【摘要】 用模拟MS程序ⅢD和ⅤD的模拟试验机研究了抗氧剂的用量、不同类型清净剂的配比及无灰分散剂与清净剂的配比对内燃机油清净性的影响。在此基础上 ,用 5 .9%的复合剂量成功调制了磷含量为 0 .11%、可在加装催化转化器的车辆上使用的SF/CC 40通用内燃机油。该油通过了理化性能评定和标准发动机台架评定 ,符合SF/CC 40通用内燃机油的技术指标更多还原

【Abstract】 The effects of different kinds of antioxidants, detergents, detergent/ashless dispersant, and their dosages on the engine oil detergency were studied using laboratory testers simulating MS sequence ⅢD and ⅤD tests. The test result showed that SF/CC40 engine oil with phosphorus content less than 0.11% was successfully formulated by adding 5.9% dosage additive package, which can be used in cars with catalytic converters. The physico chemical evaluation and rig test showed that the said engine oil met the specification of SF/CC40.更多还原
