Abstract

PURPOSE: To prevent a feed of excessive amount of fuel at a transient time and further prevent a generation of black smoke of an engine, by controlling a fuel feed pump for the fuel injection Diesel engine in the method of opening degree of its throttle valve and rotational speed and the like.
CONSTITUTION: Fuel in a tank 1 is injected to an engine by an oil pump 22 driven by an electric motor 23. A signal of an opening degree sensor 42 of the throttle valve is compensated by PID compensation circuits 53, 54 and input to a minimum signal preference circuit 55 as a voltage signal. A signal of a rotational speed sensor 40 is converted into a voltage signal by a frequency-voltage converter 51 and compared with a reference rotational speed signal in a function generator 52. And the above signal is input to the preference circuit 55 via an integrator 56 to output minimum value. Further to the circuit 55, signals of an exhaust temperature sensor 71 and cooling water temperature sensor 80 are input as a correction signal. Then the output signal is transmitted to the motor 23 via an amplifier 57 to determine its rotational speed.
