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.
Claims18
A method for operating an internal combustion engine, comprising:
- determining a coolant temperature of an engine coolant of the internal combustion engine;
- comparing the coolant temperature with a predetermined threshold temperature;
- and
- reducing a thermal input into the engine coolant by changing at least one operating parameter of the internal combustion engine responsive to a coolant temperature higher than the predetermined threshold temperature.
A motor vehicle with an engine and a controller that is configured to:
- determine a coolant temperature of an engine coolant of the engine;
- and
- reduce a thermal input into the engine coolant by increasing a charging pressure of the engine responsive to a coolant temperature higher than a predetermined threshold temperature.
A method for reducing a thermal input of an engine, comprising:
- increasing a charging pressure of the engine based on a charge air temperature relative to a maximum charge air temperature responsive to a coolant temperature above a predetermined threshold temperature.
