Abstract
The present invention provides a fuel injector comprising a nozzle body within which first and second valve needles are slidable. The first valve needle is engagable with a first seating to control fuel injection from a first outlet opening provided in the nozzle body and the second valve needle is engagable with a second seating to control fuel injection from a second outlet opening provided in the nozzle body. The fuel injector further comprises first and second control chambers for fuel, whereby fuel pressure within the first and second control chambers controls movement of the first and second valve needles away from their respective seatings so as to permit fuel delivery from a selected outlet opening. The first and second valve needles being arranged adjacent to one another.
