1 前言内燃机车柴油机机油稀释是国产内燃机车柴油机的通病。机油稀释的主要原因是喷油器、活塞、高压油管等柴油机部件故障 ,使未燃烧或未完全燃烧的柴油进入机油 ,使机油的运动粘度、闪点等理化指标下降而报废 ,从而浪费了大量的优质机油。同时 ,由于机油稀释造成柴油机正常
1 Introduction diesel locomotive diesel engine oil dilution is a common problem diesel locomotive. Oil dilution is mainly due to failure of diesel engine parts such as fuel injectors, pistons and high-pressure fuel pipes, so that unburned or incompletely-burned diesel oil enters the oil, which degrades the kinematic viscosity and the flash point of the oil and discards a large amount of physical and chemical indicators The quality of oil. At the same time, the diesel engine is normal due to oil dilution
