Engine Camshaft Adjuster Valve 21mm Fit For VW Beetle Golf AUDI A3 A4 1.8T 2.0T 06L109257F

Camshaft Adjuster Control Valve 06L109257F compatible with Audi A3, A4, A5, Q5, VW Golf, Passat, Tiguan, Skoda EA888 MK3 1.8/2.0T engines.

The VVT (Variable Valve Timing) valve regulates intake and exhaust volumes, along with valve opening/closing timing and angles, based on engine operating conditions. This optimization enhances air intake and combustion efficiency.

By controlling oil pressure, the VVT valve adjusts engine intake timing, optimizing the overlap between intake and exhaust systems. This technology reduces fuel consumption while improving overall engine performance.

The engine system controls OCV valve oil passage changes to regulate CVVT advance or lag timing, enabling precise control of valve timing and intake volume for optimal engine performance across various operating conditions.

At low engine speeds requiring high torque, richer mixtures are needed. At higher speeds for power output, leaner mixtures are optimal. The CVVT control valve adapts to these conditions by modifying valve opening timing and intake volume.
