  • Cylinder exhaust gas recirculation distribution measurement systems and methods
    Patent number: 10590872
    Abstract: Methods and systems are provided for measuring exhaust gas recirculation (EGR) distribution among individual engine cylinders. In one example, a method may include fluidly coupling a plurality of intake runners of an engine to a vacuum pump, diverting a portion of intake charge gas from the intake runner to a gas composition sensor with the vacuum pump, measuring an oxygen concentration of the diverted intake charge portion with the gas composition sensor, and estimating an EGR concentration of the intake charge based on the measured oxygen concentration.
    Type: Grant

    Date of Patent: March 17, 2020
    Assignee: Ford Global Technologies, LLC
    Inventors: Tyler Lacey, Shawn Spannbauer, Norman Opolsky, Chad Stateler

  • Exhaust leakage management
    Patent number: 9103271
    Abstract: Embodiments may provide an exhaust gas management arrangement for an engine. The exhaust gas management arrangement may include a port disposed to capture an exhaust gas leaked from a movable portion of an exhaust gas flow directing mechanism. The arrangement may also include a passage to direct the leaked exhaust gas to a crankcase of the engine.
