VVT solenoid is a vital part of the variable valve timing system. 2010 Ford F150 Vct Solenoid,Vvt Solenoid Ford F150,Vvt Exhaust Solenoid,Intake Valve Timing Control Solenoid Wenzhou Zhongking Parts Co.,ltd , https://www.oemvvt.com
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
