A clamping flange on the cylinder head allows easy
removal and installation of the module with
a minimum of bolting.
The terminal block does not have to be detached.
The exhaust manifold is designed as a split
manifold. A divider is integrated in the manifold to
ensure a steady flow of exhaust gases onto the
turbine wheel. The ports of cylinders 1 and 4 and
cylinders 2 and 3 are separated according to the
firing order. Furthermore, the divider prevents the
exhaust gas pressure from expanding into ports of
the other cylinders.
This allows the required turbine speed to be
maintained and optimises turbocharger response.
