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.
Claims20
A cylinder head of a multi-cylinder internal-combustion engine having a divided carrier for receiving camshafts which act upon valves by way of bucket tappets, the carrier having bearings for the camshafts constructed to be detachable from the cylinder head housing and having longitudinal webs extending in the direction of the crankshaft in parallel to one another and at a distance from one another and having transverse webs extending at a right angle with respect to the longitudinal webs, wherein the longitudinal webs include struts forming receiving devices for the bucket tappets and bridges connecting these receiving devices.
A method of making a cylinder head of a multi-cylinder internal combustion engine of the type having a divided carrier for receiving camshafts which act upon valves by way of bucket tappets, the carrier having bearings for the camshafts constructed to be detachable from the cylinder head housing and having transverse webs extending at a right angle with respect to longitudinal webs,
- said method including forming the carrier with struts extending as the longitudinal webs, said method further including forming the struts so as to constitute receiving devices for the bucket tappets and bridges connecting these receiving devices.
