Abstract
The invention is based on a fuel injection pump having an adjuster, actuatable via an adjusting mechanism; the adjusting mechanism has an adjusting piston which is displaceable in a cylinder and is adjustable counter to a restoring force by a pressure fluid. The delivery of pressure fluid to the adjusting piston is controlled via electric valves, and by means of various geometrically defined adjusting piston positions, exact injection adjustment is possible without requiring technically complicated feedback sensors on the adjuster.
