Experimental Wear Study between Piston Ring and Cylinder Liner Pair using Jatropha Oil as Lubricating Oil

This paper reports the experimental study of wear behaviour for the pair of cylinder liner and piston ring. Reciprocating wear process parameters were optimized for minimum weight loss of piston rings, based on the response surface methodology with three process parameters such as load, sliding velocity and quantity of oil. The tests were conducted under two different types of oil such as Jatropha oil and SAE15W40 oil. It is perceived that sliding velocity is the most important factor for influencing weight loss of piston ring under both the oils. The tests under Jatropha oil gives less weight loss of piston rings, when compared with that of under SAE15W40 oil. The experimental results are in exact consonance with the values obtained from the theoretical model.
