PROTECTING THE
ENVIRONMENT
Environmental protection has
governed every stage in the design
and production of the Fiat Strada.
This has resulted in the use of
materials and the calibration of
devices which reduce or drastically
limit negative environmental impact.
The following devices are used for
reducing diesel engine emissions:
– oxidising catalytic converter;
– exhaust gas recirculation system
(E.G.R.).
– particulate filter (DPF).

DIESEL PARTICULATE
FILTER (DPF)
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 particulate filter has been
adopted to eliminate almost all
particulates in compliance with
current/future legal regulations.
During normal use of the vehicle,
the engine management control unit
records a set of data (travel time,
type of route, temperatures, etc.)
and it will then calculate 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 managed
automatically by the engine
management control unit according
to the filter conditions and vehicle
use 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
Warning lights and messages in this
section.
