ABSTRACT:
A carburetor which is responsive to an operator controlled throttle includes a fuel metering and dispersion system for optimally mixing a fuel with air in preparation for the injection into the intake manifold of an internal combustion engine. The carburetor includes a housing with an air-fuel mixing passageway extending vertically therethrough and a fuel dispersion bar transverse to the air-fuel mixing passageway with a plurality of fuel dispersion openings therein for injecting fuel into the air-fuel mixing passageway transverse to the flow of air. A fuel pressure controlled spool valve in the dispersion bar varies the amount by which the fuel dispersion openings are opened in response to the volume of fuel entering the dispersion bar. Venturi plates upstream of the fuel dispersion bar are pivotally attached for variably opening and closing the air-fuel passageway. Throttle valve means are pivotally mounted in the air-fuel mixing passageway adjacent the fuel dispersion openings for variable opening and closing the space between the fuel dispersion openings and the throttle valves. A metering valve assembly is linked to the venturi plates for variably regulating the flow of fuel from a fuel reservoir into the dispersion bar so that the amount of fuel metered into the dispersion bar increases as the space between the venturi plates increases according to a predefined determined metering criteria.
