PROTECTING THE ENVIRONMENT

The devices for curtailing petrol engine emissions are the following:

❒ three-way catalytic converter;

❒ Lambda sensor;

❒ fuel evaporation system.
In addition, do not let the engine run, even for a test, with one or more spark plugs disconnected.
The devices for curtailing diesel fuel engine emissions are the following:

❒ oxidising catalytic converter;

❒ exhaust gas recirculation system (E.G.R.).

❒ diesel particulate filter (DPF)

DIESEL PARTICULATE FILTER (DPF) (for 1.3 Multijet versions 90 HP)
The Diesel Particulate Filter is a mechanical filter, integral with the exhaust system, that physically traps particulates present
in the exhaust gases of Diesel engines.
The diesel particular filter has been adopted to eliminate almost totally particulates in compliance with current / future
law regulations.
During normal use of the vehicle, the engine control unit records a set of data (e.g.: travel time, type of route, temperatures,
etc.) and it will then calculate how much particulates has been trapped by the filter.
Since this filter physically traps particulates, it shall be cleaned (reclaimed) at regular intervals by burning carbon particles.
Reclaiming procedure is controlled automatically by the engine control unit according to the filter conditions and the
conditions of use of the vehicle.
During reclaiming the following phenomena could take place: idling slight increase, fan activation, slight smoke increase,
high exhaust temperatures. These situations shall not be considered as faults and they do not affect vehicle performance
and environment.

DASHBOARD AND CONTROLS

During normal service the catalyst reaches high temperatures. Do not therefore
park the car over inflammable materials (grass, dry leaves, pine needles, etc.): fire
