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： Controlling fuel injectors to create varying injection rates and injection rate shapes typically involves using multiple control valves to control fuel pressure and check valve opening pressure independently. The fuel injector of this application uses a single control valve positioned between a fuel supply passage and a tip supply passage. The control valve has at least three positions. In a second position allowing a first maximum fuel injection rate and allowing a second maximum fuel injection rate in a third position.

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： 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.
