is guaranteed by the appropriate additives in low-sulfur (‹50 mg/kg) or sulfur-free (‹10 mg/kg or ‹15
mg/kg) diesel fuels according to EN 590 and ASTM D 975. In low-sulpur and sulfur-free diesel fuels which
do not comply with this standard, the lubricating capacity may have to be guaranteed by additives. The
parameter for sufficient lubricating capacity is a maximum wear spot of 460 micrometers in the HFRR
test (EN ISO 12156-1).
2.5.1 Fuel for low temperatures
•
When operating the engine in ambient temperatures lower than 0 degrees C, use suitable low
temperature fuel normally available from fuel distributors and corresponding to the specifications
of Tab. 2.3.
•
These fuels reduce the formation of paraffin in diesel at low temperatures.
•
When paraffin forms in the diesel, the fuel filter becomes blocked interrupting the flow of fuel.
2.5.2 Biodiesel fuel
•
Fuels containing 10% methyl ester or B10, are suitable for use in this engine provided that they
meet the specifications listed in the Tab. 2.3.
•
DO NOT USE vegetable oil as a biofuel for this engine.
Biodiesel according to EN 14214 (only permissible for mixture with diesel fuel at max. 10% (V/V))
US biodiesel according to ASTM D6751 – 09a (B100) (only permissible for mixtures with diesel fuel at
10% (V/V))
2.5.3 Synthetic fuels: GTL, CTL, BTL, HV
It is a well-known fact that engines which are operated for longer periods with conventional diesel fuel
and then converted to synthetic fuels suffer shrinkage of polymer seals in the injection system and thus
fuel leaks. The reason for this behavior is that the aromatic-free synthetic fuels can lead to a change in
the sealing behavior of polymer seals.
Therefore, conversion from diesel fuel to synthetic fuel may only be done after changing the critical seals.
The problem of shrinkage does not occur when an engine was operated with synthetic fuel from the start.
2.5.4 Emission-Related Installation Instructions
Failing to follow the instructions in the applications guidebook when installing a certified engine in a piece
of nonroad equipment violates federal law (40 CFR 1068.105(b)), subject to fines or other penalties as
described in the Clean Air Act.
OEM must apply a separate label with the following statement: "ULTRA LOW SULFUR FUEL ONLY" near
the fuel inlet.
Ensure you are installing an engine appropriately certified for your application. Constant speed engines
may only be installed on constant speed equipment for constant speed operation.
If you install the engine in a way that makes the engine's emission control information label hard to read
during normal engine maintenance, you must place a duplicate label on the equipment, as described in
40 CFR 1068.105.5.
