imported cars
