ABSTRACT:
A staged carburetor has a body in which a pair of induction passages are formed, an inner passage having a venturi and an outer passage encircling the inner passage. A throttle valve positioned at the outlet of the pair of passages controls the flow of air through the passages. Fuel is delivered to the inner passage through a fuel circuit having an outlet at the venturi. A fuel metering rod extends transversely of the passages and has a variable diameter end portion projecting into the outlet. The metering rod is movable relative to the outlet to vary the quantity of fuel delivered. An air valve positioned in the outer passage normally closes the passage whereby air is initially drawn into the engine only through the inner passage. Increased demand for air by the engine results in opening of the air valve so air is drawn into the engine through both passages. The air valve is linked to the metering rod to move it relative to the outlet as the air valve opens to change the quantity of fuel delivered to the inner passage. The quantity of fuel delivered at any one time mixes with air flowing through the passages at that time to produce an air-fuel mixture whose air-fuel ratio is that necessary for proper operation of the engine.
