Scavenge Air System
Scavenge air is supplied to the engine by one or
more turbochargers, located on the exhaust side
of the engine.
The compressor of the turbocharger draws air
from the engine room, through an air filter, and
the compressed air is cooled by the scavenge
air cooler, one per turbocharger. The scavenge
air cooler is provided with a water mist catcher,
which prevents condensate water from being car-
ried with the air into the scavenge air receiver and
to the combustion chamber.
The scavenge air system (see Figs. 14.01.01 and
14.02.01) is an integrated part of the main engine.
The engine power figures and the data in the list
of capacities are based on MCR at tropical con-
ditions, i.e. a seawater temperature of 32 °C, or
freshwater temperature of 36 °C, and an ambient
air inlet temperature of 45 °C.
