FUELS
DANGER !
Fuels and some fluids on board ships are easily
flammable. 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
compartment. 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.
DIESEL FUEL
Diesel approved by Nanni Industries on the engines of
the firm are as follows :
• EN 590 (Europe),
•
ASTM D975 (U.S.A and territorial waters assimilated,
particularly in the Caribbean and Pacific areas),
• BS 2869 Part 1 Class A1 (G.B),
• JIS KS2204 Fuel N°02 (Japan).
These regulations are in compliance with ISO 8217 DMX.
SULPHUR CONTENT
European Union
:
Low-sulphur diesel (<50 mg/kg sulphur) [EN590], or
sulphur-free (<50 mg/kg sulphur [DIN EN590], [ULSD].
Non-European Union :
Sulphur contained in diesel fuel not in accordance with
EN 590 regulation significantly reduces the performance
of the engine lubricant. More frequent oil changes
are mandatory and also induce much shorter fuel
filter replacement intervals. Request a certificate of
specifications from the fuel distributor and forward it
to the nearest Nanni local representative for advice and
action.
Fuels not intended for the operation of marine engines
or with very high sulphur content can cause irreparable
damage to the engine and are not covered by any
warranty from Nanni Industries.
WINTER DIESEL
Without specific mention, these distributed fuels satisfy
the climates in which they are geographically available.
Generally speaking, summer diesel fuel complying with
EN 590 is usable down to a temperature of 0°C [32°F],
and the winter formulated fuel, down to a temperature
of -20 °C [-4°F] (type No. 01-D in U.S.A). In any case,
consult your local distributor to ensure compatibility of
the fuel.
NOTE !
Additions of petroleum distillates, petrol, solvents,
unapproved additives to improve the fluidity of diesel
fuel at very low temperatures can cause irreparable
engine damage and will void all contractual warranties
and responsabilities from Nanni Industries.
WATER IN FUEL
Water is a non-flammable and incompressible liquid.
For this reason, its presence is particularly harmful
to the operation of the engine and to the entire fuel
injection system. Water easily enters the tank by simple
condensation and especially when it is left or partially
empty. Fill up the fuel tank before storage/winter storage.
Check the water-diesel separator regularly and clean it
as required. Anticipate the replacement of the fuel filter.
If a large quantity of water is present in the tank, drain it
and flush the entire fuel and injection system with clean
diesel fuel. Water in the diesel fuel can cause irreparable
damages to the engine and are not covered by any
warranty from Nanni Industries.
MICROORGANISMS IN FUEL
The presence of water in the tank automatically leads
microorganisms and bacteria to grow and will mix with
the fuel. These microorganisms grow rapidly with a
favorable temperature. Depending on their size, they can
pass through filters and penetrate in the fuel injection
system and cause a total engine failure which is not
covered by Nanni Industries warranty. In the event of
fuel contamination, contact the nearest Nanni agent
who may, if necessary, use an approved disinfectant.
