摘要： The present invention relates to a fuel injector (1) for use in delivering fuel to an internal combustion engine. The fuel injector (1) includes a nozzle having at least one nozzle outlet. A valve needle is moveable with respect to a valve needle seating through a range of movement between a closed position and an open position to control fuel delivery through the at least one nozzle outlet. The movement of the nozzle needle is controlled by fuel pressure within a control chamber (18). The injector (1) has first and second nozzle control valves (8, 10) for controlling fuel flow into and out of the control chamber (18) to pressurise and depressurise the control chamber, respectively. The first nozzle control valve (10) can operate selectively to place the control chamber (18) in fluid communication with a fuel drain (28). The first nozzle control valve (8) can also operate selectively to place the control chamber (18) in fluid communication with a high pressure supply line (26). The second nozzle control valve (10) can operate selectively to place the control chamber (18) in fluid communication with a fuel drain (30). In an alternate arrangement, a filling valve (80) can be provided selectively to place a high pressure supply line (24) in fluid communication with the control chamber (18). The present invention also relates to a method of operating a fuel injector (1); and a fuel injector control system.
