Wear behavior on the Leading edge and Trailing edge of the top piston ring of the IC Engine

Abstract

Wear is a ubiquitous phenomenon in a mechanical system. The ambiguity of its behavior in
components makes quantification of wear further complicated. A piston ring of an IC engine faces the
same predicament during performance. Scholars have tried to model wear with some assumptions and
approximations. Researchers have modeled wear loss on the piston ring using the total loss of weight
due to wear, depth of metal removed due to wear, volume loss due to wear with an inherent
assumption that wear is uniform along the circumference of the piston ring. This study has compared
the percentage volume loss due to wear on the leading edge of the piston ring to the wear on the
trailing edge of the piston ring along the circumference of the piston ring. Measurement of percentage
volume loss due to wear along the circumference of the piston ring has been presented by Niralgikar
and Bulsara [7]. The authors, in this study, have observed that the wear on the leading edge of the
compression piston ring of an I C engine is more than the trailing edge of the piston ring
