GETTING TO KNOW YOUR CAR
167
The devices used to reduce diesel fuel en-
gine emissions are:
– oxidising catalyst;
– exhaust gas recirculation system (E. G. R.);
– diesel particulate filter (DPF). DPF (Diesel Particulate Filter)
(for versions/ markets where
applicable)
The Diesel Particulate Filter is a mechani-
cal filter, integral with the exhaust system,
that physically traps particulates present in
the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates in
compliance with current / future law regu-
lations.
During normal use of the car, the engine
control unit records a set of data (e.g.: trav-
el time, type of route, temperatures, etc.)
and it will then calculate how much partic-
ulates has been trapped by the filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular in-
tervals by burning carbon particles.
ENVIRONMENTAL
PROTECTION
The devices used to reduce petrol engine
emissions are:
– trivalent catalytic converter (catalytic si-
lencer);
– Lambda sensors;
– anti-evaporation system.
If one or more spark plugs are discon-
nected, do not run the engine, even for a
test.During normal service the
catalyst and the diesel par-
ticulate filter (DPF) reach
high temperatures. Do not there-
fore park the car over inflammable
materials (grass, dry leaves, pine
needles, etc.): fire hazard.

paragraph “In the event of a burnt fuse”
in this chapter.
– Before changing a bulb check the con-
tacts for oxidation.
– Burnt bulbs must be replaced by oth-
ers of the same type and power.
– Always check headlight aiming after
changing a bulb to ensure they are safe.

charge headlights must on-
ly be replaced by experts: danger
of death! Contact Alfa Romeo Au-
thorized Services.
HALOGEN HEADLIGHTSThe bulbs are arranged inside the light unit
as follows (fig. 22):
(A) Fog lights.
(B) Dipped beam headlights.
(C) Sidelights.
(D) Main beam headlights.
To change the bulbs of the sidelights, low
beams and main beams it is necessary to
remove the cover (A-fig. 23) releasing
the catches (B).

CHECKING LEVELS
Never smoke while work-
ing in the engine compart-
ment; gas and inflammable
vapours may be present, with the
risk of fire.
When topping up take
care not to confuse the var-
ious types of fluids: they
are incompatible with one anoth-
er and could seriously damage the
car.
