    摘要: An ignition device for a rotary piston engine includes a glow plug which is mounted at an ignition port formed in an engine housing to communicate with a combustion and operation chamber and which, when electrically powered, is heated to red hot to ignite an air-fuel mixture in the combustion and operation chamber. The glow plug ignites the air-fuel mixture through a communicating port which is formed to face the combustion and operation chamber and which has a smaller aperture area than the cross-section area of the ignition port.

    摘要: A rotary piston engine comprises a housing having a trochoidal peripheral wall and side walls on both sides thereof, a rotor adapted to perform a planetary rotary motion along the inner surface of the peripheral wall and intake and exhaust ports formed in the housing. The engine performs intake, compression, combustion and exhaust of a working fluid by means of the planetary rotary motion of the rotor. An air injection port is formed in the peripheral wall of the housing between the exhaust port and a portion of the peripheral wall through which the minor axis of the trochoidal curve extends. A means is provided to supply air through the air injection port into the housing to prevent recirculation of exhaust gas into the intake chamber of the engine, stratify an air-fuel mixture of a richness appropriate for spark ignition and a lean air-fuel mixture with a resultant combustion of the stratified mixtures and reduce harmful exhaust gases, particularly, hydrocarbon (HC) and carbon monoxide (CO) by means of the engine operation with a relatively lean air-fuel mixture.
