RME f f uel ( ( "diester")
According to norm DIN 51 606
Vehicles with diesel engines can also run
on RME f f uel (Rapeseed Methyl Ester).
Ask a Technical Service Centre or automo-
bile club where biodiesel is available.
See chapter "Filling the tank".
Properties o o f R R ME
•
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

TIPS AND MAINTENANCE
•
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 must be added at ambient tem-
peratures of less than –10 °C to prevent
deterioration of the biodiesel due to low
temperatures. The mixing ratio of diesel
to biodiesel must be approximately
50:50.
If t t he R R ME r r atio e e xceeds 5 5 0%, t t oo
much s s moke m m ay b b e f f ormed.
•
During the summer months, RME may
be mixed with diesel at any ratio.
