Abstract
In a cylinder head of a multicylinder internal combustion engine comprising a casting having a bottom wall, a top wall and outer side walls delimiting together a cooling water space through which intake and exhaust passages extend to the side walls, cylinder head bolt-receiving tubular columns extend from the top walls toward the bottom walls only to a certain distance from the bottom wall and are joined to the side walls and transverse walls for uniformly transmitting bolting forces from the bolt receiving tubular columns to the bottom wall.
