ABSTRACT:
A ceramic body for use as a gas conduction channel or duct and preferably used to define an exhaust channel in a cylinder head of an internal combustion engine, where the cylinder head is cast around the ceramic body. The ceramic body is provided with a thickening or external layer over at least a part of its outer surface. This external layer adds stability and strength to the ceramic body and allows it to withstand the pressures occurring during the casting of the cylinder head. The thickening or external layer is formed from a pressure resistant material and may be applied to a depression in the ceramic body or into the space between two parallel ceramic bodies to provide the required strength and stability.
