摘　　要：分析了T205、T706、MoDDP作为抗磨剂以及抗氧剂的作用机理。根据CNG/汽油两用燃料发动机对润滑油抗磨性能、抗氧化性能的要求,选择了常用的几种添加剂,通过试验考察了基础油对单一添加剂的感受性,并采用正交试验设计分析了几种添加剂之间的复合性能。试验结果表明,当几种添加剂的配比为:T205M∶oDDPT∶706L∶135∶L57=4∶2∶2∶1∶1时,复合效果最佳。Mechanism of action of T205,T706 and MoDDP as antiwear additive and antioxidant is analyzed.In terms of requirement of CNG/gasoline engine on wear resistance and oxidation resistance of lubricating oil,some conventional additives are selected.Receptivity of the basic oil to a single additive is investigated through tests,and compounding properties between the additives are analyzed through orthogonal experimental design.Test results indicate that when proportioning of additives is ：T205：MoDDP：T706：L135：L57=4：2：2：1 ：1,compounding effective is optimal.
