ABSTRACT:
In a process for controlling the fuel injection quantity for an internal-combustion engine in a vehicle via an electronic control unit, the actual angle of the crankshaft is detected and, as a function of the actual angle, of a defined fuel injection time and of a defined injection end angle, the required fuel injection starting angle of the crankshaft or the required injection starting point in time for a certain cylinder is determined. The injection is carried out in a time-controlled manner by triggering an injection valve, which is assigned to the certain cylinder, for the defined fuel injection time to an actual injection end angle. Furthermore, while maintaining the defined injection end angle, a short pulse is defined in the control unit as an additional fuel injection time for the certain cylinder if the actual injection end angle is before the defined injection end angle.
