Abstract: Internal combustion engines are an integral part of society today. Their efficient operation and function are paramount to their design. By improving the function of the engine, it may be possible to increase the potential available power output to the flywheel. By redesigning the engine head and replacing the traditional poppet valve system with a novel rotary valve system, the incoming fuel and air mixture can more easily flow into the cylinder. In turn, this will increase the amount of fuel and air present during combustion, and more evenly distribute the pressure of the fluid throughout the cylinder. The resulting combustion process will then burn more consistently and produce more power at the piston face. It was found that not only does the rotor valve system increase the available pressure at the piston face, but also the internal energy in the working fluid during combustion. The rotor valve system also alleviated flow restriction issues during the intake and exhaust strokes.
