ABSTRACT:
A fuel injection pump for internal combustion engines has a pump piston, defining a pump work chamber for generating an injection pressure; an electromagnetic control device for fixing the duration of supply during the supply stroke of the pump piston and a measuring device, which measures the return flow fuel quantity that did not attain injection during the supply stroke of the pump piston and emits an electronic return flow quantity signal (Q.sub.R). An electronic control unit imposes control signals (.phi..sub..mu.V) upon the control device as a function of the return flow quantity signal (Q.sub.R) and operating characteristics of the engine. To attain highly accurate closed-loop control of the fuel injection quantity, a fluctuation detector is provided, which detects fluctuations in the return flow quantity signal and emits the appearance of fluctuations over time in the form of detection signals (.phi..sub.A, .phi..sub.E, .phi..sub.1 -.phi..sub.4). The control unit corrects the imposition of the control signals (.phi..sub..mu.V) as a based on these detection signals.
