  • Method and system for determining engine knock background noise levels
    Patent number: 11255288
    Abstract: Methods and systems are provided for operating a variable displacement engine that includes a knock control system. Engine knock background noise levels determined during all cylinders operating mode may be determined via two filters that are constructed in parallel. Output of the two filters may be the basis for determining the presence or absence of engine knock.
    Type: Grant
    Filed: May 23, 2018
    Date of Patent: February 22, 2022
    Assignee: Ford Global Technologies, LLC
    Inventors: Mohannad Hakeem, Arney Yogesh Karnik, James Kindree, Christopher Glugla, Robert Baskins
  • Method and system for adjusting engine knock background noise levels
    Patent number: 10975828
    Abstract: Methods and systems are provided for operating a variable displacement engine that includes a knock control system. Engine knock background noise levels determined during all cylinders operating mode may be applied when one or more cylinders are deactivated to determine the presence or absence of engine knock. Additionally, engine knock background noise levels determined during all cylinders operating mode may be applied when one or more cylinders are reactivated such that the engine operates with all cylinder combusting so that the possibility of indicating knock when knock is not present may be avoided.
