The air side of the scavenge air cooler can be
cleaned by injecting a grease dissolving media
through ‘AK’ to a spray pipe arrangement fitted to
the air chamber above the air cooler element.
Drain from water mist catcher
Sludge is drained through ‘AL’ to the drain water
collecting tank and the polluted grease dissolvent
returns from ‘AM’, through a filter, to the chemical
cleaning tank. The cleaning must be carried out
while the engine is at standstill.
The ‘AL’ drain line is, during running, used as a
permanent drain from the air cooler water mist
catcher. The water is led through an orifice to pre-
vent major losses of scavenge air.
The system is equipped with a drain box with a
level switch, indicating any excessive water level.
The piping delivered with and fitted on the engine
is shown in Fig 14.05.01.
Auto Pump Overboard System
It is common practice on board to lead drain wa-
ter directly overboard via a collecting tank. Before
pumping the drain water overboard, it is recom-
mended to measure the oil content. If above
15ppm, the drain water should be lead to the
clean bilge tank / bilge holding tank.
If required by the owner, a system for automatic
disposal of drain water with oil content monitoring
could be built as outlined in Fig. 14.05.02.

The item no refer to ‘Guidance values automation’
