摘要： A fuel injector includes a homogenous charge nozzle outlet set and a conventional nozzle outlet set that are controlled respectively by first and second three way needle control valves. Each fuel injector includes first and second concentric needle valve members. One of the needle valve members moves to an open position for a homogenous charge injection event, while the other needle valve member moves to an open position for a conventional injection event. The fuel injector has the ability to operate in a homogenous charge mode with a homogenous charge spray pattern, a conventional mode with a conventional spray pattern or a mixed mode.

摘要： Engineers have determined that the ability to front end rate shape injection events can result in a number of advantages, including improved injector performance and a reduction in undesirable emissions. In addition, engineers have learned that it is desirable for the needle valve to open slowly at the beginning of an injection event and to close abruptly to end the injection event. Therefore, the present invention utilizes at least one orifice member that is movably positioned in an injector body such that fluid flowing away from the needle valve member closing hydraulic surface flows through a relatively restricted flow path and fluid flowing toward the needle valve member flow through a relatively unrestricted flow path.

摘要： The present invention relates to engines having multiple hydraulic devices. For instance a multi-cylinder diesel engine might include both an a fuel injector and an engine compression release brake. Traditionally, each of these hydraulic devices has been controlled by an individual actuator control valve. However, engineers have learned that decreasing the number of engine components can increase engine robustness. In addition, engineers have learned that de-coupling fluid pressure to the needle valve member hydraulic surface from fluid pressure lines to other injector components can result in greater control of the injector. Therefore, the present invention utilizes a single actuator control valve to control both hydraulic devices for an engine cylinder and to provide independent control of fluid pressure to the needle valve member closing hydraulic surface.
摘要翻译：本发明涉及具有多个液压装置的发动机。例如，多缸柴油发动机可以包括燃料喷射器和发动机压缩释放制动器。传统上，这些液压装置中的每一个都由单独的致动器控制阀控制。然而，工程师们了解到，减少发动机部件数量可以提高发动机的鲁棒性。此外，工程师们已经了解到，从流体压力管线将针阀构件液压表面的流体压力解耦到其它喷射器部件可以更好地控制喷射器。因此，本发明使用单个致动器控制阀来控制用于发动机气缸的两个液压装置，并且提供对针阀构件关闭液压表面的流体压力的独立控制。

摘要： The present invention relates to high speed control valves which are especially applicable for use in fuel injection systems. Producing a valve with a quick response time within acceptable packaging constraints and with a structure that allows the valve to be mass produced with consistent performance between valves is extremely problematic. By moving flow restrictions within the valve away from the valve seats, flow forces on the valve member can be reduced, while possibly also permitting a reduction in the necessary travel distance of the valve member to improve response time and other performance characteristics. The valve is particularly applicable in controlling hydraulic pressure applied to the closing hydraulic surface of a direct control needle valve in a fuel injector.
摘要翻译：本发明涉及特别适用于燃料喷射系统的高速控制阀。在可接受的包装限制内产生具有快速响应时间的阀门，并且具有允许阀门在阀门之间具有一致性能的批量生产的结构是非常有问题的。通过将阀内的流动限制移动离开阀座，可以减小阀构件上的流动力，同时还可以减小阀构件的必要的行进距离以改善响应时间和其他性能特征。该阀特别适用于控制施加到燃料喷射器中的直接控制针阀的关闭液压表面的液压。

摘要： A variable discharge pump is provided, the pump comprising a pumping chamber and a reciprocating plunger disposed within a plunger bore so as to reciprocate within the pumping chamber. The pump also has an electrically actuated spill control valve which opens or closes fluid communication between the pumping chamber and a low pressure area. The control valve is operated for a first period of time extending from a first time point occurring after the plunger passes bottom dead center to a second time point occurring before the plunger passes top dead center. The control valve is then operated for a second period of time extending from a third time point occurring between the second time point and the passing of the plunger through top dead center to a fourth time point occurring after the plunger has passed top dead center.
