In recent years,the development of China's automobile industry has been changing with each passing day,and it has been realized that upgrading and transforming the engine structure and increasing the compression ratio cannot only improve the power,but also greatly reduce the environmental pollution of exhaust gas through exhaust gas recovery and reuse(EGR)[1].In order to ensure that the engine in the process of operation,always maintain the best state of work,as well as better stability,the selection of the right lubricating oil will be crucial.Improving the quality and performance of the lubricating oil can effectively improve the emission of the engine,will have a direct impact.Especially the viscosity of the lubricating oil and additives will directly affect the fluidity and oxidation resistance of the lubricating oil,and to a large extent affect the performance of the engine.
