CVVT Oil Control Valve (OCV)





Description

The Continuously Variable Valve Timing (CVVT) system controls the amount of valve overlap by varying the amount of oil flow into a phaser assembly mounted on the intake camshaft through ECM control of an oil control valve.
As oil is directed into the chambers of the CVVT assembly, the cam phase is changed to suit various performance and emissions requirements.
1. When camshaft rotates engine rotation-wise: Intake-Advance / Exhaust-Retard
2. When camshaft rotates counter engine rotation-wise: Intake- Retard / Exhaust- Advance
