Diesel fuel must correspond to DIN EN

590.
CZ
2)
no llower tthan 4 49.
RME ffuel ((“diester”)
According to norm DIN 51 606

.
Vehicles with diesel engines can also run
on RME ffuel (Rapeseed Methyl Ester).
Ask a Technical Service Centre or automo-
bile club where biodiesel is available.
See chapter "Filling the tank".
Properties o of R RME
•
RME is chemically produced from veg-
etable oil (predominantly rapeseed oil) in
a process whereby the oil is mixed with
methanol and converted, via a catalyst,
into RME.
•
RME is almost totally sulfur free. The
combustion of RME thus emits practically
no sulfur dioxide (SO
2
).

2)
Cetan-Zahl (Cetane Number). Measure of
diesel fuel ignitability.

DIN preliminary Norm
•
Exhaust gas contains less
– carbon monoxide
– hydrocarbons
– particles (i.e. soot)
than with conventional diesel fuel.
All emission values are lower than legal
requirements.
•
RME fuel is biodegradable.
•
Performance may be slightly lower.
•
Fuel consumption may be slightly
higher.
•
RME can be used in temperatures down
to approximately –10°C.
•
Diesel fuel must be added at ambient
temperatures of less than –10°C to pre-
vent flakes forming in the RME fuel. The
mixing ratio of diesel to RME must be
approximately 50:50.
If tthe R
RME rratio e exceeds 5 50%, ttoo
much s smoke m may b be fformed.
•
During the summer months, RME may
be mixed with diesel at any ratio.
