• 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 Non-Road Fuels
Other non-road fuels may be used if they comply with all the limit values of EN 590 except for the fuel
density, the cetane number and the sulfur content.
The following limits apply for these parameters:
FUEL PARAMETER
Cetane number
Fuel density at 15°C
2.5.5 Jet Fuels
Only for KDI Mechanical Injection Uncertified Engines (no EGR Engines).
The following jet fuels can be used but only adopting an additional fuel filter with lubricity doser:
F-34/F-35 (kerosene, NATO designation)
F-63 (kerosene, NATO designation, equivalent to F-34/F-35 with
F-65 (kerosene, NATO designation, 1:1 mixture of F-54 and F-34/F-
2.5.6 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.
