Abstract
The fuel injection system for an internal combustion engine includes a fuel injection valve for injecting fuel under pressure into an intake pipe of an engine. A vortex flow meter generates a frequency output signal corresponding to the intake air flow rate for the engine and an injection valve drive means for opening the fuel injection valve for a predetermined period is operated in synchronism with the frequency output signal to effect proper fuel injection. A pressure regulating device is provided for holding substantially at a predetermined level the difference between the pressure of the fuel being fed to the fuel injection valve and the pressure in the intake pipe. An electronic control is provided for controlling the difference pressure in accordance with the running state of the engine.
