Abstract
An apparatus for generating a fuel quantity signal in an injection pump is proposed, which is provided with a pump piston deflected by a cam disk which aspirates fuel out of a fuel inlet conduit provided with a magnetic valve and expresses it into a supply line. The metered fuel quantity is obtained on the basis of a metering onset signal and an end-of-metering signal, the first being generated by a position-sensor apparatus cooperating with the pump piston and the second being derived from the voltage applied at the magnetic valve.
