Fig 1 Diagram for combustion air system.
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 tube-type cooler
with a large cooling surface.
The charge air receiver is integrated in the engine
frame on the exhaust side.
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 should be a positive air pressure in
the engine room.
