The aluminium cylinder head has been developed as
a cross-flow cylinder head. A good gas cycle and
therefore a good cylinder charge are achieved as a
result of this.
The cylinder head houses the camshafts, the inlet
camshaft drive and adjustment facility plus the valve
gear with 5-valve technology.
Cylinder head cover
The thin-walled cylinder head cover is manufactured
from a die-cast magnesium alloy.
Sealing between it and the cylinder head is achieved
using rubber gaskets. As a result of this, there is no
direct connection between the cylinder head cover
and the cylinder head, and engine vibrations are not
passed on to the cylinder head cover. The cylinder
head cover is bolted using what are called
decoupling elements.
ELSA provides information on the detailed procedures for preventing cylinder head cover warping and
guaranteeing reliable sealing.
