PIPING
The methane piping from the filler to the
pressure regulator/reduction unit is made
from galvanised 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. 4
is 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. 5
, fitted on the in-
take 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. 6
is installed
in the vehicle underbody.
It has the task of separating the excess oil
in the methane.
