ABSTRACT:
A cylinder head arrangement of an internal-combustion engine has a three-part housing which comprises a basic housing fitted onto a cylinder block, a bucket tappet housing inserted in the basic housing, and a fitted-on cylinder head cover. The bucket tappet housing is constructed in one piece. The guiding and bearing of engine camshafts takes place in divisible bearing brackets whose upper parts are integrated in the cylinder head cover and whose lower parts are constructed in the basic housing. As a result, a construction of the individual elements is obtained which is easy to manufacture and is largely free of undercuts, the individual elements having a high overall stiffness in the mounted condition and being easy to mount.
