A fuel injection system is disclosed for use in an internal combustion engine. The system comprises at least one fuel injection valve, a flow sensor responsive to an intake air flow for developing at its output a pulse signal having a frequency corresponding to the intake air flow, and drive means for actuating the fuel injection valve for a predetermined period of time every time a pulse signal is applied thereto from the flow sensor. The amount of fuel to be injected is controlled by the frequency of fuel injection per unit time.
