Fuel injector needle valve in an internal combustion engine is subjected to wear during its working over a period of time. Wear of the needle seat and needle surface is depended on the lubricity of the fuel. Wear caused to any of these surfaces will affect the performance of the engine. In the present work, the friction and wear behaviour of the needle material was studied on a reciprocating wear tester when lubricated with various blends of Karanja oil methyl ester with diesel. A high frequency reciprocating wear tester with a ball on flat geometry was used for the study. Coefficient of friction and cumulative wear depth obtained with various blends were compared. Wear scars on the ball surface and wear tracks on the flat samples were analysed. It was observed that the coefficients of friction as well as wear depth were found to be minimum when 100 % methyl ester was used © 2019 Elsevier Ltd.
