1.缸盖螺栓扭矩愈大愈好吗?在安装缸盖时,有的机手认为缸盖螺栓扭矩愈大密封性愈好,往往将扳手接长,以过大的扭矩紧固缸盖螺栓。其实这是不正确的,因为这样做会使缸体螺栓孔周围变形、凸出,造成接合面不平;缸盖螺栓也因经常受到过大的应力而被拉长或螺纹滑扣,使接合面的压紧力减小且不均匀。由此可见,缸盖 1 cylinder head bolt torque bigger? In the installation of cylinder head, some of the hands that the greater the cylinder head bolt torque, the better the sealing, often the wrench then long, tighten the cylinder head bolts with excessive torque . In fact, this is not correct, because doing so will make the cylinder bolt holes around the deformation, protruding, resulting in uneven joints; cylinder head bolts are often subject to excessive stress is elongated or threaded slippage, so that the joint surface The pressing force is reduced and uneven. Thus, cylinder head
