Protecting The Environment; Diesel Particulate Filter (Dpf) - Alfa Romeo MITO User Manual

Closure
Fit the cap (complete with key) and turn it clockwise until it clicks once
or more. Then turn the key clockwise and extract it, then close the flap.
The sealing may cause a slight pressure increase in the tank. A little
breathing off, while slackening the cap is absolutely normal.
Do not place naked flames or lit cigarettes near to the
fuel filler: fire risk. Also, keep your face away from
this fuel inlet to avoid inhaling harmful fumes.

PROTECTING THE ENVIRONMENT

The following devices are used for reducing petrol fuel engine
emissions: catalytic converter, oxygen sensors and evaporation control
system
The following devices are used for reducing diesel fuel engine
emissions: oxidising catalytic converter, exhaust gas recirculation
system (EGR) and particulate filter (DPF).

DIESEL PARTICULATE FILTER (DPF)

(Diesel Particulate Filter)
(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 is needed to eliminate almost all carbon
particle emissions in compliance with current/future regulations and
standards.
During standard 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 particulate has been trapped by the filter.
Since this filter physically traps particulate, it should be periodically
regenerated (cleaned) at regular intervals by burning carbon particles.
