VVT (Variable Valve Timing) Stator for Automotive Engines
FRING’s Variable Valve Timing (VVT) stators are precision powder metallurgy components that control oil flow to advance or retard camshaft timing. With complex internal oil passages and tight vane slot tolerances, these stators enable fast phaser response and improved engine efficiency and emissions.
