  • System and methods for starting an engine
    Patent number: 11098688
    Abstract: Systems and methods for operating a vehicle that includes an engine that may be automatically stopped and started are described. In one example, an amount of time to start an engine and a rate of engine acceleration are adjusted in response to what type of event triggered an automatic engine start.
    Type: Grant
    Filed: August 26, 2019
    Date of Patent: August 24, 2021
    Assignee: Ford Global Technologies, LLC

  • Method and system for regenerating a gasoline particulate filter
    Patent number: 10598069
    Abstract: Methods and systems are presented for regenerating a particulate filter. In one example, vehicle speed control mode parameters may be adjusted in response to an amount of soot stored in a particulate filter being greater than a first threshold. The vehicle speed control parameters may be returned to base values in response to the amount of soot stored in the particulate filter being less than a second threshold.

  • System and method for cold start control of internal combustion engines
    Patent number: 6491024
    Abstract: Systems and methods for controlling an internal combustion engine during and shortly after starting include controlling combustion burn location via ignition timing to improve engine stability while reducing feedgas emissions. Open or closed loop control based on observed or measured mass fraction burned or cumulative released heat allows maintenance of a lean air/fuel ratio charge with significantly retarded ignition timing to reduce catalyst light-off time and temperature and reduce engine feedgas emissions.
