高性能全合成SN 0W-40汽油机油自主技术的开发

The Development of High Performance Full Synthetic SN 0W-40 Gasoline Engine Oil with Independent Intellectual Property

中国石化石油化工科学研究院开发完成了采用RIPP SN自主复合剂调配的SN 0W-40大黏度跨度全合成发动机油技术,发挥添加剂之间的协同效应,充分满足涡轮增压直喷发动机使用润滑油所要求的苛刻抗氧化性能和控制黏度增长能力,实现大幅延长换油期,具有优异的活塞清净性、抗磨性能。RIPP SN 0W-40油品通过了SN规格要求的程序ⅢG、ⅢGA、ⅢGB、ⅣA、ⅤG和Ⅷ发动机台架试验评定,理化指标符合SAE J 300要求,性能大幅超越SN规格要求。

The formulation technology of SN 0W-40 full synthetic and large viscosity span engine oil,with its own independent intellectual property rights,has been successful developed by RIPP of SINOPEC. The synergistic effect of high-performance additives has produced the great anti-oxidation property to meet the severe requirement by turbocharged direct injection engine. Using the lubricant can achieve the very limited viscous growth during the use period,thus greatly prolonging the oil-changing period. Furthermore,it can contribute to the excellent piston cleanliness and the anti-wear properties. RIPP SN 0W-40 engine oil technology has passed all evaluation engine tests which required by SN specifications,including sequence ⅢG,ⅢGA,ⅢGB,ⅣA,ⅤG and Ⅷ engines. Its physical and chemical performances meet the requirements of SAE J 300,and its performance greatly exceeds the requirements of SN specification.
