Abstract: A rotary internal combustion engine having an even number of rotors planetating relative to and cooperating to drive a crankshaft within an engine housing. An axially extending auxiliary chamber is provided in the housing with each end connecting with a corresponding separate engine rotor cavity through an ignition throat passage. A piston freely reciprocates within the chamber dividing it into separate precombustion chambers for the corresponding rotor cavities. The precombustion chambers receive a rich air fuel charge which is ignited and expands into their corresponding rotor cavity igniting a main air fuel charge. The free piston is responsive to pressure differentials existing between the rotor cavities in which the rotors are phased to provide specific pressure differentials reciprocating the piston after ignition in each cavity. Movement of the piston in response to the pressure differentials is effective to sweep out the burned gases in the particular precombustion chamber into the rotor cavity. The rotor them moves the burned gases discharging them through the engine exhaust system.

Abstract: A rotary combustion engine arrangement having a first stage rotary engine section in which a rich air-fuel mixture is spark ignited with the hot combustion gases thereof directed to provide jet ignition for a second stage rotary engine section that inducts fresh air and the rich exhaust products from the prechamber section.
