Abstract
An engine comprises a cylinder head connected to a cylinder block; a cooling circuit including a pump, a heat exchanger, and a ventilation vessel; a liquid-cooled component, connected into the cooling circuit by a connecting line and arranged between the pump and the ventilation vessel, which is cooled when the engine is not in operation; and a valve which is self-controlling as a function of coolant pressure arranged in the connecting line between the pump and the ventilation vessel, the valve adjustable between a first working position having a first, relatively small cross section of the connecting line, and a second working position, having a second, relatively large cross section of the connecting line, the valve controlling coolant throughput, wherein when the engine is not in operation and coolant pressure is reduced, the valve is in the second working position to provide an enlarged flow cross section.
