Abstract
A fuel injection equipment including a fuel injector for injecting fuel into a fuel injected space of an internal combustion engine and a fuel pump is disclosed. A generator which is driven by the internal combustion engine and has characteristics of being increased in output voltage or output current with an increase in engine rotation speed is used as any one of an injector driving power supply for feeding the fuel injector with an exciting current through an injector trigger circuit and a fuel pump driving power supply. Use of the generator as the power supply permits the fuel injection equipment to be controlled without requiring a complicated control circuit.
