Abstract
A combination fuel introduction, distribution and air shaping device is provided for a fuel carburetion system of an internal combustion engine. The distributor is elongated and of generally inverted tear-drop cross-section. Fuel discharge openings are spaced longitudinally near or at the bottom of the distributor. Spaced-apart teeth aligned with the fuel openings or other means to prevent liquid bridging and depend from the bottom or discharge side of the distributor. The distributor extends across the intake air duct of an air-fuel mixing and modulating device that is adapted to deliver a mixture of finely divided fuel droplets in air to the intake manifold of an internal combustion engine. The body of the distributor divides the intake air flow into two converging air streams which entrain the fuel as liquid droplets sweeping it from the downstream side of the distributor and uniformly distributing the droplets in the air streams.
