Sažetak
As renewable and alternative fuel, biodiesel is in the last 15 years the subject of numerous studies, including the research of the influence on engine performances and engine oils. Usage of biodiesel has a number of advantages, however in its application, biodiesel shows also some deficiencies. The application of biodiesel leads to its accumulation in the oil, and thus to the dilution of the oil. Excessive dilution of oil can create problems in the engine operation. Accumulation of biodiesel in the oil leads to oil viscosity fall, formation of oxidation products, deposits and deterioration of low-temperature properties. In this study the influence of biodiesel on the quality of engine oil when conducting high-temperature engine test has been monitored. For this test engine oil of SAE 15W-40 viscosity grade was used. Tested engine oil fulfills quality requirements of leading engine manufacturers, such as: MB, MAN, Volvo. During the test, the engine was run on mixture of diesel and biodiesel.
