Beschreibung
Zusammenfassung:	In a method and apparatus for controlling the fuel metering for an internal combustion engine, an electrical displacement sensor is used for fuel injection pumps with an injection quantity control element, which is adjusted, via a control lever, proportionally to the electrical displacement sensor, whose displacement change causes an electrical signal proportional to this displacement change, this electrical signal being fed into an electronic control unit for readjusting the injection quantity control element. In order to avoid supply quantity scatter, control can be directed towards a calibration point situated on a supply quantity characteristic of the fuel injection pump, this calibration point preferably being located in the region of the maximum fuel supply quantity, and the output voltage of the electrical displacement sensor can be compared with a specified required value.
