In a process for controlling the beginning of delivery of a fuel injection pump for internal combustion engines having fuel injection, particularly Diesel engines, in dependence on the torque and under consideration of immediately measurable operation parameters, at least the revolution speed. The torque is determined from the intake boost pressure generated by a turbocharger and optionally from that amount of air which is blown off at increasing revolution speed above a certain intake boost pressure. A device for performing said process comprises a processor for performing at least one calculating operation provided with a store for storing the program to be executed, sensors transmitting signals to the processor representative of operation parameters of the injection-type internal combustion engine, and actuating means for controlling the beginning of fuel delivery of the fuel injection pump being connected with the processor. For determining the torque delivered by the engine there is provided a sensor for the intake boost pressure and a further sensor designed as pressure transducer for the differential pressure at a restriction for supplying to the processor a value corresponding to the air blown off.
