Exhaust Gas System
The exhaust gas is led from the cylinders to the
exhaust gas receiver where the fluctuating pres-
sures from the cylinders are equalised and from
where the gas is led further on to the turbocharger
at a constant pressure. See fig. 15.01.01.
Compensators are fitted between the exhaust
valve housings and the exhaust gas receiver and
between the receiver and the turbocharger. A pro-
tective grating is placed between the exhaust gas
receiver and the turbocharger. The turbocharger
is fitted with a pickup for monitoring and remote
indication of the turbocharger speed.
The exhaust gas receiver and the exhaust pipes
are provided with insulation, covered by steel
plating.
Turbocharger arrangement and cleaning systems
The turbocharger can either be located on the
aft end of the engine, option: 4 59 121, or on the
exhaust side of the engine, option: 4 59 123. How-
ever, if the engine is fitted with two turbochargers,
they are always located on the exhaust side.
The engine is designed for the installation of the
MAN turbocharger types TCA (4 59 101), ABB
turbocharger type A-L (4 59 102), or MHI turbo-
charger type MET (4 59 103).
All makes of turbochargers are fitted with an ar-
rangement for soft blast cleaning of the turbine
side, and optionally water washing of the com-
pressor side, option: 4 59 145, see Figs. 15.02.02
and 15.02.03. Washing of the turbine side is only
applicable by special request to TC manufacturer
on MAN turbochargers.
