Hyundai Elantra HD: CVVT Oil Control Valve (OCV). Description and Operation
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..
