Abstract: A fuel injection pump for combustion engines with at least one pump piston which is actuated by a cam mounted on a mechanically operable camshaft is disclosed. The piston stroke is utilized only in part for delivery of the fuel, whereby the fuel feed volume is controllable by changing the effective piston stroke. The fuel injection pump also includes a control element which, in conformity with the number of revolutions of the combustion engine, varies the first derivative of the function of the effective piston stroke in accordance with the cam angle.

Abstract: A fuel injection pump control for internal combustion engines including a pump piston which pump piston is actuatable by a shaft and a cam follower roller adapted to contact the pertaining cam of the camshaft, whereby the fuel delivery volume can be adjusted by varying the effective delivery stroke. The shaft is pivotally connected to the pump piston; the longitudinal central axis of the pump piston is arranged in the plane of rotation of the cam and eccentrically to the camshaft axis; and, coaxial to the axis of rotation of the cam follower roller and/or at the end of the shaft, there is connected to the shaft a rocking lever the free end of which is adjustable within a predetermined area, preferably a triangular area.
