  • Controls for break-in operation of green engines
    Patent number: 11781498
    Abstract: An electronic control system configured to control operation of an engine by evaluating whether to operate the engine in a green engine break-in mode. In the green engine break-in mode, the electronic control system is configured to determine a break-in torque limit for the engine, dynamically vary the break-in torque limit in response to break-in operation of the engine, and control operation of the engine using dynamically modified break-in torque limit.

  • ENGINE CONTROLS FOR EXHAUST AFTERTREATMENT THERMAL MANAGEMENT
    Publication number: 20220356851
    Abstract: A method includes operating an engine system including a plurality of cylinders, a plurality of fuel injectors configured to provide fuel the plurality of cylinders, a compression braking system configured to selectably brake at least a first set of the plurality of cylinders, and an exhaust aftertreatment system including at least one catalyst. The method includes determining a condition for brake-fuel operation and, in response to the act of determining, operating the engine in a brake-fuel mode wherein the compression brake is actuated to provide compression braking of the first set of the plurality of cylinders and a second set of the plurality of cylinders receives and combust fuel provided from respective ones of the plurality of fuel injectors.
