摘　　要：根据甲醇汽油对发动机润滑油抗磨性影响的要求,选用T203、T706、MoDDP抗磨添加剂,开发出一种甲醇汽油发动机润滑油;通过四球机试验考察各单剂对基础油抗磨性的影响,并采用正交试验方法分析各剂之间的复合性能。试验结果表明:当添加剂T203、MoDDP、T706的配比为1.5∶1.5∶0.4时,研制油的复合抗磨性能最佳。Based on the requirements of methanol and gasoline convertible-fuel on wear resistance of lubricating oil, a methanol and gasoline convertible-fuel engine oil was developed by selecting T203, T706 and MoDDP as anti-wear addi- tives. The effect of four kinds of additives on the base oil was studied by four-ball tester respectively, and their compounding properties were analyzed though orthogonal experimental design. The test results show that when the ratio of T203, MoDDP and T706 is 1.5： 1.5：0. 4,the tested oil has the best anti-wear performance.
