WASTE GATE CONTROL

WASTE GATE CONTROL
M2132013000078
Turbo pressure used in the waste gate actuator is
controlled by duty control of the waste gate solenoid
valve. As a result, turbo pressure corresponding to
driving conditions can be obtained.

The eng

whe
n normal curren t (duty 100% ) flows in th e waste
gate solen
o id valve coil, the waste gat e solenoid valve do es n o t ope n if tu rbo pre ssu re does not rise
above the set pre s sure of th e waste gate actua t or
spring since some of the turb o pressure used in th e
wa ste g a te actuato r leaks o u t.
On the ot
her hand, when current do es not flow in the
wa
ste g a te soleno id valve co il (d uty 0 % ), the wa ste
gate valve ope
ns if turbo pressure rise to the set
pressure o
f the waste gat e act uator sprin g since no
pressure leaks out
.
Conseq uently , by u s in g duty co ntrol for the waste

in a range
f r om 0% to 1 00% duty . Th is du ty co ntrol is
performed in cycles of
approximately 60ms.
