Design, Calculations, and Testing of a New Rotary Internal Combustion Engine
General design features include: nine moving parts, no intake or exhaust valves, a symetric operation resulting in low vibration, continuous ignition (during combustion), and complete combustion exhaust. Analytical calculations were made for an 8-cylinder, 60-lb, prototype which operates on a 4-stroke principle. A dynamic analysis of the pistons indicates that the engine rotation and hence the piston movement does not cause the center of mass nor the moments about the axis of rotation to change with time. As a result the engine has a complete force and moment balance. Combustion calculations were carried out for several thermodynamic cycle models at a stoichiometric fuel-to-air ratio assuming equilibrium chemistry. These calculations indicated ideal horsepower ranged from 38. 7 to 62. 8. Initial prototype testing with combustion verified the thermodynamic cycle redesigned seals. The new engines offers promise as a potential power source for electric generation, transportation, and utility applications.
