摘要： A fuel injector includes first and second electrical actuators positioned within an injector body. First and second pairs of electrical conductors extend from a socket connector outside of the injector body to the first and second electrical actuators, respectively. The electrical conductors extend through an elastomeric sealing member that seals against fuel leakage from the fuel injector. The elastomeric sealing member provides annular sealing ridges in sealing contact with an access passage of the injector body and includes individual conductor seal passages that form seals around the outer surface of the individual electrical conductors. The elastomeric sealing member includes features that facilitate assembly of the fuel injector in a manner that reduces risk of damage to the sealing strategy.

摘要： A fuel system includes a plurality of fuel injectors each defining a nozzle supply passage, a nozzle outlet and a low pressure space. The fuel system includes a plurality of mechanically actuated pressure intensifiers each including a tappet and being positioned partially within one of the fuel injectors, and a common rail fluidly connecting with each of the fuel injectors. Each of the fuel injectors further includes an injection pressure control mechanism having an injection pressure control valve. Each injection pressure control valve blocks the corresponding pressure intensifier from the common rail and fluidly connects the pressure intensifier with the low pressure space at a first position, and fluidly connects the pressure intensifier with the common rail and blocks the pressure intensifier from the low pressure space at a second position. Injecting fuel via operating the fuel system may include operating the fuel system in a low leakage mode where the pressure intensifier displaces fuel at a low pressure, between high pressure injections.

摘要： A fuel injector includes an auxiliary valve member that can assist in raising a mean injection pressure, increase a nozzle valve opening pressure, and hasten the closure rate of a nozzle valve member over an equivalent fuel injector without the auxiliary valve. The auxiliary valve member is fluidly positioned between a needle control chamber and a high pressure space, which includes a fuel pressurization chamber within the fuel injector. The auxiliary valve member includes a closing hydraulic surface exposed to fluid pressure in the high pressure space. The plumbing and the auxiliary valve member allow high pressure fuel to act upon a closing hydraulic surface of the nozzle valve member to increase valve opening pressure and mean injection pressure. The needle control chamber may be vented or may be a closed volume when the auxiliary valve member is in its closed position. The invention is potentially applicable to any fuel injector, but finds the preferred application in cam actuated fuel injectors that include an electronically controlled spill valve.

摘要： The present invention relates to fuel injectors having a free floating plunger. Traditional tappet assemblies include a plunger that is mechanically coupled to the tappet, and therefore, cannot be uncoupled over a portion of its movement during an injection event. In the event of a plunger seizure in a traditional tappet assembly, the tappet spring can be prevented from expanding, which can cause major valve train and engine damage. In addition, because the plunger in traditional tappet assemblies is moved to its upward position under the action of the tappet spring, the fuel passages can depressurize if fuel cannot refill the fuel pressurization chamber as quickly as the plunger retracts, causing cavitation bubbles. Therefore, the present invention utilizes a plunger that is not mechanically coupled to the tappet and can uncouple from the tappet during the injection event to address these and other problems related to plunger wear and failure.
摘要翻译：本发明涉及具有自由浮动柱塞的燃料喷射器。传统的挺杆组件包括机械联接到挺杆的柱塞，因此在喷射事件期间不能将其移动到其一部分运动上。在传统挺杆组件中发生柱塞塞住的情况下，可以防止挺杆弹簧膨胀，这可能导致主要的阀门系列和发动机损坏。此外，由于传统挺杆组件中的柱塞在挺杆弹簧的作用下移动到其向上的位置，所以如果燃料不能像柱塞缩回那样快速地重新填充燃料加压室，则燃料通道可以减压，导致气泡。因此，本发明利用一种柱塞，其不与挺杆机械联接，并且可以在喷射事件期间与推杆脱离，以解决与柱塞磨损和故障相关的这些和其它问题。
