Quality requirements for fuel
Quality requirements for
fuel
Quality requirements and testing standards for
the most important properties of different types
of fuel are described in the Workshop Manual.
This can be ordered from Scania dealers or di-
rectly from Scania.
Diesel
Properties
The quality of the diesel is very important for the
operation and service life of the engine and the
fuel system, and also for the engine performance.
The diesel should comply with the requirements
of European standards EN590 or EN15940.
However, Scania accepts larger tolerances of
certain properties. Please see the table below.
Properties Requirements
Viscosity at 40°C
(104°F)
1.4-4.5 cSt
Density at 15°C (59°F)
0.79-0.87 kg/dm
3
Ignitability (CET rating) minimum 49
Lowest flashpoint 56°C (132°F)
Particulate contamina-
tion level
Classification 22/20/17
according to ISO 4406
Sulphur content
The operator is responsible for using the correct
type of diesel to ensure that local laws are com-
plied with.
Important to use low sulphur diesel
It is important for sulphur-free or ultra-low sul-
phur diesel to be used on engines with SCR sys-
tems certified in accordance with Stage III B/
Tier 4i or Stage IV/Tier 4f to ensure that the en-
gine operates correctly. If diesel with an exces-
sive sulphur content is used, it can cause damage
to the engine and the SCR system.
From January 2011 legislation in the USA and
Europe requires all diesel engines not used on the
road to be run on sulphur-free or ultra-low sul-
phur diesel.
In Europe, diesel must be sulphur-free in accord-
ance with the standard EN 590. This means that
the sulphur content must not exceed 10 ppm.
In the USA, the diesel must be ultra-low sulphur
in accordance with the ASTM D975 standard.
This means that the sulphur content must not ex-
ceed 15 ppm.
