Steve William Magner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Two-stage catalyst regeneration
    Patent number: 10221792
    Abstract: A system and method are described for reducing NOx emissions following deceleration fuel shut off (DFSO). The method comprises: cutting off fuel to the engine during a deceleration event; open loop operating the engine air/fuel ratio rich of stoichiometry for a predetermined time after the deceleration event; feedback controlling the air/fuel ratio on average near a value rich of stoichiometry for a preselected time after said predetermined time; and feedback controlling the air/fuel ratio returning to stoichiometry after the preselected time.
    Type: Grant
    Filed: August 15, 2013
    Date of Patent: March 5, 2019
    Assignee: Ford Global Technologies, LLC
    Inventors: Mario Santillo, Mrdjan J. Jankovic, Steve William Magner, Michael James Uhrich
  • Method for identification of a threshold-level catalyst
    Patent number: 9359967
    Abstract: Systems and methods for estimating catalyst transfer function gain are disclosed. In one example, an air-fuel ratio forcing function is applied to a catalyst. Air-fuel ratios upstream and downstream of the catalyst are manipulated to determine a transfer function gain of the catalyst. The transfer function gain may be a basis for indicating the presence or absence of catalyst degradation.
