Abstract (en)

The engine has a cylinder head with a cooling system for forming two cooling areas that are running from two coolant flows respectively, where one of the cooling areas is arranged at an outlet duct, and another cooling area is arranged at the remaining of the head. Control units (8) are arranged at the system in such a manner that the coolant flows are separately controllable from each other by the respective cooling areas.
