1. The OCV control valve is integrated in the center bolt, the VVT working oil circuit is short, and the electromagnet receives the ECU control signal to drive the control valve to control the VVT oil channel and realize the variable valve timing of the engine
2. Compared with the side-mounted VVT, the phase modulation is faster, and the OCV is integrated in the center bolt, saving the engine cylinder head oil line processing."
3. Use the positive basalt torque of the camshaft rotation to realize oil circulation inside the VVT control valve, reduce oil consumption, and improve phase regulation speed
4. Compared with ordinary middle, the engine oil pump capacity is low, and the phase down speed is fast in low oil pressure conditions."
5. The VVT is locked in the middle position and coordinated with Atkinson cycle technology to achieve VVT advance or lag adjustment.
6. Support for Atkinson/Miller cycles with higher phase range and mid-lock position at lower cost compared to electric VVTS"""
