我国铁路从美国进口的420台内燃机车,每年消耗机油3000～4000t,要求应用美国铁路三代或四代机油。现我国铁路机油只相当于二代油的水平,每年因机油添加剂进口耗费大量外汇。为解决进口机车及发展国内大功率机车的需要,铁道部科学院三、四代油专题一行五人于1986年11月赴美国考察、访问了美国雪佛龙化学公司、鲁布瑞佐公司、通用电气公司、美国铁路协会芝加哥技术中心、西南研究所润滑剂评定中心以及美国标准局等单位。
420 sets of diesel locomotives imported from the United States by China’s railways consume 3,000 to 4,000 tons of oil each year and require the U.S. railways to have three generations or four generations of oil. Now China’s railway oil is only equivalent to the level of second-generation oil, imported oil additives each year consume a large amount of foreign exchange. In order to solve the need of importing locomotives and developing domestic high-power locomotives, the three and four generations of oil experts of the Ministry of Railways inspected the United States in November 1986 and visited the United States Chevron Chemical Company, Lubrizol Corporation, General Motors Electric Company, the American Institute of Railways Chicago Technical Center, Southwest Institute lubricant evaluation center and the United States Bureau of Standards and other units.
