Abstract
A power device for driving an auxiliary equipment for an internal combustion engine capable of driving both a fuel injection unit and a valve without specifically providing a adjusting valve when the engine includes no battery acting as a power supply. A generator driven by the internal combustion engine is provided therein with a generating coil for driving the auxiliary equipment which is common to both a pump motor and an actuator. A driving power feed circuit is arranged for feeding driving power to the pump motor and actuator from the generating coil for driving the auxiliary equipment which acts as a power supply. The driving power feed circuit includes a pump driving switch for switching a driving current of the pump motor, an actuator driving switch for switching a driving current of the actuator, and a switch control unit for turning on the pump driving switch and actuator driving switch at duty ratios different from each other, respectively.
