ABSTRACT:
In a fuel injection system which electrically controls an amount of pressurized fuel supplied to an internal combustion engine, an electromagnetic valve which opens to inject the pressurized fuel is disposed at an upstream of a throttle valve in an intake pipe so that a group of cylinders of the engine is supplied with fuel therefrom. A pressure regulator is provided to regulate a pressure of the pressurized fuel in proportion to an intake pressure present at a downstream of the throttle valve.
