PROTECTING THE ENVIRONMENT
The devices for reducing petrol engine emissions are the
following:
❍ three-way catalytic converter;
❍ Lambda sensors;
❍ fuel evaporation control system.
In addition, do not let the engine run, even for a test, with
one or more spark plugs disconnected.
The devices for reducing diesel fuel engine emissions are
the following:
❍ oxidising catalytic converter;
❍ exhaust gas recirculation system (E.G.R.).
❍ diesel particulate filter (DPF) (for versions/markets,
where provided).
The catalytic converter reaches high temper-
atures during operation. Do not park on
grass, dry leaves, pine needles or other flam-
mable material: fire risk.
DIESEL PARTICULATE FILTER (DPF)
(for versions/markets, where provided)
The Diesel Particulate Filter is a mechanical filter, inte-
gral with the exhaust system, that physically traps par-
ticulate present in the exhaust gases of Diesel engines. The
diesel particular filter has been adopted to almost totally
eliminate particulate in compliance with current / future
regulations. During normal use of the car, the engine man-
agement control unit records a set of data (e.g.: travel time,
type of route, temperatures reached, etc.) and it will then
calculate the amount of particulate trapped by the filter.
Since this filter physically traps particulate, it should be
regenerated (cleaned) at regular intervals by burning car-
bon particles. The regeneration procedure is controlled au-
tomatically by the engine management control unit ac-
cording to the filter conditions and car use conditions. Dur-
ing the regeneration procedure, the following situations
may occur: limited increase of idle speed, activation of
electric fan, limited increase of smoke, high temperatures
at the exhaust. These are not faults; they do not impair
car performance or damage the environment. If the ded-
icated warning message is displayed, refer to the section
“Instrument panel warning lights” in this chapter.
