Abstract
A fuel injector for an internal combustion engine comprising an injection nozzle comprising a nozzle body with a nozzle bore; a valve needle assembly received within the nozzle bore and including a valve needle engageable with a seat region to control fuel delivery through an outlet of the injection nozzle; and a first actuator arrangement operable to apply an opening force to an engagement region of the valve needle assembly to cause an opening movement thereof. The first actuator arrangement comprises a first conductive coil mounted concentrically on a first body and a first armature configured to apply the opening force to the valve needle assembly. The first body comprises a first, radially inner region having a relatively high magnetic permeability and a second region having a relatively low magnetic permeability, the second region being disposed radially between the first coil and the first, radially inner region.
