Abstract

A cylinder head for a valve-controlled internal combustion engine with a cylinder head housing, in which there are bearing blocks for the inlet or outlet camshaft. At least one camshaft has a camshaft adjuster, by way of which the position of the drive wheel of the camshaft can be changed relative to the axis of rotation of the camshaft. At least the bearing block, which is provided next to the camshaft adjuster and is intended for the camshaft, exhibits a segment, whose width is reduced owing to a recess for the screw connection of the cylinder head housing. The bearing site, arranged next to the camshaft adjuster, provides a bearing sleeve for the camshaft, in such a manner that the segment of the bearing block that is provided with a reduced bearing block width is expanded to the actual bearing block width. The sleeve exhibits openings to supply oil for the camshaft adjuster. Force-fed oil can be fed to the camshaft adjuster by way of the bearing sleeve over the bearing block, which is arranged next to the camshaft adjuster, despite the bearing block's recesses, which reduce its bearing width.
