1 -1 Intake and exhaust system
Air introduced from the intake air silencer passes through the
air duct to the air cooler where it is cooled, and is then distrib-
uted to each cylinder via the intake manifold.
Exhaust gas goes from heat exchanger (ftesh water tank),
through the water-cooled turbocharger to the mixing elbow
and is discharged with the sea water.
