An ultrasonic apparatus and a method for injecting a pressurized liquid fuel by applying ultrasonic energy to a portion of the pressurized liquid fuel. The apparatus includes a die housing which defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The die housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of a die tip. The exit orifice is adapted to receive the pressurized liquid from the chamber and pass the liquid out of the die housing. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip. The method involves supplying a pressurized liquid to the foregoing apparatus, applying ultrasonic energy to the pressurized liquid but not the die tip while the exit orifice receives pressurized liquid from the chamber, and passing the pressurized liquid out of the exit orifice in the die tip.

1. 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.
