Its s applicable for metallurgy , machinery , oil field , chemical engineering , mine , electricity , traffic and manufacturing to filter hydraulic oil , hydraulic transmission oil , gear oil , gasoline engine oil , diesel engine oil , compressor oil , freezer oil , heat treatment oil , ect 广泛适用于冶金机械油田化工矿山电力交通制造等行业对液压油液力传动油轮油汽油机油柴油机油压缩机油冷冻机油热处理油等的净化处理。
The results show : its quality has already reached the properties of 10w / 30 sg gasoline engine oil ; both the green lubricating oil and its basic oil are biodegradable ; the biodegradability of the latter is superior to the former obviously . therefore function additives suppress the biodegradability of the green lubricating oil 结果表明：其质量水平已达到10w 30sg汽油机油的使用性能要求；绿色润滑油及其基础油都是可生物降解的，基础油的生物降解性明显优于绿色润滑油，由此可见各功能添加剂的加入抑制了绿色润滑油的生物降解性。
The results show that antiwear and friction - reducing abilities of ultrafine ws2 powders in petrol engine oil are excellent , and obviously better than that of t302 and mos2 , and through the experiments we know that the 60 # engine oil containing 1 percent of ultrafine ws2 powders has the best lubricating effectiveness 结果表明：二硫化钨粉超细末在汽油机油中具有优良的抗磨减摩性能，其摩擦学性能优于氯化石蜡和二硫化钼，含二硫化钨超细粉末1 %的60号发动机油具有最佳的润滑性能。
The development status and trend of gasoline engine oil at home and abroad are described in this paper . the tribology and lubrication characteristic and lubrication mechanism of the main tribo - pairs of gasoline engine are analyzed simply . in this paper base oil and some additives are chosen reasonably according to the lubricantions principal and a lot of data . the uniform design of experiment is used to arrange multi - level and multi - factor experiments . the stepwise technique is adopted to analyze the result . the sensitivity and compatibility among additives and the base oil are studied by a series of tests . on the basis of analyzing the low temperature capability the optimum of 15w / 40 sh gasoline engine oil is presented . at last , the property of this formulation is evaluated by comparing with the imports . the test result shows that their qualities are equivalent 本文介绍了国内外汽油机油的发展现状以及发展趋势，通过分析汽油机主要摩擦副的摩擦磨损特性和润滑状态以及汽油机对润滑油的性能要求，在润滑理论的指导下和参阅大量资料的基础上，合理地选择基础油和添加剂。本文用均匀实验设计安排实验，用逐步回归技术进行结果处理，分析了基础油对添加剂的感受性和添加剂之间的配伍性。在重点考察汽油机油低温性能的基础上，提出了15w 40sh级汽油机油的优化配方。
