Tribological Performance Evaluation of Biodiesel Distilled Residue Blended with Fossil Diesel

Abstract:

In this work, distilled residues from biodiesel of waste cooking acids methyl esters (WCME), was blended with fossil diesel in different ratios (D100/DR2/DR5/DR10/DR20) as testing fuels. The tribological performance of the blended oils was evaluated using a reciprocating cylinder-on-flat wear test rig (Cameron-Plint TE-77) at two temperatures (room temperature and 80°C). After the wear test, the wear depth of each tested specimen was determined using a profile meter and the worn surface was observed using a scanning electron microscope (SEM). Each worn surface was also examined using an energy dispersive spectrometer (EDS) to identify any surface film. The experimental results show that the tribological performance of the DR20 was superior to that of the other test oils. The lubricity of the test sample increased with the proportion of distilled residue, owing to the quantity of the methyl esters in the sample.
