本文从我国进口ND_5内燃机车及国产大功率内燃机车的需要出发,对铁路内燃机车四代机油进行了深入研究,经过室内理化性能试验、模拟评定、多种发动机台架试验和现场试验,研制出三种配方的铁路四代机油(两种含锌油,一种非锌油)与美国机车维修者协会(LMOA)四代机油的标准,GE公司机车制造厂超性能油的技术条件以及用进口复合剂调制已在ND_5机车上使用的四代机油相比,其各方面性能均达到了国外四代机油的先进水平,可以替代进口四代机油在ND_4、ND_5、东风_6与东风_4C等型机车上应用,填补了我国铁路四代机油的空白。
Based on the need of importing ND5 diesel locomotive and domestic high-power diesel locomotive in our country, this paper deeply studies the four generations of diesel locomotive engine oil. After indoor physical and chemical performance test, simulation assessment, various engine bench tests and field tests, Three formulations of the railway four generations of oil (two zinc-containing oil, a non-zinc oil) and the United States Locomotive Maintenance Association (LMOA) four generations of oil standards, GE locomotive factory super performance oil technical conditions and the use of imported Compared with the fourth generation oil used in ND5 locomotive, the compounding agent has reached the advanced level of the fourth generation oil in foreign countries and can replace the imported fourth generation oil in ND4, ND5, Dongfeng6 and Dongfeng4C etc. Locomotive application, to fill the fourth generation of China’s railway oil blank.
