ABSTRACT:
A staged carburetor comprises a carburetor body having an inner induction passage with a venturi therewithin and an outer induction passage encircling the inner induction passage. A fuel circuit has an outlet at the venturi. A fuel metering rod extends transversely of the induction passages and has a variable diameter end portion projecting into the outlet. The metering rod moves relative to the outlet to vary the quantity of fuel delivered and has an enlarged diameter section intermediate its length which further reduces the cross-sectional area of the inner induction passage at the venturi and increases the pressure drop created thereat. An air valve positioned in the outer induction passage normally closes the passage whereby air is initially drawn into the engine only through the inner induction passage. Increased demand for air results in an opening force being exerted on the air valve to open it so air is drawn into the engine through both induction passages. The air valve is linked to the metering rod to move it relative to the outlet as the air valve opens and change the quantity of fuel drawn into the inner induction passage. Atmospheric air is bled into the inner induction passage to modulate the pressure drop created and control the air-fuel ratio of the mixture produced in the induction passages.
