Rotary combustion engine with precombustion chamber

Claim 2

A ROTARY INTERNAL COMBUSTION ENGINE HAVING A CYCLE INCLUDING THE FOUR STROKES OF INTAKE, COMPRESSION, EXPANSION AND EXHAUST AND COMPRISING AN OUTER HOLLOW BODY AND AN INNER BODY SUPPORTED FOR RELATIVE TURNING MOVEMENT WITHIN THE OUTER BODY, AND TURNING ON AN AXIS ECCENTRIC OF AN PARALLEL TO THE AXIS OF THE OUTER BODY, SAID BODIES HAVING RESPECTIVE FACING SURFACES DEFINING A PLURALITY OF VARIABLE VOLUME WORKING CHAMBERS, SAID FACING SURFACES COMPRISING THE OUTER SURFACE OF THE INNER BODY AND THE INNER SURFACE OF THE OUTER BODY WHICH INCLUDES A PLURALITY OF ARCHED LOBE-DEFINING PORTIONS SPACED CIRCUMFERENTIALLY ON THE AXIS OF THE OUTER BODY, SAID OUTER SURFACE OF THE INNER BODY INCLUDING A PLURALITY OF APEX PORTIONS SPACED CIRCUMFERENTIALLY ABOUT THE AXIS OF THE INNER BODY, SAID APEX PORTIONS INCLUDING SEALS WHICH EXTEND PARALLEL TO THE AXIS OF THE INNER BODY AND ENGAGE THE INNER SURFACE OF THE OUTER BODY, INTAKE PASSAGE MEANS ARRANGED TO COMMUNICATE WITH THE SPACE BETWEEN THE EXTERIOR OF THE INNER BODY AND INTERIOR OF THE OUTER BODY FOR SUCCESSIVELY FEEDING ALL SAID CHAMBERS AS THE BODIES RELATIVELY MOVE, EXHAUST PASSAGE MEANS ALSO ARRANGED TO COMMUNICATE WITH SAID SPACE, MEANS FORMING A PRECOMBUSTION CHAMBER, A NOZZLE CONNECTED TO SAID MEANS FOR INJECTING FUEL INTO SAID PRECOMBUSTION CHAMBER, AND MEANS IN SAID PRECOMBUSTION CHAMBER FOR IGNITING THE FUEL, SAID OUTER BODY INCLUDING PASSAGE MEANS ADJACENT A LOBE JUNCTION FOR CONNECTING THE PRECOMBUSTION CHAMBER WITH EACH OF THE WORKING CHAMBERS AFTER INTAKE AND BEFORE EXHAUST WHILE WORKING CHAMBER VOLUME IS SIDE OF A LOCATION ALONG THE INNER SURFACE OF THE OUTER SIDE OF A LOCATION ALONG THE INNER SURFACE OF THE OUTER BODY WHERE PRESSURE ON BOTH SIDES OF AN APEX SEAL IS THE SAME AND INCLUDING SEPARATE PASSAGES SPACED APART AT THE INNER SURFACE OF THE OUTER BODY IN THE DIRECTION OF MOTION OF THE INNER BODY FOR CONNECTING ADJACENT WORKING CHAMBERS THROUGH THE PRECOMBUSTION CHAMBER WHEN AN APEX SEAL IS BETWEEN THE SPACED PASSAGES.

Claim 3

A FUEL INJECTION ROTARY PISTON INTERNAL COMBUSTION ENGINE OF THE TYPE IN WHICH FUEL AND AIR ARE INTERMIXED WITHIN THE ENGINE PROPER, WHICH COMPRISES: A FIRST ENGINE MEMBER FORMING AN OUTER ENGINE BODY WITH A MAIN CHAMBER HAVING AN AIR INLET FOR DRAWING IN AIR AND AN EXHAUST GAS OUTLET FOR DISCHARGING EXHAUST GAS, AND A SECOND ENGINE MEMBER ARRANGED WITHIN SAID MAIN CHAMBER AND ROTATABLE RELATIVE TO SAID FIRST ENGINE MEMBER, SAID FIRST AND SECOND ENGINE MEMBERS CONFINING WITH EACH OTHER A PLURALITY OF CONTINUOUSLY VARYING CHAMBER MEANS INCLUDING A COMPRESSION AND COMBUSTION CHAMBER MEANS, SAID SECOND ENGINE MEMBER BEING OPERABLE TO CONVEY AIR DRAWN IN THROUGH SAID INLET TO SAID COMPRESSION AND COMBUSTION CHAMBER MEANS WHILE FORMING THE COMPRESSION AND COMBUSTION CHAMBER MEANS WITH SAID FIRST ENGINE MEMBER, ONE OF SAID ENGINE MEMBERS BEING PROVIDED WITH SEALING EDGES EXTENDING PARALLEL TO THE AXIS OF ROTATION OF SAID SECOND ENGINE MEMBER AND SEALINGLY ENGAGING RESPECTIVE ADJACENT SURFACE PORTIONS OF THE OTHER ENGINE MEMBER FOR SEALING ALL OF SAID CHAMBER MEANS RELATIVE TO EACH OTHER, SAID FIRST ENGINE MEMBER BEING PROVIDED WITH AUXILIARY CHAMBER MEANS AND WITH PASSAGE MEANS LEADING FROM SAID AUXILIARY CHAMBER MEANS INTO SAID CHAMBER MEANS WHICH ARE CONFINED BY SAID FIRST AND SECOND ENGINE MEMBERS FOR PERMITTING AN EXCHANGE OF A TURBULENT FUEL AIR MIXTURE BETWEEN SAID AUXILIARY CHAMBER MEANS AND SAID COMPRESSION AND COMBUSTION CHAMBER MEANS, FUEL INJECTION NOZZLE MEANS LEADING INTO AT LEAST ONE OF SAID TWO LAST-MENTIONED CHAMBER MEANS FOR INJECTING FUEL THEREINTO, THE ENTRANCE OF SAID PASSAGE MEANS INTO SAID CHAMBER MEANS CONFINED BY SAID FIRST AND SECOND ENGINE MEMBERS BEING SO LOCATED WITH REGARD TO SAID SEALING EDGES THAT THE RESPECTIVE SEALING EDGE ADJACENT SAID ENTRANCE WILL IN THE DIRECTION OF ROTATION OF SAID SECOND ENGINE MEMBER PASS BY SAID ENTRANCE AND PERMIT COMMUNICATION BETWEEN SAID PASSAGE MEANS AND SAID COMPRESSION AND COMBUSTION CHAMBER MEANS ONLY SHORTLY BEFORE THE END OF THE DESIRED COMPRESSION OF AIR IN SAID COMPRESSION AND COMBUSTION CHAMBER MEANS, WHEREBY A TURBULENT FLOW OF COMPRESSED AIR INTO AND THROUGH SAID AUXILIARY CHAMBER MEANS WILL BE CREATED.

Claim 4

A FUEL INJECTION ROTARY PISTON INTERNAL COMBUSTION ENGINE OF THE TYPE IN WHICH FUEL AND AIR ARE INTERMIXED WITHIN THE ENGINE PROPER, WHICH COMPRISES: A FIRST ENGINE MEMBER FORMING AN OUTER ENGINE BODY WITH A MAIN CHAMBER HAVING AN AIR INLET FOR DRAWING IN AIR AND AN EXHAUST GAS OUTLET FOR DISCHARGING EXHAUST GAS, AND A SECOND ENGINE MEMBER ARRANGED WITHIN SAID MAIN CHAMBER AND ROTATABLE RELATIVE TO SAID FIRST ENGINE MEMBER, SAID FIRST AND SECOND ENGINE MEMBERS CONFINING WITH EACH OTHER A PLURALITY OF CONTINUOUSLY VARYING CHAMBER MEANS INCLUDING A COMPRESSION AND COMBUSTION CHAMBER MEANS, SAID SECOND ENGINE MEMBER BEING OPERABLE TO CONVEY AIR DRAWN IN THROUGH SAID INLET TO SAID COMPRESSION AND COMBUSTION CHAMBER MEANS WHILE FORMING THE COMPRESSION AND COMBUSTION CHAMBER MEANS WITH SAID FIRST ENGINE MEMBER, ONE OF SAID ENGINE MEMBERS BEING PROVIDED WITH SEALING EDGES EXTENDING PARALLEL TO THE AXIS OF ROTATION OF SAID SECOND ENGINE MEMBER AND SEALINGLY ENGAGING RESPECTIVE ADJACENT SURFACE PORTIONS OF THE OTHER ENGINE MEMBER FOR SEALING ALL OF SAID CHAMBER MEANS RELATIVE TO EACH OTHER, SAID FIRST ENGINE MEMBER BEING PROVIDED WITH AUXILIARY CHAMBER MEANS AND WITH PASSAGE MEANS LEADING FROM SAID AUXILIARY CHAMBER MEANS INTO SAID CHAMBER MEANS WHICH ARE CONFINED BY SAID FIRST AND SECOND ENGINE MEMBERS FOR PERMITTING AN EXCHANGE OF A TURBULENT FUEL AIR MIXTURE BETWEEN SAID AUXILIARY CHAMBER MEANS AND SAID COMPRESSION AND COMBUSTION CHAMBER MEANS, FUEL INJECTION NOZZLE MEANS LEADING INTO AT LEAST ONE OF SAID TWO LAST-MENTIONED CHAMBER MEANS FOR INJECTING FUEL THEREINTO, THE ENTRANCE OF SAID PASSAGE MEANS INTO SAID CHAMBER MEANS CONFINED BY SAID FIRST AND SECOND ENGINE MEMBERS BEING SO LOCATED WITH REGARD TO SAID SEALING EDGES THAT THE RESPECTIVE SEALING EDGE ADJACENT SAID ENTRANCE WILL IN THE DIRECTION OF ROTATION OF SAID SECOND ENGINE MEMBER PASS BY SAID ENTRANCE AND PERMIT COMMUNICATION BETWEEN SAID PASSAGE MEANS AND SAID COMPRESSION AND COMBUSTION CHAMBER MEANS ONLY SHORTLY BEFORE THE END OF THE DESIRED COMPRESSION OF AIR IN SAID COMPRESSION AND COMBUSTION CHAMBER MEANS, WHEREBY A TURBULENT FLOW OF COMPRESSED AIR INTO AND THROUGH SAID AUXILIARY CHAMBER MEANS WILL BE CREATED.
