ENVIRONMENTAL PROTECTION
SYSTEMS
Petrol versions
The following systems are used for
reducing petrol fuel engine emissions:
catalytic converter, oxygen sensors and
evaporation control system.
Diesel versions
The following systems are used for
reducing Diesel fuel engine emissions:
oxidising catalytic converter, exhaust gas
recirculation system (EGR) and
particulate filter (DPF).
30)
DIESEL PARTICULATE FILTER (DPF)
(Diesel Particulate Filter)
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
Powertrain Control Module 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.
The regeneration procedure is controlled
automatically by the engine management
control unit according to the filter
conditions and vehicle use conditions.
During the regeneration there may be a
limited increase in the engine idle speed,
fan activation, a limited increase in fumes
and high temperatures at the exhaust.
These are not faults; they do not impair
normal vehicle performance or damage
the environment. If the dedicated
message is displayed, see contents of
"Warning lights and messages"
paragraph, in chapter "Knowing the
instrument panel".
WARNING
30) The catalytic converter and particulate
filter (DPF) reach very high temperatures
during operation. Therefore do not park the
vehicle on flammable materials (e.g. grass,
dry leaves, pine needles, etc.): fire hazard.

ACTIVE AERODYNAMICS

FRONT MOBILE SPOILER (Alfa Active
Aero)
This is an automatic device, working at
the vehicle speed, which allows higher
reactivity at average speeds and higher
vehicle stability at high speeds,
regulating the air flow into the lower part
of the vehicle.
The system is not active in temperatures
near or below zero, or when the "Alfa
DNA™ Pro" selector is in the "Normal" or
"Advanced Efficiency" positions.
86
In case of a faults, the generic failure icon
along with a message which identifies the
type of malfunction, light up on the
instrument panel display.
