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.

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.
