ABSTRACT:
A fuel injection system for a mixture-compressing spark-ignition internal combustion engine includes an air suction pipe, a throttle valve located in the pipe, and a member upstream of the throttle valve, which is actuatable by air flowing through the suction pipe so as to move a piston valve to dose a quantity of fuel to a fuel injection nozzle. The system includes a duct which bypasses the throttle valve, the duct having a valve which closes the duct when the throttle valve is closed and when the engine is above the idling speed. The duct valve is operatively connected to a switching member which switches off the ignition system of the engine.
