A thermodynamic analysis of the rotary-vee internal combustion engine

Abstract

The rotary-vee is a novel and unusual two-stroke cycle internal combustion engine. The rotary-vee engine is unique in that the combustion chamber and port design is very similar to a reciprocating two stroke engine, however, all of the components have rotary motion. A thermodynamic simulation of the rotary-vee internal combustion engine was developed and used, to explore the thermodynamic advantages or disadvantages of the rotary-vee engine, as compared to a reciprocating piston engine. Although the rotary-vee possesses some advantages such as rotary motion and piston ring sealing, the results indicate that the rotary-vee may have a I to 4 percent loss in work output as compared to a reciprocating piston engine of equal cylinder displacement. In addition, the geometry of the rotary-vee engine was described and analyzed. The engine is also classified relative to other positive displacement engines.
