3.25 BIO FUEL IN DEUTZ ENGINES
General
Use of bio fuels is permitted for the compact engines made
by DEUTZ.
Distillate fuels with residue oil percentages or mixed fuels
may not be used in DEUTZ compact engines.
The DEUTZ vehicle engines are designed for diesel fuels
in accordance with EN 590 with a cetane number of at
least 51. DEUTZ engines for mobile machinery are
designed for a cetane number of at least 45. When using
fuels of a low cetane number, disturbing white smoke and
ignition misfires are to be expected under some circum-
stances.
A cetane number of at least 40 is permissible for the US
market, therefore special engine models have been devel-
oped to avoid starting difficulties, extreme white smoke or
increased hydrocarbon emissions (EPA specification -
US EPA REGULATIONS FOR LARGE NONROAD COM-
PRESSION-IGNITION ENGINES).
If the white smoke behavior is unacceptable when using a
very low cetane number, the use of ignition improvers is to
be recommended as a later remedial measure.
The certification measurements for compliance with the
legal emission limits are carried out with the test fuels pre-
scribed by law. These correspond to the diesel fuels in
accordance with EN 590 and ASTM D 975. No emission
values are guaranteed with the other fuels described. It is
the obligation of the owner to check the permission for use
of the fuels in accordance with regional regulations.
Bio Fuel
PERMITTED BIO-DIESEL FUELS
Originally only rape seed oil methylester (RME) was sold
as a bio-diesel fuel in Europe but fatty acid methylester
(FAME) based on other oils have come onto the market
increasingly in recent years. However, with the latter there is
a risk that the limit values of EN 14214 are not kept in the
field. Anyone who uses bio-diesel fuel in DEUTZ engines
must therefore choose his supplier very carefully and have
him guarantee compliance with the EN 14214 limit values.
Since experience has shown that rape seed oil methylester
(RME) exceeds the limit values less often that other esters,
it is expressly recommended to use only rape seed oil
methyester. DEUTZ customers in Germany can addition-
ally ensure the quality by buying bio-diesel fuel with an
AGQM certificate (Arbeitsgemeinschaft Qualitäts-Manage-
ment Biodiesel e.V.).
The use of US bio-diesel based on soy oil methylester is
only permissible in mixtures with diesel fuel with a bio-die-
sel part of a max. 20 weight-%. The US bio-diesel used for
the mixture must comply with the ASTM D6751-07a (B100)
standard.
APPROVED ENGINES
The 912, 913, 914, 1011, 2011, 1012, 2012, 1013, 2013,
413 and 513 series are approved for bio-diesel from year
of manufacture 1993 under compliance with the basic
conditions specified below.
BASIC CONDITIONS TO BE OBSERVED
• A power loss of 5-9 % in relation to diesel fuel in accor-
dance with EN 590 is possible due to the lower heating
value. Blocking of the fuel injector is not allowed.
• The lubricating oil quality must correspond to TR
0199-99-3002. The lubricating oil change interval must
be halved in relation to operation with diesel fuel in
accordance with EN 590.
• Standstills of longer than 4 to 6 weeks must be avoided
with bio-diesel. Otherwise the engine must be started
and stopped with diesel fuel.
• Bio-diesels can be mixed with normal diesel fuel but the
basic conditions described in this subsection apply for
mixtures. Mixtures with up to 5 % (m/m) bio-diesel (B5)
which have recently been on sale at European fuel sta-
tions are excepted. These fuels must be treated like
normal diesel fuels because EN 590 expressly permits
adding up to 5 % (m/m) bio-diesel in accordance with
EN 14214.
• Approx. 30-50 hours after changing over from diesel fuel
to bio-diesel, the fuel filter should be changed as a pre-
ventive measure to avoid a drop in performance due to
clogged fuel filters. Deposited fuel ageing products are
dissolved by bio-diesel and transported into the fuel fil-
ter. They should not be changed immediately but after
approx. 30 to 50 hours because the dissolving of dirt
takes a certain amount of time.
