PRECHAMBER ROTARY ICE Russian patent published in 2010 - IPC F02B53/06 F02C5/04 F02C5/12 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production. Proposed prechamber rotary ICE comprises fixed cylindrical stator, rotor with operating zone and end face covers. Combustion mix is prepared and fired in prechamber. Proposed engine comprises also air receiver, air compressor, nozzle and diverter valve, air inlet channel and working and exhaust gas discharge channels built in stator. Air compressor is driven by rotor shaft via gears to generate required pressure in prechamber (to prepare working mix). Prechamber (working mix preparation and combustion chamber) is built in stator. End face covers are furnished with seals. Engine incorporates electrically driven air compressor to generate required air pressure in receiver prior to starting the engine. Engine comprises injector to force fuel into prechamber, and diverter valve shaft drive gears driving said shaft from rotor shaft. Air is forced from air receiver via diverter valve into prechamber sealed by diverter valve arranged to open working gas exhaust from prechamber.

EFFECT: higher reliability, power and efficiency, longer life, simplified design.
