A cylinder head is composed of a basic housing resting on a cylinder block, said housing having gas exchange channels and valves, a bearing housing supporting camshafts and cup tappets, and a cylinder head cover. This cover is made integral with the upper parts of the camshaft bearings. The arrangement has a single separating plane, at which both the basic housing with elevated outside walls and the bearing housing and the cylinder head cover abut. This arrangement has high rigidity and is easy to assemble.

Cylinder head arrangement of an internal-combustion engine

A camshaft for an internal combustion engine which is arranged in bearings that are formed by a cylinder head and a camshaft bearing housing. The camshaft is secured either at the cylinder head or at the camshaft bearing housing by means of holders, i.e., it represents together with one of the two housings of the internal combustion engine a preassembled structural unit. As a result thereof, the assembly of the camshaft becomes more simple.
