FUEL SPECIFICATION TECHNICAL INFORMATION
09
FUEL (DIESEL) : Normal grade compliant diesel conform-
ing to IS1460 or EN 590 or equivalent is recommended to
be used as fuel. Do not use premium diesels available in
the market
for example extra premium / Turbojet etc .
At very low temperature, fluidity of diesel may become
insufficient due to paraffin separation. It is therefore neces-
sary to mix supplementary fuel with summer or winter grade
diesel. The supplementary fuel to be used is kerosene or
aviation turbine fuel. Ratio for mixing of supplementary fuel
and diesel are shown in the table.
Ambient Percentage
Temperature Summer grade Supplementary
upto Deg C. diesel fuel
Upto 0 100 0
0 to -10 70 30
-10 to -15 50 50
Ambient Percentage
Temperature Winter grade Supplementary
upto Deg C. diesel fuel
Upto -15 100 0
-15 to -20 70 30
-20 and below 50 50
Care should be taken that diesel and supplementary fuel
are thoroughly mixed before filling.
WARNING
Do not mix gasoline or alcohol with diesel. This mixture
can cause an explosion.
NOTE
Where oxidation catalytic converter is fitted. It is
mandatory to use Diesel fuel with sulphur contents as
under. Use of any other diesel fuel can increase the
pollutants.
Sulphur Content : 0.035% (BS-IV) / 0.05% (BS-III)
NOTE
Due to precise tolerance of diesel injection systems. It
is extremely important that the fuel be kept clean and
free of dirt or water. Dirt or water in the system can cause
severe damage to Common Rail system
Do not add fuel additives with diesel.
Use low sulphur content fuel having a cloud point that is at
least 10 degree below the lowest expected fuel temperature
at which wax crystals begin to form in diesel.
Viscosity of the fuel must be kept above 1.0 centistokes to
provided adequate fuel system lubrication at 40
