Abstract:
A dual fuel injector may be used to injector both gas and liquid fuel into a cylinder of a compression ignition engine. An injector body defines a first set of nozzle outlets, a second set of nozzle outlets, a first fuel inlet and a second fuel inlet. A dual solenoid actuator includes a first armature, a first coil, a second armature and a second coil that share a common centerline. The dual solenoid actuator has a non-injection configuration at which the first armature is at an un-energized position and the second armature is at an un-energized position. The dual solenoid actuator has a first fuel injection configuration at which the first fuel inlet is fluidly connected to the first set of nozzle outlets, the first armature is at an energized position and the second armature is at the un-energized position. The dual solenoid actuator has a second fuel injection configuration at which the second fuel inlet is fluidly connected to the second set of nozzle outlets, the first armature is at the un-energized position and the second armature is at an energized position. The dual solenoid actuator may also include a combined fuel injection configuration.
