The cylinder head is of special significance in a combustion engine. The way it is constructed has a considerable influence on the operating behaviour and performance of the engine.
the cylinder head has the following tasks:
* to seal off the combustion chamber from the cylinder block.
* to determine the shape of the combustion chamber and to dissipate the heat from the combustion.
N air-cooled engines, the heat from the combustion is dissipated through the integrated cooling fins, and in water-cooled engines it is dissipate ted through the water ducts.
The cylinder head controls the charge changing process in the engine, provides the fresh gas feed and discharges the exhaust gases. Furthermore, it accommodates the valves. In engines with overhead camshafts, it accommodates the valve train together with the camshaft. In engines with camshafts underneath, it accommodates only parts of the valve train.
