Let me introduce the working principle of the OCV valve.
The OCV valve (Oil Control Valve, or Oil Control Valve) is the core electronically controlled actuator of the VVT variable valve timing system. Its fundamental operating principle is to receive electrical signals from the ECU and precisely adjust the oil pressure and flow direction to the VVT phase shifter, thereby controlling the rotation of the phase shifter’s rotor and enabling dynamic adjustment of the valve timing.
