The VVT oil control valve (OCV) body is a critical component in modern engines, primarily used to regulate oil pressure flow, thereby controlling the variable valve timing (VVT) system's operation. Its structure typically includes a valve body, valve plug, blocking piece, and spring, which work in concert to ensure precise control and responsiveness of oil flow.

●  Function: The OCV adjusts the supply pressure of oil to influence the timing of valve openings and closings, optimizing engine performance, enhancing fuel efficiency, and reducing emissions.

●  Operation: The OCV modulates oil flow based on engine load and speed through a pulse-width modulation signal, precisely controlling the displacement of the VVT sprocket for accurate valve adjustment.

●  Applicability: This component is widely used across various vehicle types, particularly in modern automobiles where high performance and efficiency are paramount.
