Multi-purpose internal combustion engine

Claim 1

AN INTERNAL COMBUSTION ENGINE ADAPTED TO OPERATE SELECTIVELY, AT THE SAME COMPRESSION RATIO, WITH GASOLINE OR DIESEL FUEL INJECTION, COMPRISING CYLINDER MEANS, PISTON MEANS WITHIN SAID CYLINDER MEANS AND DELIMITING IN PART A COMBUSTION CHAMBER WHICH IS AT LEAST APPROXIMATELY AXIALLY SYMMETRICAL, MEANS FOR PRODUCING AN AIR VORTEX WITHIN SAID COMBUSTION CHAMBER ABOUT AN AXIS EXTENDING ESSENTIALLY IN THE CYLINDER LONGITUDINAL DIRECTION, MULTIAPERTURED INJECTION MEANS FOR SUBSTANTIALLY SIMULTANEOUSLY INJECTING FROM WITHIN THE AREA OF SAID FIRST-MENTIONED AXIS ESSENTIALLY RADIALLY DIRECTED FUEL JETS INTO SAID COMBUSTION CHAMBER SPACED SUBSTANTIALLY OVER THE ENTIRE COMBUSTION CHAMBER CROSS SECTION AS SEEN IN A PLANE PERPENDICULAR TO SAID AXIS, AND MEANS ENABLING APPLIED IGNITION OPERATION OF SAID ENGINE WITH GASOLINE FUEL INJECTION WHILE ENABLING AUTO-IGNITION OPERATION OF SAID ENGINE WITH DIESEL FUEL INJECTION, THE COMPRESSION RATIO OF SAID ENGINE, WHICH REMAINS CONSTANT FOR GASOLINE AND DIESEL FUEL OPERATION, BEING SELECTED TO BE RELATIVELY LOW FOR DIESEL ENGINES AND RELATIVELY HIGH FOR OTTO ENGINES TO ENABLE SAID ENGINE TO OPERATE WITH APPLIED IGNITION IN CASE OF GASOLINE FUEL INJECTION AND WITH SELF-IGNITION IN CASE OF DIESEL FUEL INJECTION, THE STRENGTH OF SAID AIR VORTEX AND THE PENETRATING POWER OF THE ESSENTIALLY RADIALLY DIRECTED FUEL JETS BEING SO MATCHED TO ONE ANOTHER THAT SAID FUEL JETS FAIL TO REACH THE CYLINDER WALLS BUT ARE DEFLECTED PRIOR THERETO ESSENTIALLY IN THE CIRCUMFERENTIAL DIRECTION BY SAID AIR VORTEX.
