Injector-igniter with thermochemical regeneration

摘要

A fuel injection system comprising an injector-igniter and a fuel tank in fluid communication with the injector-igniter. The injector igniter includes an injector housing and a valve assembly. The valve assembly includes a valve and a valve seat electrode located within the injector housing. The valve seat electrode forms an annular spark gap between the electrode and an electrode portion of the injector housing. An actuator, such as a piezoelectric actuator, is disposed in the housing and connected to the valve. In some embodiments, the system further comprises a thermochemical reactor operatively coupled to the injector-igniter to provide a supplemental supply of hydrogen for combustion enhancement. In other embodiments, a hydraulic stroke amplifier is disposed between the actuator and valve.
