VGT Variable Geometry Turbochargers: Enhancing Engine Performance

Variable geometry turbochargers (VGTs), also referred to as variable-nozzle turbochargers (VNTs), play a crucial role in optimizing engine performance across various operating conditions. These advanced turbochargers are engineered to adjust their effective aspect ratio (A/R ratio) dynamically, ensuring seamless transitions between differing engine speeds.

How VGTs Work

At the heart of a VGT are adjustable vanes positioned inside the turbine housing, nestled between the exhaust inlet and the turbine itself. These innovative vanes control the flow of exhaust gases directed towards the turbine. The adaptability of these vanes allows the turbocharger to maintain an ideal aspect ratio that shifts based on speed, providing significant advantages over traditional fixed-geometry turbochargers.
