Abstract
An evaporation-cooled internal combustion engine having a cooling system that can be pressurized and that includes a surge tank and a radiator. The surge tank (1) communicates through a line (2) with a section of the cooling system (3) that is constantly full of liquid coolant while the engine is in operation. The engine operation is thereby unaffected by low ambient temperatures.
