PIPING
The methane piping from the filler to the
pressure regulator/reduction unit is made
from galvanized steel and covered in plas-
tic (high pressure) and is located outside
the passenger compartment; the piping
from the pressure regulator/reduction
unit to the methane injectors is in stain-
less steel.
PRESSURE
REGULATOR/
REDUCTION UNIT
The pressure reduction unit Fig. 8is in-
stalled in the engine compartment.
It has the task of reducing the pressure
of the methane from the value in the can-
ister to the supply value for the methane
injectors (about 6 bar) and keeping it con-
stant in all operating conditions.
METHANE INJECTORS
There are 4 dedicated injectors for the
methane gas A-Fig. 9, fitted on the intake
manifold near the cylinder head, one for
each intake duct; they are supplied at a
constant pressure (about 6 bar) and op-
erated by the electronic control unit.
OIL SEPARATOR FILTER
The oil separator filter Fig. 10is installed
in the engine compartment.
It has the task of separating the excess oil
in the methane.
PETROL/
METHANE SWITCH
This engine normally runs on methane ex-
cept during starting when it runs on
petrol. Switching to methane takes place
automatically and is shown on the instru-
ment panel display by the Ksignal in the
display going out fig. 12.
