Title: Method of making a rotary engine rotor and bearing structure

Abstract: A method of making a rotary engine internal fixed bearing surface and rotor for rotating about the fixed bearing surface, where the rotary engine combustion chamber is shaped in the form of a two arch epitrochoidal line and the rotor has three apexes. The fixed bearing surface is constructed with an elliptical cross section and the rotor has an internal bearing surface in the form of a regular triangle, wherein the method of constructing the fixed bearing surface is derived from the rotor regular triangle bearing surface, so as to permit no loading between the rotor apexes and the engine combustion chamber walls.
