Description and Operation

Description

Mounted on the intercooler inlet pipe is the RCV (Recirculation Control Valve). The solenoid valve controls the RCV actuator, which operates the bypass passage of the turbocharger compressor. When the throttle is closed while the engine is running at cruising speed (dumping), the turbocharger boost pressure rises rapidly. The pressure wave strikes the compressor blades, causing a chattering noise. To prevent this, the ECM opens the recirculation valve, which allows the excess boost pressure to be released back to the air cleaner side of the turbocharger compressor.
