EXHAUST GAS RECIRCULA
T ION
(EGR) SYSTEM
GENERAL INFORMAT ION (EGR SYSTEM)
M1173 0052 0032 7
The exhaust gas recircu l atio n (EGR) system lowers
the nitrogen
oxide (NOx) emission level.
When the air/fuel mixture combus tio n temp erature is
high,
a larg e qua ntity of nitrogen oxides (NOx) is
generat
ed in the comb ustion chamb e r .
Therefor e, this syst em re circulat es p a rt o f emission
gas fro
m the e x ha ust po rt of the cylinder h ead to th e
combust
i on chamber thro ugh th e int a ke ma nifold to
decre
ase the air/fuel mixture combust i on te mpera
-
ture, resulting in redu ctio n of NOx.
The EGR flow rate is cont rolle d by the EGR valve so
as no
t to de crease the driveability .
OPERAT ION
The EGR valve is being clos ed an d does not re circu-
late ex hau st ga ses unde r one o f the fo llo wing condi-
tions.
Otherwise, th e EGR va lve is opene d an d recircul ates
exha
ust g a ses.
•The engine coolan t temperature is low .
•The engine is at idle.
•The throttle va lve is widely ope ned.
