Abstract
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 whereby fuel exits the fuel injector at the at least one exhaust port for delivery to the engine. An ultrasonic waveguide is separate from the housing, and is elongate and disposed at least in part within the fuel chamber to ultrasonically energize fuel within the fuel chamber prior to the fuel exiting through the at least one exhaust port. An excitation device is operable to ultrasonically excite the ultrasonic waveguide. A mounting member interconnects the waveguide to the housing, with the mounting member configured to substantially vibrationally isolate the housing from the waveguide.
