  • Patent number: 12194558
    Abstract: A method is provided comprising identifying an alignment point of a workpiece; positioning a first end of an electrode in the direction of the alignment point of the workpiece; applying a first voltage to the electrode wherein the applied first voltage generates a spark; rotating the electrode in a first direction; advancing the electrode toward the alignment point by a first distance wherein advancing the electrode and applying the first voltage creates a first orifice section; applying a second voltage to the electrode and modifying one or more operational parameters of the electrode; advancing the electrode toward the alignment point by a second distance wherein advancing the electrode and applying the second voltage causes formation of at least a second orifice section; wherein the first and second orifice sections cooperate to form an orifice comprising a first flow area and a second flow area.

  • Patent number: 7080550
    Abstract: A rate tube measurement system for measuring injected fuel and a method thereof are disclosed. In one embodiment, the system includes a fixture assembly, a rate tube fluidically connected to the fixture assembly to receive fuel injected by the fuel injector during, a pressure sensor positioned upstream of the rate tube that is adapted to measure pressure changes in the injected fuel and provide a pressure output, a flow meter that measures flow of injected fuel and provides a flow output indicative of the measured fuel flow, and a computing device that processes the duration of actuation, the pressure output and the flow output to determine injection information such as fuel injection quantity, variation, and rate shape.
