Cylinder Head Assembly: Description and Operation

Cylinder Head







The cylinder head and camshaft housing have been integrated into a one-piece aluminum cylinder head on the V8 engines. At the same time, the arrangement of the intake port and injector has been optimally designed for direct fuel injection. The water jacket ensures that the cooling system has sufficient reserves even in the cylinder head, which is subject to substantial thermal loads. The one-piece design has also reduced the weight slightly.

The exhaust valves on the naturally aspirated engine are bi-metallic and single valve springs are installed for each valve. The exhaust valves on the turbo engine are also bimetallic and are filled with sodium. Double valve springs are also installed on the outlet side.
