摘 要: | 介绍了中国石化石油化工科学研究院开发的SM/GF-4汽油机油复合添加剂和油品配方技术。采用该技术生产的油品模拟试验性能和物理化学性质均能满足SM/GF-4规格指标要求,该油品配方中复合添加剂的加剂量(w)为7.5%。采用MTM和HFRR摩擦磨损试验对新开发的SM/GF-4 5W-30油品进行了减摩和低温抗磨性能研究,发现油酸甘油酯减摩剂老化后仍然具有较好的减摩性能。采用X射线光电子能谱分析了该油品进行程序IIIG高温抗氧化发动机台架试验后的活塞沉积物成分,结果表明活塞沉积物中除积炭外,主要含有发动机油的硫酸盐灰分。

DEVELOPMENT OF SM/GF-4 GASOLINE ENGINE OIL |
| |
Abstract: | SM/GF-4 additive package and SM/GF-4 5W-30 gasoline engine oil formulation technology were developed by SINOPEC Research Institute of Petroleum Processing. The simulation tests and physical and chemical properties of the oil met all requirements of SM/GF-4 specifications. The dosage of the SM/GF-4 additive package was 7.5% (w). Through MTM and HFRR friction and wear tests, the anti-friction and low temperature anti-wear properties of the newly developed SM/GF-4 5W-30 oil were evaluated. Glycerol monoolete additive still had good friction reducing performance after aging. The piston deposit after sequence IIIG engine test, which evaluate the high temperature oxidation property of engine oil, was studied by X-ray photoelectron spectroscopy. The results showed that the piston deposits mainly contained sulphated ash of engine oil besides carbon deposit. |
