  • Fuel injection pressure pulsation dampening system
    Patent number: 9644590
    Abstract: A fuel injector has a plurality of injection fuel delivery passages, which transport fuel from a proximate end to an injector cavity near the distal end of the fuel injector, wherein less than a total number of injection fuel delivery passages include an orifice. This configuration provides a reduction in fueling variation from pulse to pulse (multi-pulse) with respect to pulse separation due to pressure variation while allowing a sufficient amount of fuel flow to the injector cavity. Thus, the consistency of Start-Of-Injection (SOI) and opening rate both improve significantly and advantageously. For compactness, the orifices may be positioned in a cover plate used to retain the components of the injection control valve assembly and may further be arranged in an arc segment when viewed along a longitudinal axis.

  • SYSTEM AND METHOD FOR DETERMINING INJECTED FUEL QUANTITY BASED ON DRAIN FUEL FLOW
    Publication number: 20140224223
    Abstract: A system and method is provided for controlling the amount of fuel delivered during an injection event by measuring the drain fuel flow from a valve that controls the injection event.
