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.

What is the working principle of a VVT phase shifter?

The core operating principle of a VVT phaser is to dynamically adjust the timing of valve opening and closing by using hydraulic actuation to change the relative phase between the camshaft and the crankshaft, thereby optimizing engine performance, fuel economy, and emissions under various operating conditions.

What are the adjustable angles and locking types available for VVT phase adjusters?

The adjustment angle of the VVT phase shifter is measured in crankshaft angle (CA) units, and the locking mechanism is compatible with the mainstream hydraulic vane-type structure.
