Temperature dependence of diesel fuel
At temperatures lower than those specified for the diesel
fuel, paraffin wax may precipitate from the fuel and block
filters and pipes. The engine can then loose power or stop.
The diesel fuel is adapted for use in the specific climate of
each country. If a vehicle or an engine is to be operated in a
temperature zone with lower temperature than normal, first
identify the temperature properties of the fuel concerned.
The properties of the fuel when cold can be improved by
adopting one of the following measures before the tempera-
ture drops:
- If the fuel concerned cannot cope with the expected
temperatures, and diesel fuel is not available with the
correct temperature properties, we recommend that
an electric fuel heater is installed as a preventative
measure.
- The low temperature properties of diesel fuel may
be improved by adding kerosene as a preventative
measure. A maximum of 0% may be added. When
refuelling, the kerosene should be added first, so that
it mixes thoroughly with the diesel fuel.
Note:
It is prohibited to use kerosene in engine fuel
in some countries.
- To prevent water in the fuel from freezing and
forming ice, a maximum of 0.5-% alcohol
(isopropanol) may be added.
Drain fuel tanks and drain or change fuel fil-
ters regularly.
Warning
It is not permitted to mix
kerosene with diesel fuel that is
already adapted for the climate
concerned. This can damage
the
PDE injectors. All use of
paraffin other than kerosene is
forbidden, as it causes engine
damage.
!
Important
It is not permissible to mix
petrol with diesel fuel. In the
long term, petrol may cause
wear to the PDE injectors and it
may also cause damage to the
engine.
