A method of producing a cylinder head of an internal combustion engine, comprising a cylinder head housing made of an aluminum material and having a base plate fitted into the combustion-chamber-side base wall of the cylinder head housing and made of a highly heat-resistant material. The combustion chamber plate is connected to the base wall of the cylinder head housing by friction welding.

The invention relates to a tensioning arrangement with a damping device for a belt drive. The tensioning arrangement includes a combination of a pivotal roller lever which supports a tensioning roller, a tension spring engagable with the roller lever and a damping device attached to the roller lever. In order to facilitate a rapid installation and tensioning of the belt on the belt drive, the end of the tension spring opposite the roller lever is connected with a pivotable spring tensioning lever, which spring tensioning lever is selectively movable from a position where the belt is provided with no pretensioning to a pretensioning position where the spring exhibits a predetermined pretensioning force at the belt tensioning roller.
