Abstract
Provided is an internal combustion engine, comprising at least one cooling device for cooling at least one operational liquid of the internal combustion engine during and/or after operation of the internal combustion engine. The at least one cooling device has at least one heat exchanger and lines for transporting the at least one operational liquid to and from the at least one heat exchanger. The heat exchanger exchanges heat with a cooling medium, which cooling medium has during the operation of the internal combustion engine a lower temperature than the at least one operational liquid of the internal combustion engine. Heat is exchanged by the heat exchanger between the at least one operational liquid and the cooling medium, which cooling medium has before and/or during a starting operation of the internal combustion engine a higher temperature than the at least one operational liquid of the internal combustion engine.
