CVVT Oil Control Valve ( OCV)

CVVT OIL CONTROL VALVE (OCV)




FUNCTION AND OPERATION PRINCIPLE
The Continuously Variable Valve Timing (CVVT) system controls the amount of valve overlap by varying the amount of oil flow into an assembly mounted on the intake camshaft through ECM control of an oil control valve. An Oil Temperature Sensor (OTS) is used to allow ECM monitoring of engine oil temperature. 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
