ABSTRACT:
A variable Venturi carburetor having a Venturi portion defined by movable members which are linked with and driven by an accelerating pedal so as to vary the area of its throat opening in accordance with a required engine output power thereby establishing air flow through the Venturi throat at the acoustic speed for the most part of the engine operational region. In high load operation wherein the acoustic speed is not maintained at the Venturi throat, fuel pressure is modified to compensate therefor.
