Air Intake Control Circuit

CIRCUIT DESCRIPTION




The air cleaner inlet is divided into two areas, and a air intake control valve and an actuator have been provided in one of the areas.

As a result, a reduction in intake noise and an increase in the power output have been realized in the low to the high-speed range of the engine.

When the engine is operating in the low-to mid-speed range, this control operates the air intake control valve to close one side of the air cleaner inlet.

When the engine speed is more than 3600 r/min. and the opening of the throttle valve is more than 30°, the ECM activates VSV ON and operates AICV.
