ABSTRACT:
An electronic fuel supply device for an automotive engine has a vortex flow sensor for sensing the flow of suction air into the engine, an electromagnetic valve which driven for a predetermined time in synchronism with the frequency output from the vortex flow sensor so as to permit the passage of fuel therethrough, and a control valve for limiting the flow of fuel through the electro-magnetic valve. The fuel is metered by the electro-magnetic valve and the control valve, and the fuel may thus be supplied in metered amounts to the fuel injection valves in the respective cylinders for injection into the engine.
