Fuel introduction device for internal combustion engine

Claim 1

In combination with an air-liquid fuel induction device that includes an intake air duct having a converging portion, a variable area throat portion of rectangular cross-section through which a mixture of air and finely divided liquid fuel is passed at sonic velocity and a fuel supply, a fuel dispensing and air flow shaping device including in combination: a. an elongated distributor body positioned upstream of the throat and extending within said air duct in a direction parallel to the longer axis of the rectangular throat, said distributor body being positioned at an intermediate location within said air duct to divide the flow of air into converging streams; b. means forming a plurality of displaced fuel openings in said distributor body extending longitudinally therealong, said openings being located within the converging portion of the intake air duct and adapted to discharge fuel therefrom in a plurality of coherent liquid streams for atomization by the converging air streams; c. means forming an internal passage within said distributor body and connected to said fuel supply communicating with the openings for the passage of liquid fuel; d. fuel joinder prevention means attached to said distributor body positioned downstream of said openings and spaced therefrom, said fuel joinder prevention means being spaced along substantially the entire length of said body transversely of the direction of air flow and being effective to minimize joinder between streams of liquid fuel discharged from said openings, and e. the distributor body having an exterior surface portion extending between the fuel openings and the joinder prevention means providing an uninterrupted surface over which fuel flows under conditions of relatively low air velocity moving past said openings.
