Improved Military Standard Piston Rings for Industrial Gasoline Engines 620276

This paper discusses the experimental work that produced a revised military standard piston ring (conformable steel-rail oil control ring) with improved oil consumption and wear characteristics. The testing of these parameters was accelerated by the use of radio-tracer techniques. The effects of variables such as engine speed, load, jacket temperature, air-fuel ratio, intermittent starts and stops, and cyclic load operation is described. Performance characteristics of the present standard and experimental piston rings are included.
