Abstract

See full text

The disclosure relates to a cylinder head for covering a combustion chamber of an internal combustion engine. The cylinder head comprises at least one material recess for heat isolation, which is formed in a main body of the cylinder head and is arranged between a fluid-guide channel and a cooling channel. The material recess can be produced e.g. directly during the shaping (e.g. casting or pressing) of the cylinder head and/or thereafter. For example, in the event that exhaust gas is guided through the fluid-guide channel, a significantly lower heat input occurs from the hot exhaust gas into the cooling fluid. In addition, the thermal decoupling via the material recess leads to the hot exhaust gas cooling to a lesser degree in the fluid-guide channel.
