摘要： The injection system comprises a pump designed to send fuel at high pressure to an accumulation volume, for example formed by a common rail, for supplying a plurality of injectors. The pump comprises at least one pumping element actuated with reciprocating motion with a compression stroke at a sinusoidal speed, in synchronism with each step of fuel injection. The injection system comprises at least one by-pass solenoid valve, which is controlled by a chopper control unit for modulating the delivery of the pumping element by varying both the instant of start and the instant of end of delivery during the compression stroke, in such a way that the delivery is synchronous with the injection phase.

摘要： Fuel injection apparatus often uses valves which rapidly move in a start and stop motion for the purpose of starting and stopping injection. Undesirable inertial forces result from such start-stop movement of the valves. To limit such undesirable forces, a pair of valves (72,92) are provided for continuous rotation for starting and stopping injection.

摘要： A fuel injector includes an injector housing having a plunger assembly disposed within a central axial bore and including a lower plunger, an intermediate plunger, and an upper plunger. The lower plunger reciprocates within the central bore to meter a variable quantity of fuel and to inject this fuel during downward portions of the reciprocating motion. A timing chamber formed between the upper and intermediate plungers receives an amount of timing fluid to create a variable length hydraulic link between the plungers. The fluid is drained from the chamber through a drain passage at the end of the injection cycle. The timing chamber has associated with it a mechanism for changing the effective flow function of the drain passage, at a point in the cycle following fuel injection, to maintain a large downward pressure on the lower plunger to hold the lower plunger down and thus prevent additional, undesired fuel flow into the combustion chamber. In a preferred embodiment, the drain passage is located along the central axis of the intermediate plunger, and the upper plunger is provided with a projecting portion which moves into position as the timing chamber collapses to effectively constrict the drain passage, thus changing the timing fluid flow function to a function which provides greater fluid pressure in the timing chamber.

摘要： A piezoelectric flow control valve comprising a slidable closure member (22) for controlling a flow of fluid through a fluid passage (42) between a fluid inlet (40) and a fluid outlet (32). The closure member (22) is biased toward a normally closed position by a plunger (70) responsive to a hydraulic pressure in a pressure chamber (78) which is in fluid communication with the fluid inlet (40) through a restriction and with a pumping chamber (96) of a piezoelectric pump (72). In order to prevent fluid leakage under situations wherein the fluid pressure at the fluid inlet (40) is not high enough to ensure closure of the member (22), the present invention provides spring biased pressure mechanism (106) for biasing the closure member (22) toward the normally closed position and override means (130) for overriding the pressure mechanism (106) in response to a predetermined pressure at the fluid inlet (40).

摘要： A controller, in electrical communication with the one or more of the injectors and a high-pressure fuel pump, generates a first signal responsive to which the valve in the injector opens or closes and a second signal responsive to which the high-pressure fuel pump increases or decreases the pressure level in the fuel accumulator. The system may also include one or more sensors to detect a pressure within the air manifold and to detect the pressure within the fuel accumulator. The controller is programmed to calculate an in-cylinder gas pressure. When the engine is operating at a maximum engine load and the in-cylinder gas pressure reaches or exceeds a maximum pressure limit, the controller transmits one or more signals to adjust the fuel injection timing and/or adjust the pressure in the fuel accumulator to maintain NOx and fuel consumption within acceptable limits.
