Abstract

A cylinder head for an internal combustion engine has at least two cylinders, each cylinder having an outlet opening for discharging the exhaust gases out of the cylinder, an assembly end side for connection to a cylinder block of the engine, an exhaust-gas line adjoining each outlet opening, the exhaust-gas lines of the at least two cylinders merging within the cylinder head to form a combined exhaust-gas line, and a coolant jacket interior to and at least partially integrated in the cylinder head, the coolant jacket made up of a lower coolant jacket and an upper coolant jacket, and at least one connection between the lower coolant jacket and the upper coolant jacket immediately adjacent the combined exhaust-gas line for allowing the passage of coolant.
