New Developments in Piston Rings for the Modern Diesel Engine

This paper presents unpublished data on new coating developments, new piston ring designs, and design considerations for the modern diesel engine. Data on the current state of the art of compression ring coatings along with technical data on new generation coatings are included as well as data on ring designs and/or design considerations which may be used to improve engine performance and life with respect to blow-by and oil control.
