Exhaust manifold system for internal combustion engines

Claim 1

EXHAUST MANIFOLD SYSTEM FOR A MULTICYCLINDER COMBUSTION ENGINE COMPRISING: AN AXIALLY ELONGATED CYLINDRIAL RECEIVER DEFINED BY A GENERALLY CONTINUOUS BODY WALL WHICH FORMS THEREWITHIN A CONTINUOUS UNDIVIDED FLOW CHAMBER OF SUBSTANTIALLY CIRCULAR CROSS-SECTION AND OF GIVEN DIAMETER; SAID RECEIVER BEING ADAPTED FOR GAS FLOW THERETHROUGH TOWARD A DOWNSTREAM END THEREOF; A TURBINE MEANS DISPOSED AT SAID DOWNSTREAM END OF SAID RECEIVER; SAID TURBINE MEANS INCLUDING A ROTATABLE PORTION; AT LEAST ONE EXHAUST PIPE CONNECTING EACH CYLINDER OF SAID MULTICYLINDER COMBUSTION ENGINE TO SAID RECEIVER EACH OF SAID EXHAUST PIPES PASSING THROUGH SAID RECEIVER BODY WALL AND HAVING AN OUTLET END DISPOSED WITHIN SAID UNDIVIDED FLOW CHAMBER; SAID EXHAUST PIPES BEING ARRANGED IN SPACED DISPOSITION AXIALLY OF SAID RECEIVER AND HENCE PASSING THROUGH SAID BODY WALL AT LOCATIONS SUCCESSIVELY SPACED ALONG THE ELONGATED LENGTH THEREOF; SAID EXHAUST PIPES HAVING DIAMETERS WHICH ARE A MINOR FRACTIONAL DIMENSION OF SAID GIVEN DIAMETER; EACH OF SAID EXHAUST PIPES HAVING ITS AXIS EXTENDING FROM THE OUTLET END THEREOF TOWARD ITS CONNECTED CYLINDER; EACH OF SAID EXHAUST PIPE AXES BEING DISPOSED AT AN ANGLE OF LESS THAN 90* TO SAID RECEIVER AXIS; SAID EXHAUST PIPE OUTLET ENDS BEING POSITIONED SO THAT GAS FLOW THEREFROM WILL HAVE A DIRECTIONAL COMPONENT TOWARD THE DOWNSTREAM END OF SAID RECEIVER, WHEREBY THE CUMULATIVE GAS FLOW THROUGH SAID EXHAUST PIPES CREATES A SPIRAL-SHAPED ROTATIONAL VELOCITY FIELD WITHIN SAID FLOW CHAMBER WHICH TRANSVERSE TO SAID TURBINE MEANS TO ROTATE THE ROTATABLE PORTION THEREOF.
