由于现代柴油机热参数大量提高,活塞环和气缸套的不正常磨损随之而增加,特别对大型二冲程回流扫气柴油机,缸内温度高,润滑条件差,磨损更大。为防止活塞环和汽缸套的正常磨损,苏尔寿柴油机所采取的措施是:一、改进气缸滑油供应,使缸套表面保持油膜状态从 RND-M 型机起除缸套上部原有八个注油孔外,为了改善排气口附近滑油不足的状 Due to the large increase of thermal parameters of modern diesel engines, the abnormal wear of piston rings and cylinder liners increases. Especially for large two-stroke backflow scavenged diesel engines, the cylinder temperature is high, the lubrication conditions are poor, and the wear is even greater. In order to prevent the piston ring and cylinder liner normal wear and tear, Sulzer diesel engine measures taken are: First, to improve the cylinder oil supply, the cylinder liner to maintain the film surface state from the RND-M-type machine to remove the upper part of the original liner A hole in the oil, in order to improve the lack of oil near the exhaust port shape
