Main Components Of Fnm ® Engine, Hpe Series - FNM HPE Series Owner's Manual

1.6 Main components of FNM
The main components present on HPE marine engines are listed below.
(1) Intercooler (except HPEL45): 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 (except HPEL45): 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-
mounted in the engine compartment.
