Highly accurate continuous-flow vaporized fuel supply for large dynamic power ranges

A method of controlling a fuel supply to an internal combustion (IC) engine, comprising:

• controlling a flow rate of a fuel supply using a flow control assembly, the flow control assembly comprising:
• a valve body including a fuel flow inlet, a fuel flow outlet, and an orifice coupling fuel flow inlet and outlet,
• a valve member including a shaft and a flow control surface positioned on a first end of the shaft and configured to engage the orifice to control the flowrate of the fuel supply,
• a linear motion actuator coupled with a second end of the shaft and configured to move the valve member axially relative to the orifice, and
• a controller configured to control the linear motion actuator;
• receiving, by the controller, a fuel flowrate command from a commanding controller, wherein the fuel flowrate command is a supersonic value;
• and
• controlling, by the controller, the actuator to move the flow control surface to a position to provide for the fuel supply to be discharged from the flow valve assembly at a flowrate corresponding to the fuel flowrate command.
