摘要： Lost motion systems and methods for providing engine valves with variable valve actuation for engine valve events are disclosed. The system may include a master piston hydraulically linked to a slave piston, and a dedicated cam operatively connected to the master piston. The slave piston may be disposed substantially perpendicular to the master piston in a common housing. The slave piston is adapted to actuate one or more engine valves. The slave piston may incorporate an optional valve seating assembly into its upper end. A trigger valve may be operatively connected to the master-slave hydraulic circuit to selectively release and add hydraulic fluid to the circuit.

摘要： An electronic unit injector employs an expandable chamber which expands as pressure in the injector increases between a pair of threshold pressures. The expansion of the chamber results in a two-phase rate of injection of the injector whereby the initial injection rate is significantly lower than the second injection rate. In one embodiment, the expandable chamber is formed by a pin which is displaceable in a cap mounted to the injector body. The pin bottoms against the cap to define the phase transition.

摘要： A lost motion engine valve actuation system and method of actuating an engine valve are disclosed. The system may comprise a valve train element, a pivoting lever, a control piston, and a hydraulic circuit. The pivoting lever may include a first end for contacting the control piston, a second end for transmitting motion to a valve stem and a means for contacting a valve train element. The amount of lost motion provided by the system may be selected by varying the position of the control piston relative to the pivoting lever. Variation of the control piston position may be carried out by placing the control piston in hydraulic communication with a control trigger valve and one or more accumulators. Actuation of the trigger valve releases hydraulic fluid allowing for adjustment of the control piston position. Means for limiting valve seating velocity, filling the hydraulic circuit upon engine start up, and mechanically locking the control piston/lever for a fixed level of valve actuation are also disclosed.

摘要： The present invention provides a hydraulic actuator for operating an engine valve, which includes a means for controlling the seating velocity of the valve. The design allows for free, unrestricted movement of the actuator piston during opening of the engine valve, and an unrestricted return of the piston and valve until the valve is within a predetermined distance of the valve seat. Once within this predetermined range, the return velocity of the actuator piston and engine valve are limited by the rate at which a fluid may escape through a restriction. The restriction is calibrated to provide the desired maximum valve seating velocity. The invention also provides for automatic lash adjustment.

摘要： An injector for a common rail fuel injection system employs a solenoid operated valve configuration which functions to control the amount of filling by regulating the start of filling and the end of filling between the injection events. In some embodiments, a three-way solenoid valve is employed. The start of injection is controlled by a control piston. An intensifier piston is employed to increase the injection pressure. A pilot piston assembly may also be employed to regulate the shape of the injection.

摘要： A fuel injection nozzle and holder assembly of conventional construction is made leakless by eliminating the leakoff passages from the spring chamber. An unreasonable buildup of leakage fuel pressure in the spring chamber is prevented by relieving the pressure in the fuel delivery passages between injection intervals to permit leakage from the spring chamber and a stabilization of the spring pressure. A continuously open passage is provided between the spring chamber and the valve bore to prevent a sealing of the spring chamber by the nozzle valve during the injection interval and thus provide a predictable spring chamber pressure augmenting the nozzle closing force of the spring.
