    摘要: A parasitic load control system is provided. The system may include an exhaust producing engine and a fuel pumping mechanism configured to pressurize fuel in a pressure chamber. The system may also include an injection valve configured to cause fuel pressure to build within the pressure chamber when in a first position and allow injection of fuel from the pressure chamber into one or more combustion chambers of the engine when in a second position. The system may further include a controller configured to independently regulate the pressure in the pressure chamber and the injection of fuel into the one or more combustion chambers, to increase a load on the fuel pumping mechanism, increasing parasitic load on the engine, thereby increasing a temperature of the exhaust produced by the engine.

    摘要: A fuel injector includes first and second check valve members that open and close first and second nozzle outlet sets, respectively, to inject two fuels that differ in at least one of chemical identity, pressure and molecular state. The first check valve member defines a through passage, includes a closing hydraulic surface exposed to fluid pressure in the first control chamber, and moves into and out of contact with a first seat on an injector body. The second check valve member includes a closing hydraulic surface exposed to fluid pressure in a second control chamber, and moves into and out of contact with a second seat located on the first check valve member. A control valve member is movable between first and second positions that respectively block and allow fluid communication between the first and second control chambers and a drain outlet.

    摘要: A dual fuel common rail engine supplies pressurized natural gas and liquid diesel fuel at different pressures through a co-axial quill assembly for direct injection from a single fuel injector into an engine cylinder. Each coaxial quill assembly includes a matched pair of inner and outer quills that are chosen to have dimensions that allow both quills to sealingly engage each fuel injector at a common conical seat responsive to a clamping force applied along an axis. Matched pairs of inner and outer quills are retained together during pre-installation handling with a retainer that is left between the inner and outer quills after installation in an engine.

    摘要: An electronically controlled fuel injector includes a reduced part count and complexity over similar fuel injectors without a substantial reduction in performance capabilities. This is accomplished by using a one-piece needle that is hydraulically balanced and biased toward a closed position with a spring positioned in the needle control chamber. Although subtle, this injector has some ability to control the fuel pressure when the needle valve is opening and closing by adjusting a relative timing of a pressure control valve opening relative to a needle control chamber, using separate electrical actuators. The invention is particularly applicable to fuel injectors that cycle through high and low pressure states during and between injection events, respectively. Cam actuated fuel injectors being particularly well suited.

    摘要: A common rail single fluid fuel injection system includes fuel injectors with a single electrical actuator but the ability to produce ramp, square and split injection rate shapes. This is accomplished by including a control valve member that is operably coupled to the electrical actuator and is movable between a high pressure seat and a low pressure seat. A fuel supply passage is opened to a nozzle passage by moving an admission valve member from a closed position to an open position by relieving fuel pressure on a control surface via movement of the control valve member. In addition, a needle valve member is movable from a closed position to an open position by relieving pressure on a closing hydraulic surface associated with the needle valve, which is again accomplished via movement of the control valve member via the electrical actuator.

    摘要: A valve comprises a valve body that includes an upper valve seat and a bore wall that defines a bore. A seat component is at least partially positioned in the bore and includes a lower valve seat. The seat component is radially out of contact with the bore wall. The upper valve seat and the lower valve seat are concentrically coupled via a valve member which is movable between the upper valve seat and the lower valve seat. The valve finds preferred application as a needle control valve in a fuel injector.

    摘要: A control valve, preferably for use in a fuel injector, includes a valve body defining an inlet passage separated from an outlet passage by a valve seat. A single pole solenoid is attached to the valve body, and includes a pole piece and an armature. A valve member with a centerline is positioned in the valve body, attached to the armature and moveable between an open position in which the inlet passage is open to the outlet passage, and a closed position in which the inlet passage is closed to the outlet passage. The pole piece is positioned between the valve seat and the armature along the centerline of the valve member.
