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
本文介紹了國內外汽油機油的發展現狀以及發展趨勢，通過分析汽油機主要摩擦副的摩擦磨損特性和潤滑狀態以及汽油機對潤滑油的性能要求，在潤滑理論的指導下和參閱大量資料的基礎上，合理地選擇基礎油和添加劑。本文用均勻實驗設計安排實驗，用逐步回歸技術進行結果處理，分析了基礎油對添加劑的感受性和添加劑之間的配伍性。在重點考察汽油機油低溫性能的基礎上，提出了15w 40sh級汽油機油的優化配方。 -
