<p>A rotary engine utilizes an expansion chamber (18) and crescent piston (82) to capture the energy of expanding combustion gases through out substantially all of each revolution of the piston. The movement of the crescent piston is guided by the combined action of a hub (80) having a saddle (84) supporting the piston (82) and a can track (72). Fuel is burnt in a separate combustion chamber (14), charged coaxially mounted compressor (20) and control a pass gate sentry valve (44). The rotary engine is cooled by an internal coolant injection system. Coolant solution contains an alkaline reagent to react with and neutralize acidic components of the combustion gases, which would otherwise remain in the exhaust and contribute to air pollution. The rotary engine is adaptable to compression ignition fuels and spark ignition fuels. The rotary engine is constructed of conventional metallic materials as well as composites and ceramics.</p> |
