气缸套的内表面状况是决定发动机大修间隔里程长短的关键因素,因此自本世纪初,各国开始重视研究与缸套磨损等有关的各种因素,并进行改进结构设计和研究应用新材料、新工艺等。缸套一般是在边界润滑条件下工作的。构成缸套大修和更换的因素如下:1.机械磨损金属的加工表面,即使是经过珩磨的表面,从微观上看总是凸凹不平的,
Since the inner surface of the cylinder liner is the key factor that determines the length of the engine overhaul interval, various countries have begun to pay attention to various factors related to cylinder liner wear and tear since the beginning of this century, and have made improvements in structural design and research and application of new materials and new Technology and so on. Cylinder liner is generally working under boundary lubrication conditions. Constitute a liner overhaul and replacement of the following elements: 1. Mechanical wear Metal machining surface, even after honing the surface, from the microscopic point of view is always uneven,
