G 2.2.1.
Fuel
--- The properties of light fuel oil that is only intended for
warming use do not meet the requirements of modern
diesel engines and cannot be used as fuel.
--- In particular, distributor---type injector pumps require the
fuel to have sufficient lubricity, because they do not
have oil lubrication in the same way as typical multi---el-
ement pumps. Adding oil to diesel fuel is not recom-
mended, because it causes carbon build---up, and if oil
is mixed with even a small amount of water it will clog
the filter.
--- Additionally, various fuel quality requirements imposed
by taxation and seasonal changes have to be taken into
consideration.
G 2.2.2.
Fuel storage
--- Storing and distributing fuel must be arranged in condi-
tions where no water or impurities can enter the storage
tanks. The storage tanks must be installed in a slanted
position, so that water and impurities are collected at
the opposite end from the suction pipe of the pump.
The suction pipe of the pump should not reach the bot-
tom of the tank.
--- Water must be periodically drained from the tank in
order to prevent problems. Refueling at the same time
the tank is being refilled must be avoided without excep-
tion.
--- When the tank is filled with winter---quality fuel in good
time, the engine is guaranteed to run flawlessly during
the cold season.
G 2.2.3.
Filter system
--- The engine’s standard filter system gives sufficient
protection for the injection system from impurities that
can be present in well---tended distribution systems.
--- The control of distributor---type injection pumps is
based on internal pressure, which will drop if the fuel
system is clogged. If the pilot pressure drops too low,
engine power is reduced, smoke increased and starting
becomes more difficult. Additionally, water in the injec-
tion system will destroy it in a very short time.
For this
reason, the water trap and the filters must always be
serviced according to the specified amount of run-
ning hours
.
--- It is also important always to use original Valtra (or Sisu
Diesel) fuel filters. They guarantee sufficient filtration,
preventing impurities from damaging the fuel system.
There are many cheap filter kits (so---called pirates) on
the market, with lower quality and performance in order
to minimise the cost. Among other things, the quality
and amount of filter paper are often insufficient. There
are also often dangerous defects in the basic structure
that may cause expensive damage even in a short
period of time.
