ANTIPOLLUTION
Oil vapour rebreathing circuit: Descriptions
K9K
14A
I - PRESENTATION OF THE CIRCUIT
Operating phase A
Operating phase BOperating phase A :
-with the engine at low load, the vacuum in the air pipe
at the air filter box outlet is not sufficient to activate the
membrane of the oil vapour rebreathing valve, fitted
with a weighted spring. Oil vapours are aspirated in
large quantities due to the vacuum in the air pipe at
the air filter box outlet.
Operating phase B :
-At engine medium and high load, the vacuum in the
pipe at the air filter box outlet attracts the membrane
of the oil vapour rebreathing valve. The hole allowing
the oil vapours to pass through in large quantities is
therefore closed and the oil vapours are aspirated in
low quantities via a calibrated jet.
II - CHECK
To ensure the antipollution system works properly, the
oil vapour rebreathing circuit must be kept clean and in
good condition.

CONDITIONS
aThe fuel vapour absorber bleed solenoid valve is
controlled by the computer.
During « on board diagnostic » fault finding, fuel va-
pour absorber bleeding is not authorised.
The opening cyclic ratio of the fuel vapour absorber
bleed solenoid valve can be viewed on the Diagnos-
tic tool by reading parameter « Fuel vapour absorb-
er bleed solenoid valve OCR » .
The solenoid valve is closed for a value below 1.2%. Equipment required

REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aDisconnect the battery (see Battery: Removal - Re-
fitting) (80A, Battery).
II - REMOVAL OPERATION
aUnclip:
-the fuel filter on the fuel vapour absorber in the di-
rection of the arrow (1) ,
-the fuel vapour absorber in the direction of the ar-
row (2) . IMPORTANT
During this oper ation, be sure to:
-refrain from smoking or bringing red hot objects
close to the working area,
-be careful of fuel splashes when disconnecting the
union.
IMPORTANT
Wear goggles with side protectors for this opera-
tion.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run.
WARNING
Keep the pipe unions away from contaminated
areas.
WARNING
To prevent impurities from entering the circuit, place
protective plugs on all fuel circuit components
exposed to the open air.
