INFORMATION ON ENGINE COMPONENTS
1) Injector: introduces pressurised fuel into the com-
GB
bustion chamber.
2)
3)
engine supercharging through the heat exchange with
the water of the sea water circuit.

through the heat exchange with the water of the sea
water circuit.
5) High pressure injection pump: feeds the injectors
with fuel under pressure.
6) Sea water pump: supplies the sea water circuit.
