Beschreibung
Zusammenfassung:	A fuel injector for delivering fuel to an engine in which a housing of the injector has an internal fuel chamber and at least one exhaust port in fluid communication with the fuel chamber. A control system operates the fuel injector to direct fuel within the fuel chamber of the housing to be exhausted from the housing through the at least one exhaust port. At least a portion of an elongate ultrasonic waveguide separate from the housing extends longitudinally within the fuel chamber of the housing and has a terminal end proximate to the at least one exhaust port. Said portion of the waveguide is tubular and defines an interior passage of said portion. Said tubular portion of the waveguide is open at its terminal end to permit fuel in the fuel chamber to flow within the interior passage of said tubular portion of the waveguide. An excitation device is operable to ultrasonically excite said ultrasonic waveguide.
