ABSTRACT:
This invention relates to a rotary engine that functions without internal gears, off-centered rotors, reciprocating pistons, crankshafts, trochoidal chamber, chains, nor belts. (While no claim can be made on missing parts, the fact that such conventional parts are missing is one of the reasons that make this invention different from prior arts, and, therefore, it is so listed.) The preferred embodiment, comprising multipurpose rotors, paired dams, combustors, turbines, etc., could be made small enough to run a lawn mower or large enough to fly a big air plane. It uses a modified form of combustors, wherein combustion takes place amid ample air, thus promoting a fuller combustion of fuel at a lower temperature than in conventional rotary and reciprocating piston engines. Consequently, this invention has a surprisingly low amount of CO, NO.sub.x, and unburnt hydrocarbons in its exhausts. Each rotor has a compressing head, oil reservoir, turbine blades protruding from its radial side, and cooling means in its central part, and serves as a compressor, flywheel, lubricator, engine cooler, and turbine. Exactly at the end of each compressing cycle, each rotor releases its compressed gasses to the combustors, wherein gasses are either mixed and ignited, or directly ignited. The resulting expanding gasses passing through the combustors' exhaust nozzles strike the turbines, causing the latters to spin. Each turbine is attached to a rotor's radial side, and each rotor, in turn, is keyed to the central power output shaft.
