前言汽缸套是柴油机心脏部分很重要的易损件之一。它的质量好坏直接影响着发动机的工作性能和寿命。汽缸套的工况非常恶劣,它不仅承受着反复作用的燃烧气休的最高压力、活塞侧压力及高温热应力,同时其内表面还遭受着燃烧产物的腐蚀及外表而遭受着冷却水引起的空泡腐蚀。因此,汽缸套应该具有足够的强度、组织致密性及一定的耐热、耐磨和抗蚀性等。 Introduction Cylinder liner is one of the most important wearing parts of the heart of a diesel engine. Its quality directly affects the performance and life of the engine. Cylinder liner is very bad condition, it not only withstand repeated play the highest pressure of combustion gas off, the pressure on the piston side and high temperature thermal stress, while its inner surface is also subject to combustion products corrosion and appearance suffered from cooling water Cavitation corrosion. Therefore, the cylinder liner should have sufficient strength, tightness and a certain degree of heat-resistant, wear-resistant and corrosion resistance.
