Protecting the environment has been the guiding principle in the design of the Fiat Doblò right from the start.

The result is the use of materials and creation of devices that can reduce or considerably curtail harmful influences on the environment.

The devices for curtailing petrol engine emissions are the following:

– a three-way catalytic converter;

– Lambda sensors (oxygen sensors);

– a fuel evaporation system.

The devices for curtailing diesel engine emissions are:

– an oxidizing catalytic converter;

– an exhaust gas recirculation system (E.G.R.).

– diesel particulate filter (DPF)

– Lambda probes (where provided).

Consequently, the Fiat Doblò is ready to travel well ahead of the most stringent international pollution control standards.

DIESEL PARTICULATE FILTER (DPF) (for Multijet versions 1.3 85 HP and 1.9 120 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.
