Abstract: A fuel injector includes an injector body, and a stack within the injector body, and having a nozzle supply passage therein. The stack includes a solenoid assembly having a solenoid housing piece with a fuel bore formed therein that includes a segment of the nozzle supply passage. The solenoid housing piece includes a solenoid housing material in a base state, and a solenoid housing material in a residual compressive stressed state, with the fuel bore being formed by the solenoid housing material in the residual compressive stressed state. Residual stresses may be imparted by ballizing, nitriding, carburizing, autofrettage, or still another technique.

Abstract: A dual fuel injector may be used to inject 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.

Abstract: An internal combustion engine system is described herein. The system uses a switching rail in combination with a first fuel rail to operate the internal combustion engine of the system. The first fuel rail receives the first fuel for combustion within one or more of the combustion cylinders of the internal combustion engine. The switching rails are configured to receive either the first fuel or a second fuel. A controller is used to operate a switching valve that, depending on the position of the switching valve, routes or directs either the second fuel or the first fuel from their respective fuel tanks. In a switching condition, such as startup, shutdown, or when the second fuel is not available, the controller can use the first fuel as the alternate source of fuel provided through the switching rail.
