Abstract

An evaporation-cooled internal combustion engine, in which a cooling system, through which a coolant can flow, and to which pressure can be applied, is connected with an equalization container, where the equalization container is connected to a steam-filled zone of the cooling system by means of a connection line. At least one auxiliary means to reduce the interior pressure in the cooling system is assigned to the equalization container.
