Abstract

A cylinder head of an internal-combustion engine is disclosed which includes a horizontally divided carrier in which camshaft bearings as well as receiving devices for bucket tappets are arranged. The arrangement is constructed rigidly as a result of longitudinal and transverse webs and, by removing the receiving devices from the cylinder housing, permits the use of a simple casting method for the cylinder head housing.
