Abstract
A sonic flow-type carburetor having a variable area venturi defined by a conical air nozzle receiving axially within a movable matching conically-shaped plug to define a constricted annular variable area or zone between through which air flows at sonic velocity over a large portion of the operating range of the engine, the plug shape defining a diffuserless nozzle to locate the point of maximum flow velocity at the manifold edge of the plug for better atomization of the fuel and uniform distribution into the air stream for flow into the manifold, the plug having an annular fuel induction port opening into the zone and connected by conduit means to an induction-type fuel supply slot by an overlapping christmas tree-shaped slot, air also being variably supplied to the conduit means as a function of engine operation to vary the fuel induction signal and, therefore, the overall air/fuel ratio of the mixture flow to the engine.
