摘要： An improved electronically-controlled fluid injector system comprises a fluid storage chamber and a direct-operated check. Pressurization of fluid in the storage chamber begins before the start of fluid injection. Fluid injection begins by hydraulically unbalancing the check. Fluid injection sharply ends by hydraulically balancing the check to allow a biasing device to close the check. The present invention provides improved control of several fluid injection parameters, including higher peak fluid injection capability and less fluid injection pressure drop at the end of injection, resulting in improved engine performance and lower emissions, noise, and wear.

摘要： A hydraulically actuated fuel injector includes an injector body having a needle control chamber, a nozzle chamber, and a nozzle outlet that opens to the nozzle chamber. Fuel within the injector is hydraulically pressurized during each injection cycle. A needle valve is positioned to reciprocate in the nozzle chamber between an open position in which the nozzle outlet is open and a closed position in which the nozzle outlet is closed. The needle valve includes a closing hydraulic surface exposed to pressure in the needle control chamber. A needle control valve is mounted within the injector body and is moveable between an off position in which the needle control chamber is opened to a source of high pressure fluid and an on position in which the needle control chamber is opened to a low pressure passage.

摘要： A control valve assembly adapted for a fuel injector includes a valve seat with fluid inlet and fluid outlet. A poppet valve controls the flow of fluid through the valve seat. A pair of electrical actuators are selectively operably energized for releasing the poppet and moving the poppet to valve open and closed positions. Split fuel injection can be provided using either sequential operation or concurrent operation, i.e., phasing. Permanent magnets, holding current and residual magnetism enable the latching of the poppet valve in each of the valve open and closed positions.

The control system also has a control chamber located at the base end of the needle check valve, and a control valve movable to selectively drain and fill the control chamber. The control system further has an injector body, a first piston located within the injector body, and a second piston located within the injector body. The first piston is operatively connected to the control valve to move the control valve. The second piston is located a distance from the first piston to form a coupling chamber. The control system additionally has a partial-ball check valve associated with the coupling chamber to selectively replenish the coupling chamber.

摘要： Pressurized injector actuation fluid, such as oil or fuel, is supplied to high pressure common rail by a fixed displacement fluid pump. Variable delivery from the pump is achieved by an improved sleeve metering approach. The sleeve surrounds the reciprocating piston and is manipulated to control venting of pumped fluid through vent ports in the piston. The sleeve is moved by preferably being the armature of a solenoid assembly. The varying of current to the solenoid coil alters the axial position of the sleeve relative to the piston to vary the effective pumping stroke of the piston.

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.
