由于需要在不增加体积的情况下改善柴油机的可靠性和运转特性,从而促使了增压柴油机的发展。以往所研制的进气柴油机或增压柴油机,不管是湿式缸套还是干式缸套,在缸套-活塞-活塞环的配合中经常会发生(粘着性)擦伤、结胶、缸套内壁磨损得很亮等现象。有时甚至出观磨损率很高和造成咬死的情况。这些问题使制造厂对材料选择和材料质量的要求更为严格,同时要靠采用表面处理(主要是化学热处理)的方法,有时还要靠在润滑油中加入添加剂的办法来解决。
The development of turbocharged diesel engines has been prompted by the need to improve the reliability and operating characteristics of diesel engines without increasing their size. Previously developed intake diesel engine or turbocharged diesel engine, whether it is wet or dry liner cylinder liner, cylinder liner - piston - piston ring often occur with (adhesive) abrasions, adhesive, liner inner wall Wear very bright and so on. Sometimes the appearance of high rates of wear and tear caused by the situation. These problems make the manufacturing plant more stringent material selection and material quality requirements, at the same time rely on the use of surface treatment (mainly chemical heat treatment), and sometimes rely on the lubricant added to the solution to solve.
