  • Method for local boiling protection of a heat exchanger
    Patent number: 9410505
    Abstract: Various methods and systems are provided for estimating a wall temperature in a heat exchanger and reducing the risk of boiling on a coolant side of the heat exchanger. In one embodiment, a method for an engine comprises estimating a wall temperature at a location in a heat exchanger and adjusting an engine operating parameter of an engine coupled to the heat exchanger based on the wall temperature.
    Type: Grant

  • Methods and systems for exhaust gas recirculation cooler regeneration
    Patent number: 8903632
    Abstract: Various methods and systems are provided for regenerating an exhaust gas recirculation cooler. One example method includes, initiating an EGR cooler regeneration mode, wherein the EGR cooler regeneration mode comprises changing a fuel distribution of a donor cylinder group relative to a non-donor cylinder group of an engine, and increasing at least one of engine speed or load of the engine.
