Abstract

PURPOSE: To prevent a fuel feed of excessive amount to an engine at its transient operation and further prevent a generation of black smoke, by controlling a fuel pump of the Diesel engine of fuel injection type on the basis of its throttle valve opening degree, rotational speed, intake negative pressure, etc.
CONSTITUTION: Fuel in a tank 1 is injection fed to an engine by a pump 4 driven by an electric motor 5. The signal of a throttle valve opening degree sensor 41 is corrected by PID compensation circuits 24, 25, to which an actual measurement signal is input from a motor speed detecting circuit 30, and input to a minimum signal preference circuit 26. The signal of a rotational speed sensor 21 is input to a function generator 27 via a frequency-voltage converter 23 and compared with a reference speed signal. While the signal of a suction pressure sensor 41 is output through an amplifier 42 and upper limit circuit 43. The above both signals are arithmetically processed by an integrator 28. Then the minimum value is output by the circuit 26 and transmitted to the motor 5 through an amplifier 29.
