摘要： An improved fuel injection system is provided which incorporates a common rail and a plurality of unit injectors which function together to efficiently produce various injection rate shapes and different combinations of discreet and blended pilot, main, post and after treatment fuel injection events during a single injection. The fuel injection system effectively permits flexible, responsively timed, square shaped, discreet low to mid pressure level injections utilizing the fuel pressure of the common rail while also allowing the unit injector portion to function independently to produce flexible and responsively timed and pressure controlled, triangular shaped high pressure fuel injection events and to recover excess energy. In one embodiment, a separate common rail pump is avoided by utilizing the unit injector plunger to replace fuel into the common rail which was previously injected.

摘要： A closed needle injector assembly is provided which effectively permits low fueling quantity control in short duration injections and pilot quantity control in longer duration events without compromising energy efficiency, maximum fuel delivery rates nor requiring increased operating pressures. The closed needle injector assembly includes first and second needle valve elements and a throttle passage formed in the second needle valve element to restrict fuel flow through an injector orifice. The second needle valve element is telescopingly received within the first needle valve element. Respective control volumes and one or more injection control valves are used to control the movement of the needle valve elements. Operation of the assembly results in movement of the first needle valve element to an open position for throttling fuel flow through the throttle passage followed by subsequent lifting of the second needle valve element for longer duration injections.
摘要翻译：提供了一种闭合的针式注射器组件，其在较短持续时间事件中有效地允许短时间注射和先导量控制中的低燃料量控制，而不损害能量效率，最大燃料输送速率，也不需要增加的操作压力。闭合针式注射器组件包括第一和第二针阀元件和形成在第二针阀元件中的节流通道，以限制通过喷射器孔的燃料流。第二针阀元件可伸缩地容纳在第一针阀元件内。各个控制体积和一个或多个喷射控制阀用于控制针阀元件的运动。组件的操作导致第一针阀元件移动到打开位置，用于节流通过节流通道的燃料流动，随后再次提升第二针阀元件以进行更长时间的注射。
