Abstract:
An ultrasonic fuel injector apparatus for injection of liquid fuel into an internal combustion engine, the apparatus comprising:a die housing defining: a chamber adapted to receive a pressurized liquid fuel; an inlet adapted to supply the chamber with the pressurized liquid fuel; and a die tip, the walls of the die tip defining at least one vestibular portion terminating in at least one exit orifice, the vestibular portion being adapted to receive the pressurized liquid fuel from the chamber and pass the liquid fuel to the exit orifice and out of the die housing: and a means for applying ultrasonic energy to a portion of the pressurized liquid fuel without vibrating the die tip, the means for applying ultrasonic energy is affixed at a nodal point to the die housing and terminates in a distal end wherein the means for applying ultrasonic energy is located in close proximity to the vestibular portion and the distal end comprises a cross-sectional area equal to the opening of the vestibular portion.
