ABSTRACT:
The invention is based on a fuel injection pump in which an adjuster, which may also be an injection onset adjuster, is actuated via an adjusting mechanism, and 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, making a graduated, geometrically defined adjustment of the adjusting piston possible, but no feedback sensors for the actual status of the adjusting mechanism at a given time are required.
