PLANT OIL
PURE PLANT OILS (E.G. RAPE SEED OIL, SOY OIL, PALM OIL) ARE NOT CLASSIFIED AS
BIO-DIESEL AND EXHIBIT PROBLEMATICAL PROPERTIES FOR DIESEL ENGINE OPER-
ATION (STRONG TENDENCY TO COKE, RISK OF PISTON SEIZURE, EXTREMELY HIGH
VISCOSITY, POOR EVAPORATION BEHAVIOR.
The conversion of DEUTZ engines to rape seed oil fuel opera-
tion with conversion kits and modified tanks systems of vari-
ous manufacturers is not allowed and leads to loss of warranty
rights.
Biological Contamination In Fuels
SYMPTOMS
The following symptoms may indicate that a fuel tank is con-
taminated by micro-organisms:
• Internal tank corrosion,
• Filter blockage and the associated loss of power due to gel-
like deposits on the fuel filter (especially after long stand-
stills)
CAUSE
Micro-organisms (bacteria, yeasts, funguses) can form bio-
sludge under unfavorable conditions (favoured particularly by
heat and water).
Penetration by water is usually caused by condensation of the
water in the air. Water does not dissolve in fuel so that the pene-
trating water collects at the bottom of the tank. The bacteria and
funguses grow in the watery phase, at the phase boundary to
the fuel phase, from which they draw their nutrition. There is an
increased risk especially with bio-diesel (FAME).
PREVENTIVE MEASURES
• Keep the storage tank clean, regular cleaning of the tank
by specialist companies
• Installation of fuel pre-filters with water traps, especially in
countries with frequently fluctuating fuel qualities and high
percentage of water.
If the fuel system and storage tank have already been attacked
by micro-organisms. The biocide must be dosed according to
the manufacturer's specifications.
• Avoid direct exposure of the storage tank to sunlight
• Use smaller storage tanks with corresponding low dwell
times of the stored fuel
FUEL ADDITIVES
The use of fuel additives is not permitted. The flow improvers
mentioned above are an exception. Use of unsuitable additives
will result in loss of warranty.
