发动机长期在高温下工作或骤冷，不按规定扭矩拧紧缸盖螺栓或用力不均等，均可引起发动机气缸体变形而使其上平面产生翘曲变形。此种现象在多缸发动机上表现突出，单缸发动机表现不明显。现就发动机气缸体上平面产生翘曲变形的主要原因，检查方法及修复方法介绍如下。１翘... Long-term engine work or quenching at high temperatures, not according to the provisions of the tightening of cylinder head bolts or torque is not equal, can cause deformation of the engine cylinder so that the upper plane has warping deformation. This phenomenon outstanding performance in the multi-cylinder engine, single cylinder engine performance is not obvious. Now on the plane of the engine cylinder block warping deformation of the main reasons for the inspection methods and repair methods are described below. 1 Alice ...
