  • 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.
    Type: Grant
    Filed: May 24, 2022
    Date of Patent: October 10, 2023
    Assignee: Cummins Inc.

  • Patent number: 8904769
    Abstract: An internal combustion engine system includes: an engine with a plurality of pistons housed in respective ones of a plurality of cylinders; an air intake system to provide air to the plurality of cylinders through respective ones of a plurality of intake valves; an exhaust system to release exhaust gas from the plurality of cylinders through respective one of a plurality of exhaust valves; an aftertreatment system to treat exhaust emission from the engine; at least one sensor to provide a sensor signal corresponding to an efficiency of the aftertreatment system; and a controller coupled to the at least one sensor and operable to regulate an internal exhaust gas recirculation operation in the cylinders when the aftertreatment system operates at less than a desired efficiency.
