ABSTRACT:
An electronic fuel injection system is combined with a carburetor in a carbureted internal combustion engine. The resulting air/fuel induction system comprises a carburetor air/fuel induction system in combination with an electronic fuel injection system which uses the carburetor of the carburetor system as the air valve for the electronic fuel injection system. The carburetor system and the electronic fuel injection systems are interconnected, preferably so that the mixture cut-off of the carburetor system is employed to shut off fuel flow in the carburetor to the air stream for the induction manifold and to simultaneously turn on the electronic fuel injector system. Either manual or automatic interconnection can be employed in the present invention.
