Abstract
The present disclosure is directed to injectors with integrated igniters providing efficient injection, ignition, and complete combustion of various types of fuels. These integrated injectors/igniters can include, for example, multiple drivers used to shape charges, controllers used to modify operations based on ionization parameters, and so on.

25. An injector, comprising:
-
a body having a base portion, a nozzle portion and a channel, wherein the channel is configured to deliver fuel from the base portion to the nozzle portion; an actuator extending through the channel, the actuator having a distal end and a proximal end; a flow valve positioned at the distal end of the actuator; a driver operably connected to the proximal end of the actuator; a first force generator positioned adjacent the driver and configured to impart a force to the driver to move the actuator toward the base portion to close the flow valve; and a second force generator positioned adjacent the driver and configured to impart a force to the driver to influence the actuator and the flow valve. - View Dependent Claims (26, 27, 28, 29, 30, 31)

32. A method for injecting fuel into a combustion chamber of an engine, comprising:
-
determining at least one parameter associated with a combustion event; and transmitting instructions to a force generator to impart a force to a driver to modulate the movement of the valve when the valve is in the open position to influence the fuel dispensed into the combustion chamber. - View Dependent Claims (33, 34, 35, 36, 37, 38)

39. An injector-igniter configured to inject fuel into a combustion chamber of a combustion engine and ignite a fuel air mixture, the injector igniter comprising:
-
a body having a base portion, a middle portion and a nozzle portion; a fuel channel extending from the base portion to the nozzle portion; a flow valve positioned at the nozzle portion and moveable between a closed position and an open position to admit fuel to the combustion chamber; an actuator operably coupled to the flow valve to adjust the position of the flow valve; a driver positioned to engage the actuator to adjust the position of the flow valve; a conductive portion extending from the middle portion to the nozzle portion and configured to deliver electrical energy to ignite the fuel air mixture; and an insulator extending at least partially through the body to the nozzle portion, the insulator defining a gap at the nozzle portion, wherein the gap is configured to facilitate the generation of a plasma. - View Dependent Claims (40, 41, 42, 43, 44)
