摘要： A fuel system includes a plurality of fuel injectors fluidly connected to a common rail. Each of the fuel injectors has at least one body component and includes an intensifier control valve for controlling movement of an intensifier piston, a needle control valve for controlling movement of a needle valve member, and exactly one electrical actuator coupled with the intensifier control valve and the needle control valve via a coupling linkage. The intensifier control valve and the needle control valve each include a valve member that is movable with respect to a valve seat. The electrical actuator includes an intermediate position during which the valve member of one of the intensifier control valve and the needle control valve is in contact with the respective valve seat, and the valve member of the other of the intensifier control valve and the needle control valve is out of contact with the respective valve seat.
