摘要： A mechanically actuated electronically controlled fuel injector (MEUI) includes a first electrical actuator that controls the position of a spill valve, and a second electrical actuator to control pressure on a closing hydraulic surface associated with a directly operated needle valve. The fuel injector is actuated via rotation of a cam to move a plunger to displace fuel from a fuel pumping chamber either to a spill passage, or at high pressure out of a nozzle outlet of the fuel injector for an injection event. The minimum controllable fuel injection quantity, especially as it relates to small closely coupled post injections following a large main injection, is accomplished by the inclusion of a variable flow rate valve that restricts fluid flow from a needle control chamber toward a drain, but is relatively unrestricted to high pressure fluid flow toward the needle control chamber. The inclusion of the variable flow rate valve slows the rate at which pressure drops in the needle control chamber to commence an injection event, but permits a fast rate at which pressure may build in the needle control chamber to end an injection event. The result is a smaller post injection quantity and more controllability over the dwell time between injection events.

摘要： A mechanically actuated electronically controlled fuel injector includes a first electrical actuator that controls the position of a spill value, and a second electrical actuator to control pressure on a closing hydraulic surface associated with a nozzle check valve. The fuel injector is actuated via rotation of a cam to move a plunger to displace fuel from a fuel pressurization chamber either to a spill passage or at high pressure out of a nozzle outlet of the fuel injector for an injection event. Pressure in the fuel injector is moderated when the plunger is moving and the nozzle check valve is in a closed position by briefly cracking open the spill valve to relieve some pressure during the dwell between injection events, such as between a large main injection event and a small close coupled post injection event. This strategy allows for longer dwell times between injection events as well as smaller injection quantities in the post-injection.

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.
