ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2000 - IPC

FIELD: transport engineering; road and air vehicles. SUBSTANCE: proposed engine has housing with epitrochoidal surface, fuel injection nozzle, intake and scavenging-filling ports. Two-peak rotor executes planetary motion in housing. Synchronization of rotor movement and eccentric shaft rotation is provided by means of synchronizing bushings. Synchronizing bushings with parallel side faces on ends getting into rotor end face slots are installed in cylindrical cavities of end face covers. Synchronizing bushings are in contact through flats with side parallel walls whose direction coincides with direction of longitudinal axes of end face synchronizing slots of rotor passing through center of rotor. Side parallel walls of rotor synchronizing slots are connected by arcs made to radii corresponding to radius of circumference of synchronizing bushing cylindrical surface and providing displacement of rotor synchronizing slots relative to synchronizing bushings when large diameter eccentric shaft is used. EFFECT: increased power output, service life, reliability and economy of engine. 2 dwg
