Abstract

PURPOSE: To save electric power for a driving motor, by supplying a current to the driving motor of a fuel pump in response to the engine load.
CONSTITUTION: A switching transistor 11 is connected to a motor 2 and a power supply 5 in series, a control circuit 12 generates on-off control signal of the switching transistor 11 in response to the output signal of a fuel controller 9, and a Zener diode B is connected to the motot 2 in parallel. Because conduction of the switching transistor 11 is chopper-controlled by the output signal Ti of a fuel injection valve controller 9, the driving power of the motor 2 is controlled in response to the amount of fuel supplying i.e. the engine load so that the driving power is small if the engine load is low and the driving power increases as the engine load rises high.
