1.Precise Regulation of Oil Pressure and Flow Direction
It receives electrical signals from the Engine Control Unit (ECU) and, through the automatic spool movement of its internal center screw structure, precisely controls the flow path and volume of high-pressure engine oil. Based on engine operating conditions (such as speed, load, and water temperature), it accurately delivers oil to the "advance" or "retard" oil chambers of the camshaft phaser, providing a stable power source for valve timing adjustment.
2.Dynamic Adjustment of Camshaft Phase
By controlling oil pressure to drive the rotation of the rotor inside the camshaft phaser, it changes the angle of the camshaft relative to the crankshaft, thereby dynamically adjusting the opening/closing timing and overlap angle of the valves. For example: during low-speed operation, it advances the intake valve opening time to enhance torque output; during high-speed operation, it retards the intake valve closing time to increase air intake and boost power, achieving performance optimization across the entire speed range.
1.OEM-Level Compatibility, No Modification Required for Installation
Developed in strict accordance with Audi and VW’s original equipment (OE) technical specifications, the thread size of the center screw, spool stroke, and interface dimensions are fully matched to the oil passages of the cylinder head in the target vehicle engines. It can directly replace the original parts without additional processing or modification, ensuring high installation efficiency and avoiding issues such as oil leakage and pressure abnormalities caused by compatibility deviations.
2.Center Screw Structure Enhances Control Precision
The "automatic center screw" design ensures more stable spool movement, with oil flow control error limited to within ±5% (better than the ±8% error of some side-mounted spool structures). Even under high-frequency operating conditions (e.g., engine speed above 6000rpm), it can maintain timing adjustment precision, avoiding valve timing deviation caused by spool wobble and reducing the risk of engine knock and power fluctuations.
