ABSTRACT:
A flow regulating carburetor having a movable control element operating within the throat of a venturi air passage, the element being automatically displaced to vary the effective size of the throat as a function of the mass-volume of the air stream flowing through the passage. This produces a velocity-pressure differential acting automatically to regulate the quantity of fuel induced through a fuel tube communicating with the throat and intermingling with the air stream to provide a ratio of air-to-fuel representing the optimum value for the prevailing condition of engine speed and load throughout the entire engine operating range, thereby effecting a marked improvement in fuel economy and reducing the emission of pollutants.
