The solenoid valves are open when:

the switching button is in the

methane position;

the pressure in the cylinder is

sufficient for operation;

the engine is running;

The solenoid valve assembly is

equipped with the following safety

devices:

1) Fuse pad

: in the event of

overheating (temperature above 110

°

C), it totally eliminates the danger of

excess pressure making the methane

in the cylinder flow out as quickly as

possible in a controlled manner.

2) Mechanical excess pressure

device (Burst Disk)

: in the event of

excess pressure (above 330 bar), it

ensures that the methane escapes

as quickly as possible in a controlled

manner.

3) Excess flow device

: intervenes

if the pipes break and limits the flow

of methane exiting to non dangerous

levels.
The flow restrictor valve is located to

allow it to operate even if the solenoid

valve casing is broken due to an

impact.

4) Manual tap

: positioned upstream of

the solenoid valve.

This separates the cylinder from the

methane system to allow maintenance

operations.
The taps are accessible from outside

the vehicle and are located, in the case

of the lengthwise middle cylinder, at the

rear of the cylinder and, in the case of

the transverse rear cylinder, towards

the wheel right side.
To close the taps (D) fig. 115: turn the

knob in the direction (1) shown by the

arrow (clockwise OFF).
To open the taps (D) fig. 115: turn the

knob in the direction (2) shown by the

arrow (anticlockwise ON).

5) Check valve

, this prevents the

methane from flowing back to the filler.

PIPES

The methane piping from the filler to

the pressure regulator/reduction unit

is made from galvanised steel and

covered in plastic (high pressure) and

is located outside the passenger

compartment; the piping from the

pressure regulator/reduction unit to the

methane injectors is in stainless steel.

PRESSURE

REGULATOR/REDUCTION

UNIT

The pressure reduction unit fig. 116 is

installed in the engine compartment.
It reduces the pressure of the methane

from the value in the cylinder to the

supply value for the methane injectors

(about 6 bar) and keeps it constant in

all operating conditions.

KNOWING YOUR VEHICLE

METHANE INJECTORS

There are four dedicated Methane gas

injectors (A) fig. 117, 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

operated by the electronic control unit.

117

F0T0351

PETROL/METHANE

SWITCH

This engine normally runs on methane

except during starting when it runs on

petrol. Switching to methane takes

place automatically and is shown

on the instrument panel display by

switching off the

signal in the

display.

7)

METHANE FUEL RESERVE

The level of methane in the cylinders is

indicated by the four vertical bars near

the word CNG on the instrument panel

display fig. 118. When the residual

amount of methane is lower than 1/5

of the capacity of the cylinders, the

first level and the edges of the bars of

the other 3 levels flash until the next

methane refuelling. A specific message

will appear on the display in addition to

an acoustic warning.

118

F0T0462

If the methane has run out, switching

to petrol takes place automatically.

In this case, the display shows the

icon just above the CNG wording and

all the bars of the edges for the empty

notches light up constantly, regardless

of the type of supply; see fig. 119 or

fig. 120.

119

F0T0382

120

F0T0383

If you want the car to run on petrol,

press the button fig. 121 located

between the controls in the dashboard.

The LED on the button switching on

indicates that the request for switching

has taken place correctly.

61

121

F0T0343

The actual change to the chosen fuel

system takes place depending on the

vehicle usage conditions to guarantee

switching in absolute safety and will

be confirmed by the

warning light

in the instrument panel display coming

on/going off.

Manual switching of the operating

mode from petrol to methane and

vice versa only occurs if the engine

speed is below 2000 rpm.

8)

In addition, in the case of starting at

outside temperatures of below around

-10

°

C, the switching times from Petrol

to Methane increase to allow the

pressure regulator/reduction unit to

become warm enough.

WARNING If switching takes place

during acceleration or pick-up, there

may be a brief flat spot (drop in power).

9)

CNG SYSTEM FAILURE

In case of CNG system failure, all the

CNG fuel levels will turn off on the

display and the symbol "!" will appear

together with a dedicated message. In

this case, contact a Fiat Dealership as

quickly as possible.

7)

Regardless of the last fuel system used,

at the following engine starting, after

the initial petrol stage, the system will

automatically switch to methane.

8)

When switching is requested, metallic

noise from the valves which pressurise

the circuit can be heard. For the switching

logic described above, a delay between

the valve ticking and the switching off the

indication on the instrument panel display.

9)

Do not switch between the two

operating modes whilst starting the

engine.

PROTECTING THE

ENVIRONMENT

The following devices are used for

reducing petrol fuel engine emissions:

three-way catalytic converter

Lambda sensors

evaporation control system.

In addition, do not let the engine run,

even for a test, with one or more spark

plugs disconnected.

The following devices are used for

reducing diesel fuel engine emissions:

oxidising catalytic converter;

exhaust gas recirculation system

(EGR);

particulate filter (DPF) (for

versions/markets, where provided).

DIESEL PARTICULATE

FILTER (DPF)

(for versions/markets, where provided)
The Diesel Particulate Filter is a

mechanical filter, integral to the exhaust

system, that physically traps carbon

particles present in the exhaust gases

of diesel engines.
The diesel particulate filter has been

adopted to eliminate almost all

particulates in compliance with current

/ future legal regulations.
During normal use of the vehicle, the

Powertrain Control Module records a

set of data (travel time, type of route,

temperatures reached etc.) and

KNOWING YOUR VEHICLE

62

calculates how much particulate has

been trapped by the filter.
Since this filter physically traps

particulate, it should be regenerated

(cleaned) at regular intervals by burning

carbon particles. The regeneration

procedure is controlled automatically

by the Powertrain Control Module

according to the filter conditions and

vehicle usage conditions.
During regeneration, the following

may occur: a limited increase in the

engine speed, activation of the fan, a

limited increase in fumes and high

temperatures at the exhaust.
These are not faults; they do not impair

vehicle performance or damage the

environment. If the dedicated message

is displayed, refer to paragraph

"Warning lights and messages".

F0T0804

REV COUNTER

The rev counter shows the number of

engine revolutions per minute.

WARNING The electronic injection

control system gradually shuts off the

flow of fuel when the engine is over-

revving, resulting in a gradual loss of

engine power. When the engine is

idling, the rev counter may indicate

a gradual or sudden increase of the

speed.

127

F0T0805

This is normal and does not indicate a

fault. It may be caused, for example,

by the activation of the climate control

system or fan. In these cases, a slow

change in revs is used to protect the

battery charge.

FUEL LEVEL GAUGE

This shows the amount of fuel left in the

fuel tank.
Warning light (A) fig. 128 comes on to

indicate that approximately 6-7 litres of

fuel are left in the tank.
(E) - tank empty.
(F) - tank full (see the description in

paragraph "Vehicle refuelling" in this

chapter).
Do not travel with the tank nearly empty

to prevent damaging the catalytic

converter.

F0T0806

WARNING The needle will point to (E)

and the warning light (A) will flash to

indicate a fault in the system. If this

is the case, go to a Fiat Dealership to

have the system checked.

INDICATOR

This shows the temperature of the

engine coolant fluid and starts working

when the fluid temperature exceeds

approx. 50

°

C. In normal use, the

needle could assume different positions

within the scale, depending on the

usage conditions.
(C) - Low engine coolant temperature.
(H) - High engine coolant temperature.
Warning light (B) fig. 128 may switch

on (together with a message on the

display) to indicate that the coolant

temperature is too high; in this case,
