Analytical and Experimental Investigation of Ringless Piston Concept.
Abstract
The purpose of this project was to analytically and experimentally investigate the concept of a ringless piston internal combustion engine. A joint objective was to design, build, and test a ringless piston to improve ringless piston engine performance. A computer model was developed to predict ringed and ringless piston engine performance. Experimental performance data were then collected by operating a small, liquid cooled, two stroke gasoline engine with and without the piston ring on the stock aluminum and Southwest Research Institute prototype steel piston. The experimental performance data were then compared with the results of the computer model. The results showed that a piston engine can operate without piston rings. Keywords: Engines, Piston, Piston rings, Compound engines, Reciprocating engines.
