柴油机拉缸,是指气缸壁上沿活塞运行的方向出现一条条深度不等的沟纹。这是在无外来物的情况下,由于活塞环外表面与气缸表面滑动接触时,在极小的表面上产生很高的温度,进而引起活塞环与气缸壁之间烧熔、黏着,当烧熔、黏着所产生的热量散失后,在活塞环上产生碳化物。这种碳化物或烧熔、黏着生成物就像一把锋利的刀具,将气缸壁上的金属切去,从而形成一道道深浅不规则的沟槽。 Diesel tank, refers to the cylinder wall along the piston running direction of a strip of indentation depth. This is the case in the absence of foreign objects, as the outer surface of the piston ring in sliding contact with the surface of the cylinder, resulting in a very small surface temperature, and then cause the piston ring and the cylinder wall between the melting, adhesion, when the burning After melting, the heat generated by the adhesion is lost, carbide is generated on the piston ring. This carbide or sinter, sticky product is like a sharp knife, cut off the metal on the cylinder wall, thus forming a channel with irregular depths.
