1.拉缸的特征柴油机汽缸因受高温高压气体的推动、爆震或活塞剧烈的摩擦都会使缸壁拉伤,并在汽缸壁上沿活塞运行的方向出现一条条深度不等的竖向沟槽和金属剥落杂质,从而影响柴油机正常工作.此现象称为拉缸。这是在无外来物的情况下.由于活塞环外表面与汽缸表面滑动接触时.在极小的表面上产生很高的温度.进而引起活塞环
1. Characteristics of cylinder Cylinder cylinder due to high temperature and pressure due to the promotion of gas, detonation or piston fierce friction will make the cylinder wall strain, and in the cylinder wall along the direction of piston appears a vertical depth of the groove Slot and metal flaking impurities, thus affecting the normal operation of the diesel engine.This phenomenon is called pulling cylinder. This is in the absence of foreign objects due to the outer surface of the piston ring in sliding contact with the surface of the cylinder in a very small surface temperature is very high and then cause the piston ring
