    摘要： The present invention finds application in fuel injectors having the fluid control passage to the needle valve member coupled to another fluid control passage within the fuel injector. Engineers have learned that decoupling the control passage to the needle valve member with other fluid control passages can allow for greater control of injection events. In addition, by decoupling these fluid passages, it is believed that the fuel injector will perform more like a nominal fuel injector, especially under cold start conditions. Therefore, the present invention utilizes a dual control valve member to independently control fluid flow to the back of the needle valve member and fluid flow to various other components of the fuel injector.

    摘要： A fuel injector for an internal combustion engine comprises a fuel intensification section and a needle control section. The fuel intensification section has an inlet and an outlet. The fuel intensification section receives fuel at a first pressure at the inlet and provides fuel at one of the first and second pressures at the outlet. The second pressure is greater than the first pressure. The needle control section has an injector needle and an injector needle control valve. The injector needle has a first position and a second position. The injector needle is disposed in the second position to allow fuel to flow from the fuel injector to the internal combustion engine. The injector needle control valve controls movement of the injector needle. All of the fuel that flows from the fuel injector to the internal combustion engine passes through the fuel outlet of the fuel intensification section.
