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 turbochargers are located on the exhaust
side of the engine.
The engine is designed for the installation of the
MAN turbocharger type TCA, option: 4 59 101,
ABB turbocharger type A-L, option: 4 59 102, or

rangement for water washing of the compressor
