Abstract
The cylinder head arrangement of an internal-combustion engine has a basic housing, a support component and a cylinder head cover. The three housing components are assembled such that two independent junction planes are formed. In both of these junction planes, grooves are placed in at least one of the two adjoining housing components and serve as oil ducts and form the mutually independent oil galleries or oil supply branches. These independent oil supply ducts supply different consuming devices with oil. Bores are largely eliminated and a course of the oil ducts which is free of intersections is provided also for very complex cylinder head arrangement having a large number of consuming devices.
