Abstract

A method and apparatus for injecting fuel into a combustion chamber of an air compressing, spontaneous ignition, internal combustion engine are provided. An adjustment member of an injector is actuated electrically and is controlled via an electronic circuitry, with the fuel quantity being withdrawn from a pressure chamber. The adjustment member acts upon a release sectional area of a restrictor. An adjustment member in the form of a magneto strictive rod is provided. The release sectional area is controlled by a control voltage, generated by the electronic circuitry, and can be chronologically modulated.
