A Review of Present information on Piston Ring Tribology 852355

A selected number of papers published within the last five years relating to piston ring tribology research in the areas of friction determination, friction reduction, lubrication, and oil consumption, have been reviewed. Improved ring lubrication models and friction measurement techniques have been developed by various authors. Their efforts have enlarged considerably on our understanding of the main features of ring-cylinder interface friction and lubrication behavior, and the mechanism of engine oil consumption. However, there is still a lack of understanding in matters of quantity and detail. Recommendations for future work are presented.
