A continuously variable valve timing mechanism, called a controller or. actuator, is used to adjust the camshaft from the starting stage to the. high speed traveling state. A camshaft timing Oil Control Valve (OCV), controlled by the ECM, directs engine oil pressure to the advance or retard side of the VVT-i. controller. Smooth Idle - At idle rpm, valve overlap is eliminated by retarding the. camshaft.
