Abstract: In a fuel injection pump system for internal combustion engines includes a fuel pump whose pump plunger (14) executes an axially reciprocating and rotating movement, and a switching valve (29) which is controlled by a computerized control device (34) and whose closing period determines the start of delivery and the desired delivery stroke of the pump plunger (14) which effects fuel injection. The desired delivery stroke is calculated by a control computer (35) of the control device (34) according to the instantaneous operating parameters of the internal combustion engine. A stroke transmitter (36) is provided for direction controlling the start of delivery and the end of delivery by means of the pump plunger stroke, the stroke transmitter (36) senses the stroke of the pump plunger (14) and applies it to the control device (34) as an actual delivery stroke signal.
