Additionally, for an electronic regulation of the total injection quantity, a pre-stroke (hv) is provided, which is determined by a first valve and which, under the control of a second, electrically controlled valve connected to the output side of the first valve, is added to the basic supply stroke in a variably effective manner in terms of injection. Thus the fuel injection quantity can be regulated within the context of the fuel injection quantity difference resulting from the pre-stroke.
