ABSTRACT:
In a method for introducing fuel into the combustion chamber of an internal combustion engine wherein compressed gas is drawn from the combustion chamber during the compression phase of a working cycle, mixed with fuel, and injected into the combustion chamber together with the fuel during the subsequent working cycle, an ignitible mixture must be provided at the point where ignition is initiated. To keep together the spray cloud of the fuel-air mixture injected into the combustion chamber while moving it to the point of ignition, the proposal is put forward a complex air flow is generated during the compression phase of the engine which includes first, second and third streams that rotate about rotational axes normal to the cylinder axis and are directed approximately towards the center of combustion in the area of the top of the combustion chamber, the first stream being approximately normal to the second and third streams forming a vortex pair, and the fuel-air mixture is injected into the first stream in the direction of the ignition point.
