Claims

1. AN INTERNAL COMBUSTION ENGINE COMPRISING, A CYLINDER, A PISTON MEMBER RECIPROCATING IN SAID CYLINDER, A CYLINDER HEAD MEMBER ENCLOSING SAID CYLINDER TO FORM A COMBUSTION CHAMBER, A CAVITY FORMED IN ONE OF SAID MEMBERS, SAID CAVITY OPENING THROUGH A THROAT INTO THE SQUISH AREA BETWEEN SAID PISTON AND SAID CYLINDER HEAD MEMBERS, SAID CAVITY HAVING SUFFICIENT VOLUME TO PROMOTE A SQUISH INDUCED AIR TRANSFER FROM SAID SQUISH AREA INTO SAID CAVITY AS THE PISTON MEMBER APPROACHES ITS TOP DEAD CENTER POSITION, A FUEL INPINGEMENT SURFACE IN SAID COMBUSTION CHAMBER COMMUNICATING AT ONE SIDE WITH SAID SQUISH AREA AND AT ANOTHER SIDE WITH SAID THROAT FOR CAUSING A PORTION OF THE SQUISH INDUCED AIR TRANSFER TO TRAVERSE SAID FUEL IMPINGEMENT SURFACE, A FUEL INJECTION NOZZLE HAVING AT LEAST ONE DISCHARGE ORIFICE DISPOSED TO DEPOSIT A SUBSTANTIAL PORTION OF ITS FUEL SPRAY UPON SAID FUEL IMPINGEMENT SURFACE DURING INJECTION, THE SQUISH INDUCED AIR TRANSFER ACROSS SAID FUEL IMPINGEMENT SURFACE BEING ADAPTED TO SWEEP THE DEPOSITED LIQUID FUEL INTO SAID CAVITY, AND AN IGNITION DEVICE POSITIONED IN THE PATH OF THE SWEPT FUEL PARTICLES AND CONTIGUOUS TO SAID FUEL IMPINGEMENT SURFACE FOR IGNITING THE FUEL PARTICLES.
