Permitted sulfur contents
Permitted sulfur content depends on:
• emission level
• fuel injection components and materials
• aftertreatment components and materials.
For engines with SCR system and engines with cooled external EGR system (cEGR), fuels with higher
sulfur content are not permitted because engines do not fulfill particulate emission limits with high sulfur
fuel. Sulfur is also a catalyst poison, which can lead to catalyst deactivation in long term use. Deactivation
will cause malfunction of the aftertreatment system.
IMPORTANT:
Use of high sulfur fuel in SCR engines and cEGR engines will lead to severe damage to
emission aftertreatment components and cause the machine to derate. Warranty of the engine and
exhaust aftertreatment system will be voided if high sulfur content fuels are used.

If the engine does not have SCR system or cooled external EGR system, maximum permitted sulfur content is
500 mg/kg.
Cetane number
Cetane number must be minimum 43. Cetane number above 47 is preferred, especially for temperatures
below -20°C (-4°F) and elevations above 1500m (5000 ft) from the sea level.
Biodiesel blends
1st generation biodiesel blends
Use of 1st generation biodiesel, which has less than 10% fatty acid methyl esters (FAME) / fatty acid
mono-alkyl esters (FAAE), does not require changes in engine or its maintenance.
