Description |
– |
the CVVT Oil Control Valve (OCV) which supplies the engine
oil to the cam phaser or runs out the engine oil from the cam phaser in
accordance with the ECM PWM (Pulse With Modulation) control signal, |
– |
and the Cam Phaser which varies the cam phase by using the hydraulic force of the engine oil. |
