TECHNICAL INFORMATION
EN
KDI Mechanical Injection Tier 3 – Stage IIIA certified Engines (w and w/o EGR)
Those engines are designed for fuels in accordance with EN 590 and ASTM D975 for a cetane number of at least 45. Since
those engines are not equipped with exhaust gas after-treatment, they can be operated with diesel fuels with sulfur content up
to 500 mg/kg (ppm). Compliance with the emission requirements is guaranteed only with sulfur content up to 15 mg/kg (ppm).
Engines operated with fuels as per EN 590 and ASTM D975 with sulfur content < 15mg/kg have an oil changing interval of
500hrs. Fuels with a sulfur content > 500 mg/kg demand a shorter lubricating oil change interval. This is set at 250hrs. However,
the engine oil must be changed when the Total Base Number TBN is reduced to 6.0 mgKOH/g test method ASTM D4739. With
high fuel sulfur content fuel this may happen at 125hrs. Do not use low SAPS oils.
NOTE: In a warranty case the customer must prove by a certificate from the fuel supplier that an allowed fuel was
used.
FUEL COMPATIBILITY
EN 590 (biodiesel content max. 7% (V/V))
ASTM D 975 Grade 1-D S15
ASTM D 975 Grade 2-D S15
NATO F-54, equivalent to diesel fuel in accordance with EN 590
EN 590 or ASTM D 975 Grade 1, 2 -D S15 Arctic Diesel
JIS K 2204 No. 1, No. 2
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.
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.
BIODIESEL COMPATIBILITY
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 selling 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.
FUEL PARAMETER UNIT LIMIT VALUE
Cetane number Min. 49
Fuel density at 15°C Kg/m3 820 - 860
Sulfur content mg/kg or ppm max. 500
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:
