Fuel injector-igniters with variable gap electrodes. A fuel injector-igniter comprises a housing, an actuator disposed in the housing, and a valve including a valve head operative to open and close against a valve seat in response to activation of the actuator. An electrode cage surrounds the valve head and includes at least one aperture. At least one reed electrode extends from the electrode cage to form a gap between the reed electrode and the housing. The valve head includes a magnet, such as a permanent magnet, wherein the magnet is operative to move the reed electrode toward the electrode cage when the valve head opens, thereby increasing the gap.

1. A fuel injector-igniter, comprising: a housing;an actuator disposed in the housing;a valve including a valve head operative to open and close against a valve seat in response to activation of the actuator; andat least one movable electrode attached to the vale head and forming a variable gap between the electrode and a portion of the housing;wherein the electrode is positioned to move relative to the valve head in response to a fuel flow past the valve head, thereby varying the gap. 2. The fuel injector-igniter according to claim 1, wherein the movable electrode extends from the valve head. 3. The fuel injector-igniter according to claim 1, wherein the at least one moveable electrode is pivotably attached to the valve head. 4. The fuel injector-igniter according to claim 1, wherein the at least one moveable electrode comprises a flexible reed electrode. 5. The fuel injector-igniter according to claim 4, wherein the flexible reed electrode deflects in response to fuel flow past the valve head. 6. A fuel injector-igniter, comprising: a housing;an actuator disposed in the housing;a valve including a valve head operative to open and close against a valve seat in response to activation of the actuator, wherein the valve head includes a magnet;an electrode cage surrounding the valve head and including at least one aperture; andat least one reed electrode extending from the electrode cage to form a gap between the reed electrode and housing;wherein the magnet is operative to move the at least one reed electrode toward the electrode cage when the valve head opens, thereby increasing the gap. 7. The fuel injector-igniter according to claim 6, wherein a proximal end portion of the reed electrode is attached to the electrode cage. 8. The fuel injector-igniter according to claim 7, wherein a distal end portion of the reed electrode is biased toward the housing. 9. The fuel injector-igniter according to claim 8, wherein the reed electrode comprises spring steel. 10. The fuel injector-igniter according to claim 7, wherein the at least one reed electrode is positioned over the at least one aperture and operative to cover the at least one aperture during a combustion event. 11. The fuel injector-igniter according to claim 6, wherein the reed electrode is pivotably supported on the electrode cage. 12. The fuel injector-igniter according to claim 6, wherein the magnet is a permanent magnet. 13. A fuel injector-igniter, comprising: a housing;an actuator disposed in the housing;a valve including a valve head operative to open and close against a valve seat in response to activation of the actuator, wherein the valve head includes a magnet;an electrode cage surrounding the valve head and including a plurality of apertures; anda plurality of reed electrodes, each extending from the electrode cage to form a gap between the reed electrode and housing, wherein each reed electrode is positioned over a corresponding aperture and operative to cover the aperture during a combustion event;wherein the magnet is operative to move the reed electrodes toward the electrode cage when the valve head opens, thereby increasing the gaps. 14. The fuel injector-igniter according to claim 13, wherein a proximal end portion of each of the reed electrodes is attached to the electrode cage. 15. The fuel injector-igniter according to claim 14, wherein a distal end portion of each of the reed electrodes is biased toward the housing. 16. The fuel injector-igniter according to claim 15, wherein the reed electrodes comprise spring steel. 17. The fuel injector-igniter according to claim 13, wherein each reed electrode is pivotably supported on the electrode cage. 18. The fuel injector-igniter according to claim 13, wherein the magnet is a permanent magnet. 19. The fuel injector-igniter according to claim 13, wherein the reed electrodes comprise a ferromagnetic material. 20. A fuel injector-igniter, comprising: a housing;an actuator disposed in the housing;a valve including a valve head operative to open and close against a valve seat in response to activation of the actuator; andat least one flexible reed electrode extending from the valve head to form a gap between the reed electrode and the housing;wherein fuel flow past the valve head at least partially flows through the gap and is operative to deflect the reed electrode, thereby increasing the gap. 21. The fuel injector-igniter according to claim 20, wherein the reed electrode is attached to the valve head. 22. The fuel injector-igniter according to claim 20, further comprising a plurality of flexible reed electrodes attached to the valve head. 23. The fuel injector-igniter according to claim 20, wherein a distal end portion of the reed electrode is biased toward the housing. 24. The fuel injector-igniter according to claim 23, wherein the reed electrode comprises spring steel. 25. The fuel injector-igniter according to claim 20, wherein the reed electrodes comprise a ferromagnetic material.
