6.5. Fuel System
CIRCUIT DESCRIPTION
The fuel system is based on a fuel feed pump and an in-line mechanical injection pump.
ELEMENT
1
Fuel injection Nozzle
2
Fuel injection pipe
3
Leak-off pipe
4
Injection pump
5
Feed pump
6
Fuel filter
7
Tank (supplied as accessory)
8
Fuel decanting filter (accesory)
9
Fuel intake pipe (accessory)
FUEL SPECIFICATIONS
Use
ASTM diesel fuel No.2-D
for the best engine performance, to prevent engine damage.
Never use kerosene, heavy diesel fuel or biodiesel. It is essential to use clean and filtered diesel oil.
The use of diesel oil that not complies with the technical specifications may affect
warranty coverage and cause serious damage in the injection system and internal engine
components.
MAINTENANCE TASK. FUEL LEVEL INSPECTION
Periodically, it is necessary to check the fuel level to assure the operation of the engine.
On top of that, if fuel pump sucks air when the fuel level is lower than pump suction, it could
break.
Whenever possible, keep the fuel tank full. The temperature changes may cause
condensation of the damp air present in the tank and this water accumulates at the bottom. It
can cause an increase of corrosion or an impossibility of starting the engine if this water is aspired
by the fuel pump.
MAINTENANCE TASK. FUEL TANK CLEAN
The fuel impurities could obstruct the suction pump. For this reason, drain out the content
of the fuel tank to remove condensate and any foreign material. Then, wash the tank with fuel
and refill it.
MAINTENANCE TASK. WATER SEPARATOR FILTER PURGUE
The fuel system has to have a water separator filter (supplied as
accessory) to avoid the inlet of water in the fuel circuit. According to the
maintenance plan it is necessary to purge the filter to eliminate water
periodically. This is the procedure:
1.
Loosen the bottom nut to eliminate water.
2.
Shut it off again.
3.
Check for any leakage.
