  • Patent number: 10823045
    Abstract: Methods and systems are provided for a piston. In one example, a system may comprise a plurality of first protrusions and a plurality of second protrusions working in tandem to confine an injection to a radial zone defined by the protrusions.
    Type: Grant
    Filed: November 14, 2018
    Date of Patent: November 3, 2020
    Assignee: Ford Global Technologies, LLC
    Inventors: Eric Kurtz, Nan Robarge, Daniel Kantrow, Christopher Polonowski

  • Patent number: 10487760
    Abstract: A method may comprise: positioning a pressure control valve (PCV) at an outlet of a fuel rail; positioning a volume control valve (VCV) at an inlet of a high pressure pump; and in response to an exhaust particulate matter (PM) level deviating from a target PM level, adjusting a fuel ratio of a first fuel and a second fuel delivered to an engine, and opening one of the PCV and the VCV. In this way, the fuel oxygen content may be adjusted to maintain a PM at or below a target level without a DPF over a broad range of engine designs and operating conditions, while maintaining fuel economy.
