  • Method for determining regeneration parameter values of a multiple LNT catalyst system, and device for data processing
    Patent number: 11352926
    Abstract: Methods and systems are provided for adjusting a regeneration scheme in response to ageing of a first catalyst and a second catalyst. In one example, a method may include determining a first ageing of the first catalyst and a second ageing of the second catalyst and updating factors of the regeneration scheme based on the first ageing and the second ageing.
    Type: Grant
    Filed: January 15, 2020
    Date of Patent: June 7, 2022
    Assignee: Ford Global Technologies, LLC
    Inventors: Frank Linzen, Christoph Boerensen, Jan Harmsen, Christian Nederlof, Dirk Roemer
  • Methods and systems for an exhaust gas treatment arrangement
    Patent number: 10746115
    Abstract: Methods and systems are provided for an exhaust aftertreatment arrangement. In one example, a system includes a LNT upstream of an SCR with an oxygen storage component arranged therebetween, and where a rich operation of an engine is limited based on an oxygen load of the oxygen storage component when an exhaust gas temperature is higher than a limit temperature.

  • Methods and systems for an exhaust gas treatment arrangement
    Patent number: 10563556
    Abstract: Methods and systems are provided for an exhaust gas arrangement. In one example, a system includes a lean-NOx trap arranged upstream of a selective-catalytic reduction device with an air supply device positioned to inject air therebetween, wherein the air supply device is activated in response to an exhaust gas being rich and an exhaust gas temperature exceeding a limit temperature.
