    • A fuel flow control system for directing fuel within a combustion engine having a plurality of fuel introduction nozzles arranged in a plurality of operationally-distinct groups is disclosed. The system includes a plurality of pumping assemblies each corresponding to one of the nozzle groups. Each pumping assembly includes several fuel motivation elements, each in fluid communication with a fuel supply and a corresponding one of said nozzles. Drive elements, such as variable speed motors, are operatively associated with the pumping assemblies, and direct the motivation elements to transmit fuel to the nozzles. A control assembly independently controls the drive elements, so that fuel flow to each nozzle group is independently controllable. In one embodiment, the motivation elements in each pumping assembly are mechanically linked and operate as discrete groups of elements, thereby delivering uniform fuel flow to each nozzle within a given group of nozzles.
    • 公开了一种燃料流控制系统,用于在内燃机中引导燃料,所述内燃机具有布置在多个操作上不同的组中的多个燃料引入喷嘴。 该系统包括多个泵送组件,每个泵组件对应于一个喷嘴组。 每个泵送组件包括几个燃料激励元件,每个燃料激励元件与燃料供应器和相应的一个所述喷嘴流体连通。 诸如变速马达的驱动元件与泵送组件可操作地相关联,并且引导动力元件将燃料传输到喷嘴。 控制组件独立地控制驱动元件,使得到每个喷嘴组的燃料流是独立可控的。 在一个实施例中,每个泵送组件中的动力元件机械地连接并作为离散的元件组操作,由此在给定的一组喷嘴内向每个喷嘴输送均匀的燃料流。
