摘要： In dual fuel engines, it is desirable to have injection of two distinct quantities of liquid fuel. Engines with these operating requirements have typically used two separate fuel injectors, or two separate nozzle assemblies, to satisfy this need. However, these systems can be rather complex and difficult to control. In addition, engineers have learned that fuel injectors having direct control have better performance which can increase engine efficiency. Therefore, the present invention addresses the needs of engines desiring injection of two distinct quantities of fuel, such as dual fuel engines, by utilizing a direct control fuel injector having a dual concentric check having separate orifices for the pilot and main injections.

摘要： A control valve, preferably for use with a fuel injector, includes a valve body defining a solenoid cavity, an inlet passage, an outlet passage and a metering passage extending between the solenoid cavity and the outlet passage. A solenoid is mounted in the solenoid cavity. A valve member has one end attached to the solenoid and is positioned to reciprocate in the valve body between an open position in which the inlet passage is opened to the outlet passage and a closed position in which the inlet passage is closed to the outlet passage. The inlet passage is in fluid communication with the solenoid cavity via the metering passage when the valve member is in its open position. Appropriate sizing of the metering passage can prevent secondary injections by providing adequate pressure relief to the solenoid cavity while also substantially damping any pressure waves that may travel to the solenoid cavity through the metering passage.

One of the first valve body component and the second valve body component define an inlet passage opening to the high pressure cavity. A valve member has a portion positioned in the high pressure cavity and is moveable between a closed position in which the valve member contacts the valve seat closing the outlet passage to the high pressure cavity, and an open position in which the outlet passage is open to the high pressure cavity. The sealing land has a symmetrical non-circular shape.

摘要： A cartridge control valve includes a valve body that defines an inlet passage separated from an outlet passage by a flat valve seat. A solenoid is attached to the valve body. A valve member has one end positioned in the valve body and an other end attached to the solenoid. The valve member has an annular knife edge valve surface located between the one end and the other end. The valve member is moveable from a first position to a second position by energizing the solenoid. The annular knife edge surface is away from the flat valve seat to open the inlet passage to the outlet passage when the valve member is in one of its first position and its second position. The annular knife edge valve surface is seated against the flat valve seat to close the inlet passage to the outlet passage when the valve member is in the other of its first position and its second position.

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.
