THE DEVELOPMENT OF AN ENGINE LUBRICANT CONTAINING SOYBEAN OIL

摘要: of Thesis THE DEVELOPMENT OF AN ENGINE LUBRICANT CONTAINING SOYBEAN OIL The major downfalls vegetable oils, namely soybean oil in this research, are very detrimental to engine lubricant performance. A unique out the boxadditive package is needed compensate for deficiencies. This research searched additive solutions problems oxidation and heat stability, low temperature pumpability, fluid corrosiveness. were then tested preliminary tests. In several formulations developed that passed main test, mini rotary viscometer. lubricants met passing viscosity requirements 60,000 centipoise exhibited no yield stress. formulation was using ASTM D 6594[1], hot tube corrosion bench Sequence VIII test. Acceptable results seen both Oxidation tests used examine stability. Several antioxidants showed improved performance TFOUT induction time mixture those IIIG All formulas failed However, test when decreased from 15 wt % 5 formulations.
