摘要/Abstract

摘要： 采用X射线光电子能谱和核磁共振研究程序ⅢH高温抗氧化发动机台架试验后SP/GF-6 汽油机油旧油和活塞沉积物组成，结果表明活塞沉积物除积炭外主要含有发动机油的硫酸盐灰分，对功能添加剂组合对活塞沉积物影响的规律进行了研究总结。根据旧油的抗氧化性能和活塞沉积物的组成指导油品配方技术的优化。采用微牵引力摩擦试验（MTM）仪进行了油品减摩耐久性能研究，MTM 对于发动机油的新油和老化油的节能性能的评价结果可作为一种模拟节能台架试验结果的有效试验方法。

Abstract: X-ray photoelectron spectroscopy and NMR were used to study the composition of old oil and piston deposits in SP/GF-6 gasoline engine oil after high-temperature anti-oxidation engine testing sequence ⅢH. The results showed that piston deposits mainly contained sulfated ash of engine oil in addition to carbon deposits. The influence of functional additive combinations on piston deposits was studied and summarized. Based on the antioxidant properties of old oil and the composition of piston deposits, the optimization of oil formulation technology were guided. MTM was used to study the wear reduction and durability performance of the fuel economy of the oil. The evaluation results of MTM friction test on the energy-saving performance of new and aged engine oil can be used as an effective test method to simulate the results of energy-saving engine tests.

Key words: formulation, additive package, SP/GF-6, deposit, antifriction
