1.6 Main components of FNM
The main components present on HPE marine engines are listed below.
(1)
Intercooler: Reduces the temperature of the compressed air from the compressor that
flows into the engine intake duct using a bundle of finned tubes crossed by sea water.
(2)
Expansion tank: contains engine coolant.
(3)
Oil sump: contains engine lubrication oil.
(4)
Zinc anodes: prevent the galvanic oxidation of metal parts.
(5)
Oil exchanger: reduces the temperature of the engine lubrication oil.
(6)
Diesel fuel exchanger: reduces the temperature of the fuel in the return line to the
exchanger.
(7)
Air filter: retains the impurities in the air intake.
(8)
Dual heat exchanger (as an alternative to diesel fuel exchanger and in the presence
of steering): reduces the temperature of steering oil and diesel fuel.
(9)
Turbocharger: compresses the intake air exploiting the energy of exhaust gases through
the use of a turbine-compressor group.
(10)
Diesel fuel filter: filters diesel fuel in inlet to the supply line of the engine It can be wall-
