Operation: When the engine is under load or at low speeds, the vanes of the VGT are adjusted to open up the exhaust flow. This allows more exhaust gases to flow through the turbocharger, providing more boost pressure and faster spool-up.
Response and Performance: The VGT's ability to adjust the exhaust flow provides faster response and more efficient performance compared to traditional turbochargers. This is because it can provide more boost pressure at low engine speeds, which results in better throttle response and more power.
Advantages: The Variable Geometry Turbocharger provides several advantages, including:
