  • Method and system for compensating engine blow-through air
    Patent number: 11131261
    Abstract: A method for adjusting an air-fuel ratio of a turbocharged engine that operates without blow though and with blow through is disclosed. In one example, the method provides a way to provide a feed forward fuel adjustment in the presence of engine blow though so that a closed loop controller does not have to exceed its range of control authority.
    Type: Grant
    Filed: November 14, 2019
    Date of Patent: September 28, 2021
    Assignee: Ford Global Technologies, LLC
    Inventors: Douglas Owen Toms, Paul Mahlon Ranspach, Stephen William Magner, Kenneth John Behr, Zena Yanqing Yee

  • Methods and system for catalyst reactivation
    Patent number: 10041424
    Abstract: Embodiments for reactivating a catalyst are provided. In one example, a method for reactivating a catalyst coupled to an engine comprises when the engine is restarted following deactivation, adjusting a degree of fuel enrichment based on an engine off duration and an engine air amount during the restart.

  • Systems and methods for improving engine emissions during starting
    Patent number: 9644559
    Abstract: Systems and methods for improving emissions of an internal combustion engine are presented. In one example, engine crankshaft acceleration is a basis for estimating engine air-fuel ratio during engine starting when output of an oxygen sensor may be unavailable. An actual engine air-fuel ratio may be adjusted in response to the estimated engine air-fuel ratio.
