Table 1: P2 flange connections are standard according to DIN
86 044. Other flange connections are standard according to DIN
2501.
The air intake to the turbochargers takes place
directly from the engine room through the intake
silencer on the turbocharger.
From the turbocharger the air is led via the charge
air cooler and charge air receiver to the inlet valves
of each cylinder.
The charge air cooler is a compact two-stage tube-
type cooler with a large cooling surface.
The charge air cooler is mounted in the engine's
front end box.
It is recommended to blow ventilation air in the level
of the top of the engine(s) close to the air inlet of the
turbocharger, but not so close that sea water or
vapour may be drawn in. It is further recommended
that there always is a positive air pressure in the
engine room.
Turbocharger
The engine is as standard equipped with a high-effi-
cient MAN Diesel & Turbo TCR turbocharger of the
radial type, which is located on the top of the front
end box.
Cleaning of Turbocharger
The turbocharger is fitted with an arrangement for
dry cleaning of the turbine side, and water washing
of the compressor side.
