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 rpm and the opening of the throttle valve is more than 30°, the ECM activates VSV ON and operates AICV.
