Abstract
A fuel injection apparatus for internal combustion engines in which via an electrically controlled valve communication is established between a pump work chamber of a fuel injection pump and a low-pressure fuel chamber, and the switching times and movement times of the valve member of the valve are detected with the aid of a switching position transducer. The actual switching times are used for correction of the control times of the valve and thus for correction of the quantity of fuel attaining injection.
