STORING FUEL
DANGER !
Fuels and some fluids on board ships are easily flamma-
ble. Handle fuels with care and respect all safety rules.
Do not refuel the tank while the engine is running. Do not
smoke during the filling process or in the engine compart -
ment. Ventilate the engine compartment before starting.
Wear protective gloves and eye protective glasses. Avoid
synthetic clothing which can melt when ignited. Always
keep a fire extinguisher nearby.
If there is a very slow turnover of fuel in the fuel tank or
supply tank, it may be necessary to add a fuel conditioner
to prevent water condensation. Contact your NANNI deal-
er for proper service or maintenance recommendations.
DIESEL FUEL
Consult your local fuel distributor for properties of the
diesel fuel available in your area.
In general, diesel fuels are blended to satisfy the low tem-
perature requirements of the geographical area in which
they are marketed.
Diesel fuels specified to EN 590 or ASTM D975 are recom -
mended. Renewable diesel fuel produced by hydro-treat-
ing animal fats and vegetable oils is basically identical
to petroleum diesel fuel. Renewable diesel that meets EN
590, ASTM D975, or EN 15940 is acceptable for use at all
percentage mixture levels..
Required Fuel Properties
In all cases, the fuel shall meet the following properties:
• Cetane number of 40 minimum. Cetane number
greater than 47 is preferred, especially for tempera -
tures below –20 °C (–4 °F) or elevations above 1675
m (5500 ft.).
• Cloud Point should be below the expected lowest
ambient temperature or Cold Filter Plugging Point
(CFPP) should be a maximum 10°C (18°F) below the
fuel cloud point.
• Fuel lubricity should pass a maximum scar diame-
ter of 0.52 mm as measured by ASTM D6079 or ISO
12156-1. A maximum scar diameter of 0.45 mm is
preferred.
• Diesel fuel quality and sulfur content must comply
with all existing emissions regulations for the area
in which the engine operates. DO NOT use diesel fuel
with sulfur content greater than 10 000 mg/kg (10
000 ppm).
E-Diesel fuel
DO NOT use E-Diesel (Diesel fuel and ethanol blend).
Use of E-Diesel fuel in any NANNI engines may void the
machine warranty
CAUTION !
Avoid severe injury or death due to the fire and explosion
risk from using E-Diesel fuel.
Sulphur Content for Tier 3 and Stage III A Engines
• Use of diesel fuel with sulphur content less than 1000
mg/kg (1000 ppm) is RECOMMENDED.
• Use of diesel fuel with sulfur content 1000—2000
mg/kg (1000—2000 ppm) REDUCES the oil and filter
change interval.
• BEFORE using diesel fuel with sulfur content greater
than 2000 mg/kg (2000 ppm), contact your NANNI
