The system is situated inside the air filter case, contains a valve
for checking air flow underneath the throttled body throttles and
is equipped with a stepper motor.
The system controls the following parameters:
•
Idle speed
•
Air supply in case of engine overspeed
•
Adjustment of air/fuel ratio by working at idle speed at
altitudes above sea level.
•
Adjustment of air/fuel ratio in cold/hot setting-off.
When the stepper motor is activated, it opens the valve that
controls the air flow and allows a certain air flow to run off along
a series of hoses in the throttled body unit.
