Abstract

A method and apparatus for controlling a solenoid-valve-controlled fuel-metering system, especially for a diesel internal combustion engine, provide an electronic control device, which calculates a starting time and/or a stopping time for a solenoid valve based upon at least one of an injection start variable and a feed duration variable. An angle variable is calculated based upon a time variable, taking into consideration at least one of an instantaneous rotational speed and a correction angle.
