  • Methods and system for determining engine air-fuel ratio imbalance
    Patent number: 11125176
    Abstract: Systems and methods for operating an engine that includes an oxygen sensor and one or more fuel injectors for each engine cylinder are described. In one example, lines describing a relationship between a fuel mass multiplier and a coefficient of a function describing output of an oxygen sensor to a step change in fuel mass are a basis for determining air-fuel imbalance of engine cylinders.
    Type: Grant

    Date of Patent: September 21, 2021
    Assignee: Ford Global Technologies, LLC
    Inventors: Michael Kluzner, Robert Jentz, Kenneth John Behr, Christopher Weber, Andrew Bagnasco

  • Determining degradation of an idle air throttling device
    Patent number: 6945222
    Abstract: A method to determine degradation of an idle air throttling device in an internal combustion engine. Degradation is determined in a manner that may permit evaluation of both the idle air throttling device and expected engine operating conditions.

  • Fiber optic misfire, knock and LPP detector for internal combustion engines
    Patent number: 5763769
    Abstract: A fiber optic spark plug integrated combustion pressure detector comprises the sensitive sensor head with "snap" action diaphragm to provide the temperature insensitivity to combustion temperature variations. The optical module is integrated into the electrical connector to eliminate open optical interfaces. The "snap" action and special diaphragm shape selectively increase detector knock and misfire discrimination. The pressure sensor can be made spark plug integrated or injected in block cylinder for combustion pressure sensing in engine.
