To deliver the fuel into the combustion zones of a direct injection four-stroke motor, during the start and/or warming-up phase additional fuel is injected into the cylinders and ignited while the outlet valve is opened. The ignition of the additional fuel feed is before the piston reaches the top dead center near the change over, and the additional feed starts after the outlet valve maximum opening point.
