汽车发动机在解体检修过程中,要测量缸体各缸孔内径尺寸,凡磨损超过一级标准(0.25mm)的缸孔,就应按规定加级别配置相应新活塞(成组配置),并按制造厂规定的配缸间隙范围,对各缸孔进行镗、磨,使其达到规定的技术要求。影响正确配缸间隙的因素很多,为了提高发动机修理质量,现将操作要点分述 During the process of dismantling and repairing, the internal combustion engine cylinder bore size should be measured. Where the cylinder bore exceeds Grade I (0.25mm), the corresponding new piston (group configuration) should be configured according to the provisions and press the The provisions of the manufacturer with cylinder clearance range, the cylinder bore boring, grinding, so that it meets the required technical requirements. Affect the correct allocation of cylinder clearance many factors, in order to improve the quality of engine repair, now the operating points described
