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.
A pump for a combustion engine is disclosed. The pump may have at least one pumping member movable through a plurality of displacement strokes during a single engine cycle. The pump may also have a controller in communication with the at least one pumping member. The controller may have stored in a memory thereof a map relating a speed of the combustion engine and fuel demand to a contribution factor associated with each of the plurality of displacement strokes and a total fuel delivery amount.
