ABSTRACT:
In a carburetor for an internal combustion engine, the improvement embodying an air flow surface disposed strategically in a venturi or air flow passageway of the carburetor, the air flow surface providing enhanced air flow velocity characteristics over a region thereof relative to the free stream velocity over the air flow surface, and an orifice located adjacent to the air flow surface in the vicinity of the region of enhanced air flow velocity so as to provide a vacuum signal through the orifice which corresponds substantially proportionally to the air flow velocity through the venturi or air flow passageway, the vacuum signal being usable for improving fuel delivery characteristics to the venturi as well as for other purposes. Several methods for incorporating the present invention into existing carburetor constructions are likewise disclosed.
