Abstract: Method for operating a power plant for generating energy, comprising at least one stationary internal combustion engine (1) and a district heating system (20) connected to the at least one internal combustion engine (1) in a heat exchange relationship, wherein the at least one internal combustion engine (1) is configured to deliver a mechanical power by burning a fuel, wherein on the one hand the at least one internal combustion engine (1) is cooled and on the other hand heat is supplied to the district heating system (20) through a heat exchange between the district heating system (20) and the at least one internal combustion engine (1) and wherein at least one additional cooling device (12) is provided, wherein the cooling of the at least one internal combustion engine (1) is effected—at least partially—using the at least one additional cooling device (12) when a transient performance requirement for the at least one internal combustion engine (1) occurs.

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.
