  • Enhanced tractive power at low speeds
    Patent number: 9909515
    Abstract: A method is disclosed for operating an internal combustion engine in which a coolant temperature of an engine coolant of the internal combustion engine is determined and is compared with a predetermined threshold temperature. If the coolant temperature is higher than the predetermined threshold temperature, a thermal input into the engine coolant is reduced by changing at least one operating parameter of the internal combustion engine. This can be done, for example, by raising a charging pressure of the internal combustion engine.
    Type: Grant
