摘要

Apparatus for metering the quantity of air supplied to at least one fuel system in a carburetor for an internal combustion engine. The carburetor has at least one air passageway therein through which air is drawn into the engine. Fuel is supplied to the carburetor through the fuel system and mixed with air as it passes through the carburetor and the carburetor has a conduit through which air is introduced into the fuel system. The apparatus comprises a chamber having an air inlet in communication with the air passageway of the carburetor and a plurality of air outlets in communication with the conduit. An electrically operated valve selectively opens and closes each air outlet and electrical current is selectively supplied to each valve whereby one or more of the air outlets may be opened thereby to supply air from the passageway to the conduit and to control the quantity of air flowing to the fuel system.
