Piston rings play a crucial role in the IC engines. They act as a media between the piston and the cylinder liner. The piston rings play a major role when the piston is in reciprocating motion. The rings should withstand the high temperature and pressure during the combustion cycle. In this research project we are concentrating in three fields: the chemical, metallurgical and mechanical. We are considering 3 top rings with different coatings. Chrome, Molychrome and Molychrome ceramic (MCC) [1]. These rings are subjected to wear test and the results obtained are compared to find out the ring with least wear rate. The ring with MCC coating is then fixed in an engine test ring and the various engine parameters are recorded.

Keywords : Chrome, Molychrome, MCC, pin on disk equipment, engine test bed, rate of wear.
