Patent ID: 8091528

Claim:
An injector for introducing fuel into a combustion chamber and igniting the fuel, the injector comprising: an injector body including— a base portion configured to receive fuel into the body; and a nozzle portion coupled to the base portion, wherein the nozzle portion is configured to be positioned proximate to the combustion chamber for injecting fuel into the combustion chamber; an ignition feature at the nozzle portion and configured to generate an ignition event to at least partially ignite fuel; a valve carried by the body, wherein the valve is movable to an open position to introduce fuel into the combustion chamber; and a force generator assembly carried by the base portion, the force generator assembly including— a valve driver carried by the base portion, wherein the valve driver is movable between a first position and a second position; and a force generator carried by the base portion and configured to actuate the valve driver, the force generator including— a first solenoid winding configured to generate a magnetic field, wherein the magnetic field moves the valve driver from the first position to the second position to move the valve to the open position; and a second solenoid winding separate from the first solenoid winding, wherein the second solenoid winding is electrically coupled to the ignition feature, wherein the magnetic field generates ignition energy in the second solenoid, and wherein the second solenoid supplies the ignition energy to the ignition feature to at least partially initiate the ignition event.
