Cylinder head for an internal combustion engine

An internal combustion engine with a cylinder head having at least two cylinders, each cylinder having at least two outlet openings for discharging exhaust gases out of the cylinder, the cylinder head comprising:

• an assembly end side for connection to a cylinder block of the engine,
• an exhaust-gas line adjoining each of the at least two outlet openings of each cylinder, the exhaust-gas lines of the at least two outlet openings of each cylinder firstly merging to form a partial exhaust-gas line which is associated with the cylinder,
• the partial exhaust-gas lines of the at least two cylinders merging within the cylinder to form a combined exhaust-gas line,
• a coolant jacket interior to and at least partially integrated in the cylinder head, the coolant jacket comprising a lower coolant jacket arranged between the exhaust-gas lines and the assembly end-side of the cylinder, and an upper coolant jacket arranged on that side of the exhaust-gas lines which is situated opposite the lower coolant jacket, and only two connections between the lower coolant jacket and the upper coolant jacket immediately adjacent the combined exhaust-gas tines-line and located in an outer wall of the cylinder head, said two connections allowing for passage of coolant;
• and
• at least one cylinder-side connection between the lower coolant jacket and the upper coolant jacket provided between the partial exhaust-gas lines of two adjacent cylinders of the at least two cylinders—at a distance from said partial exhaust-gas lines.

An engine cylinder head, comprising:

• multiple partial exhaust-gas lines merging into a combined exhaust-gas line,
• a lower coolant jacket adjacent to the partial exhaust-gas lines,
• an upper coolant jacket arranged on an exhaust-gas line side opposite the lower coolant jacket, and
• only two connections between the lower and upper coolant jackets in an outer wall of the cylinder head, said two connections immediately adjacent to and on each side of the combined exhaust-gas line.
