Abstract

A fuel injection pump having a hydraulic injection onset adjuster, an rpm governor with at least one member operating in accordance with load, and a full-load stop of the governor which limits the maximum injection quantity is proposed, in which between the full-load stop and the governor member adjustable in accordance with load a switch is provided, which switch upon a change from full load to partial load triggers a magnetic valve, to thereby effect a shift of the injection onset toward "late". The magnetic valve, to this end, engages the hydraulic control of the injection adjuster.
