EFFECT OF BIODIESEL ON OXIDATION RESISTANCE OF ENGINE OIL

Abstract

Abstract: The research status of effect of biodiesel on anti-oxidation performance of engine oils was introduced, and a biodiesel formula with the same rigor as CEC L-109 was independently designed to evaluate the anti-oxidation performance of engine oils. The effects of palm oil biodiesel, gutter oil biodiesel and self-designed biodiesel on the anti-oxidation performance of engine oil according with ACEA specification and API specification were investigated. The results showed that the higher the content of unsaturated fatty acids in biodiesel, the greater the effects on anti-oxidation performance of biodiesel. The effect of biodiesel prepared from different raw materials on the anti-oxidation performance of engine oil was similar, which was mainly related to the content of unsaturated fatty acids in biodiesel, the type of based oil and the content of additives in engine oil.

Key words: engine oil, biodiesel, oxidation resistance
