Patents by Inventor Eric James Kastanis

Eric James Kastanis 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).

  • Diesel engine particulate filter regeneration system and methods
    Patent number: 11156178
    Abstract: Methods and systems for supplying post injection fuel to a two stroke diesel engine are described. In one example, post injection fuel timing is adjusted responsive to an amount of internal residual combustion products in a cylinder so that less post injected fuel may be trapped in the cylinder for a subsequent cycle of the cylinder. The start of post injection fuel timing and the amount of post injection fuel may be adjusted responsive to internal residual in the cylinder.
    Type: Grant
    Filed: September 12, 2017
    Date of Patent: October 26, 2021
    Assignee: Ford Global Technologies, LLC

  • Diesel engine particulate filter regeneration system and methods
    Patent number: 10508607
    Abstract: Methods and systems for estimating an amount of residual or retained fuel that remains in a cylinder from a first cycle of the cylinder to a second cycle of the cylinder are described. In one example, the amount of residual fuel is estimated in response to a temperature of an oxidation catalyst. The retained fuel amount may then be the basis for adjusting fuel injection amounts during the second cycle of the cylinder.

  • Method for operating an engine
    Patent number: 10502152
    Abstract: Methods and systems for operating an engine during and after regeneration of a particulate filter are described. In one example, exhaust flow is increased and exhaust temperature is decreased in response to ceasing regeneration of a particulate filter so that SCR efficiency may be improved in a short amount of time.
