摘要： A fuel injector for use in an internal combustion engine includes a valve member that is moveable within a bore of an injection nozzle so as to be engageable with a valve seat region to control fuel delivery through one or more nozzle outlets, an injector body housing an actuator that is operable to move the valve member within the bore, and defining an accumulator volume for storing high pressure fuel. The fuel injector includes a damping chamber in fluid communication with the accumulator volume through a fluid passage, the damping chamber serving to reduce pressure wave activity within the accumulator volume.

摘要： The present invention relates to a fuel injector for use in delivering fuel to an internal combustion engine. The fuel injector includes a nozzle having a valve needle which is movable with respect to a valve needle seat. The valve needle travels through a range of movement between a closed position and an open position to control fuel delivery through at least one nozzle outlet. The valve needle cooperates with a needle sleeve or a control member which is located in a piston guide. The valve needle is movable relative to the needle sleeve or the control member. The needle sleeve or the control member is movable relative to the piston guide. The invention also relates to a method of operating a fuel injector; and a fuel injector control unit.
