从进口ND_5型机车及我国大功率机车发展的需要出发,对铁路内燃机车四代油进行了深入研究。全部试验均以美国GE公司认可的美国雪佛龙化学公司进口添加剂调制的现用四代油作对比油,参照美国机车维修者协会(LMOA)四代油的标准及GE公司机车制造厂超性能油的技术条件,根据实验室理化性能试验、模拟评定试验、多种发动机台柴试验和12台ND_5型机车(每种油三台车)一年的现场行车试验,得出结论:研制的3种试验油达到了国外80年代四代油的水平,填补了我国新型四代柴油机润滑油的空白。文章最后指出了,3种试验油在进口机车与国产机车上的推广意见,并对四代油的更新换代所带来的经济效益进行了预测。
Starting from the need of importing ND5 locomotive and the development of our country’s high-power locomotive, the author studies the four generations of diesel locomotive oil. All tests are based on the current four generations of oil prepared by imported chemico-chemical additives imported from Chevron Chemical Company of the United States GE as comparative oil. According to the LMOA standards and GE’s locomotive manufacturer’s super performance Oil technical conditions, according to the laboratory physical and chemical properties of the test, the simulation test, a variety of engine diesel test and 12 sets of ND5 locomotives (three for each oil) on-site driving test, concluded: developed 3 The test oil has reached the level of foreign oil of the fourth generation in the 1980s to fill the blank of the new fourth generation diesel oil in our country. Finally, the article points out the promotion opinions of the three kinds of test oils on imported locomotives and domestic locomotives, and predicts the economic benefits brought by the upgrading of the fourth generation of oil.
