Gasoline Engine, Diesel Engine Universal Lubricant (sf / Cd 10w/40) Anti-oxidation Stability And Abrasion Resistance

The development status of gasoline and diesel engine oils at home and abroad are described in this paper. The lubrication mechanism of the main tribo-pairs of engine and properties of internal combustion engine oil are analyzed simply. In this paper, the base oil and some additives are chosen scientifically and reasonably. The uniform design of experiment is firstly used for arranging multilevel and multi-factor experiments. The stepwise technique is adopted to put forward the regression equation. The sensitivity and compatibility among additives and the base oil were studied by a series of tests. Interactions among oxidation-corrosion inhibitor, wear- inhibitor and other additives were stress researched. At last, the optimum formulation of 1OW/40 SF/CD internal combustion engine oil was presented. Simultaneously, the property of this formulation was evaluated by being compared with the imports. The test results show that their qualities are equivalent.
