FUEL SPECIFICATIONS
The quality of fuel used for high-speed diesel
engine operation is a very important factor in
obtaining satisfactory engine performance, long
engine life and acceptable exhaust emission
levels.
The U.S. Environmental Protection Agency
(EPA) has issued new standards to improve air
quality by significantly reducing emissions
through a combination of cleaner-burning diesel
engines and vehicles.
To meet EPA standards, the petroleum industry
produces Ultra Low Sulfur Diesel (ULSD) fuel,
also referred to as S15, containing a maximum
of 15ppm (parts-per-million) sulfur.
On-highway diesel engines meeting 2010
emission regulations are designed to operate
ONLY with ULSD fuel. ULSD fuel will enable the
use of cleaner technology diesel engines and
vehicles with advanced emissions control
devices, resulting in significantly improved air
quality.
4.5 FUEL TYPE
EPA-10 and later engines like the Volvo D13 are
designed to run on Ultra Low Sulfur Diesel
(ULSD) fuel, which can contain no more than 15
ppm sulfur.
Fuel used must meet engine manufacturer’s
specification. Refer to Volvo engine
specifications.
CAUTION
ULSD fuel is necessary to avoid fouling the
engine’s Exhaust Aftertreatment System.
Improper fuel use will reduce the efficiency of
the engine’s Aftertreatment System and may
permanently damage the system.
NOTE
Burning Low Sulfur Diesel fue
l (instead of
ULSD fuel) in 2010 and later model year diesel
engines is illegal and punishable with civil
penalties.
NOTE
Like Low Sulfur Diesel fuel, ULSD fuel requires
good lubricity and corrosion inhibitors to
prevent unacceptable engine wear. As
necessary, additives to increase lubricity and
to inhibit corrosion will be added to ULSD fuel
prior to its retail sale.
4.6 BLENDING
Only ultra low sulfur kerosene – No.1 diesel with
no more than 15ppm sulfur may be blended with
ULSD fuel to improve cold weather performance.
With so many kerosene formulations on the
market, care must be taken to select kerosene
with a maximum of 15ppm sulfur.
Blend rates remain the same as with Low Sulfur
Diesel fuel.
4.7 BIODIESEL FUELS
Biodiesel up to a maximum of 5% blend (B5)
may be used and will not affect the
manufacturers’ mechanical warranty as to
engine and emissions system related
components, provided the biofuel used in the
blend conforms to ASTM D6751, B1 to B5
blends conform to ASTM D975. Also, any engine
performance problem related to the use of
biodiesel fuel would not be recognized nor
considered as Volvo or Prevost’s responsibility.
However, Volvo engines are certified to comply
with U.S. EPA and California emissions
standards based upon the use of test fuels with
specifications established by these regulatory
agencies.
Alternative fuels, including biodiesel, that are not
substantially similar to the required test fuels
may adversely affect engine emissions
compliance. As a result, Volvo does not warrant
the engine will conform to applicable Federal or
California emissions limits when operated on
biodiesel or other alternative fuels that are not
substantially similar to specified test fuels used
for certification.
Additional maintenance care must be carried-out
for the following systems:
4.7.1 Biodiesel Fuels and the Engine
Use an oil sampling method to establish the
appropriate oil drain interval for your application.
