ABSTRACT:
Liquid fuel from a controlled supply is delivered to a delivery tube under a pressure which is too low to deliver a charge of fuel under static conditions. During an induction stroke however, air entering a cylinder of an engine is drawn through a venturi-type constriction and thereby draws air from a duct by-passing the engine throttle. This air is drawn through a convergent passage to pass the delivery end of the tube at supersonic velocity to draw therefrom a charge of fuel. The tubes for each inlet passage are in permanent communication with the same metered supply so each cylinder draws its appropriate charge in turn.
