Exhaust system

Basic construction elements
Danger:
The exhaust system must be completely
gastight in order to fully exclude the
danger of poisoning.
Under no circumstances may water be allowed to
ingress the engine via the exhaust gas system. In
the case of a low installation of the engine and
exhaust gas outlet, just above or below the water
line, a bend must be built into the pipe, with a
subsequent falling exhaust gas outlet ("swan neck
layout")
À . This is to prevent water ingressing the
engine when manoeuvring astern.
Caution:
If sea water ingresses the engine, it will
result in a total write−off that is not covered
by the MAN warranty.
It is not permissible to provide a single common
exhaust system for several engines. In the case if
multi−engine layouts a separate exhaust system for
each engine is obligatory, so that with one engine
running, no exhaust gas can enter the other
engine/s.
Securing exhaust system
Caution:
Secure and support the exhaust pipes so
that no forces act on the turbochargers.
How the exhaust system is secured depends on its
basic design.
If the exhaust system is connected to the engine
by way of heat−resistant hoses, the supports can
be attached to the engine and gearbox feet
(
Á and  ).
If the exhaust system is connected to the engine
by way of bellow expansion joints, the exhaust
system must be suspended from vertically
adjustable brackets
