Fuel injector and method
Abstract:
Embodiments may provide a fuel injector including a nozzle body having one or more nozzles, each capable of spraying a fuel from a respective spray position, and movable to change the spray position from a first position to a second position. An injector needle may be configured for axial movement relative to the nozzle body from an engaged position, to prevent flow through the one or more nozzles, to a disengaged position. The movement of the one or more nozzles from the first position to the second position and then back to the first position may substantially correspond with, and/or may be substantially be determined by, the relative axial movement between the injector needle and the nozzle body from the engaged position to the disengaged position and then back to the engaged position.
