Engine Elements - FNM HPE Series Installation Manual

Figure 2- Lifting bar for engine levelling.
Consult the length of the lifting bar in the following table:
Model

1.9HPE
2.4HPE
3.0HPE
See the position of the hooks in paragraph 3.3 - Engine
elements on 8.
In the case of engines with the inverter connected,
remember that the weight of the inverter offsets the
centre of gravity of the engine. Be careful when
lifting the engine.
The case containing the engine must be preserved and reused
in the cases of resending the engine to the manufacturer,
since it is the only packaging able to ensure the integrity of the
engine during transport. For storage of the case, disassemble
the banks folding them on themselves and stack the platform,
sides and lid in a cool, dry place.

Lift on 3 points
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 seawater.
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. Double exchanger (as an alternative to the diesel
exchanger in the presence of fuel and power steering):
reduces the steering oil and diesel temperature.
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.
11. Raiser or discharge elbow: reduces the temperature of
the exhaust gases coming out of the turbine, conveys
fumes towards the exhaust and prevents the return of sea
water into the turbine.
12. Starter: starts the engine.
13. Water/water exchanger: reduces the temperature of
engine coolant through heat exchange with sea water.
14. Low-pressure electric fuel pump: sucks fuel from the
low pressure line and sends it to the high pressure line.
15. Thermostat housing: contains the thermostatic valve of
the cooling circuit.
16. Sea water pump: sucks water from the sea water intake
and pushes it in the cooling circuit.
17. Alternator: generates electric power, the output voltage is
12 Volt.
18. Oil filler cap: useful in filling the engine oil.
19. Lifting eyes: allow the movement of the engine outside
the engine compartment.
20. Engine label position
21. Serial number position on the crankcase
22. Oil drain valve
