ABSTRACT:
A gaseous carburetor or fuel control system includes a fuel metering assembly, a venturi mixer assembly, a throttle assembly, and an electronic control unit. The control unit controls the fuel metering assembly in a closed loop manner based on detected gas and air pressure to an air/fuel mixing venturi. An electronic governor which controls the throttle valve may also be controlled by the same control unit which controls the fuel metering assembly, using a separate control loop.
