Abstract: A dual fuel injector utilizes first and second control valves to open and close first and second nozzle outlet sets to inject a first fuel and a second fuel, respectively. The first and second control valves have concentric lines of action, and include a self alignment feature with respect to a flat seat. The two fuels may differ in at least one of chemical identity, matter phase and pressure.

Abstract: A compression ignition dual fuel engine utilizes individual fuel injectors to inject both gaseous and liquid fuels into each engine cylinder. Each of the fuel injectors includes two electrical actuators that control pressure in a respective liquid control chamber and gaseous control chamber to control the opening movement of check valves to facilitate liquid and gaseous fuel injection events, respectfully. The control fluid for liquid injection events is liquid, whereas the control fluid for the gaseous injection event is gaseous. The used liquid fuel drained from each fuel injector is returned for recirculation and subsequent injection, whereas the used gaseous fuel that drains from the fuel injector is supplied to the intake manifold for burning as circumstances permit.
