Analysis of 40% Blend of Different Biodiesel on Tribological Property of IC Engine Components

In diesel engine, only air is compressed by the piston and the fuel is injected into the chamber towards the end of the compression stroke. Friction, wear and lubrication are the fields of interest in the study of tribology. The friction is the resistance offered by one solid body to the motion of other solid body. When two mating surfaces moving under the force, the actual material removal takes place and hence results in reduction in the material. This leads to the error in operation. Lubrication is the act of protection against friction and is essential for minimized sliding friction. Analysis is carried out using the different blends of biodiesel considered for the experiments to investigate the variation of surface roughness (Ra) value (in microns) for the IC engine components. The blend of 60% Diesel + 40% Hippe oil has better lubrication properties exhibited as compared to diesel and other biodiesel blends considered.
