    摘要： A closed nozzle fuel injector is provided which effectively controls the fuel injection flow rate, especially during an initial portion of an injection event, while also permitting accurate control over pilot and/or post injection flow rates at all operating conditions thereby advantageously reducing emissions and combustion noise. The injector includes a rate shaping orifice to restrict fuel flow during an initial portion of an injection event and a rate shaping sleeve mounted for movement to cause a greater flow of injection fuel during a later portion of the injection event. A damping chamber and orifice are also provided to control movement of the rate shaping sleeve.

    摘要： An improved fuel injector is provided which effectively controls fuel injection events using two injection control valves which operate in series to control the movement of a nozzle valve element. An outer injection control valve and actuator assembly operates to control fluid pressure in a control volume adjacent an inner injection control valve thereby controlling the movement of the inner control valve which, in turn, controls fuel pressure in an inner control volume adjacent one end of the nozzle valve element. A particular design of the inner injection control valve prevents control valve oscillations thereby minimizing unwanted fuel injection variations.
