Variable-geometry turbochargers (VGTs), occasionally known as variable-nozzle turbochargers (VNTs), are a type of turbochargers, usually designed to allow the effective aspect ratio (A/R ratio) of the turbocharger to be altered as conditions change.

Variable geometry turbos or VGTs are here to stay. They are ECM or computer controlled and use no waste gate. Used by most manufacturers (Cumming, Carterpillar & Navistar), knowledge of their...

In a nutshell, variable geometry turbochargers (VGT) are combining the benefits of a small A/R ratio and a large A/R ratio into one unit, bringing together the advantages of both types. Variable geometry turbochargers means variable A/R ratios.

Jul 31, 2014 · Vehicles equipped with Variable Geometry Turbochargers (VGT) offer drastically increased boost pressure over a much wider rpm range. Graphically, the rpm vs. boost …

May 1, 2017 · VGT technology (also known as VNT-Variable Nozzle Turbocharger) is employed in a huge range of applications, such as in commercial on- and off-highway, passenger, marine and rail internal combustion engine applications.

Apr 8, 2022 · The video shows us inside a typical moving-vane variable geometry turbocharger. This consists of a set of vanes that sit around the exhaust turbine, with their angle controlled by an actuator.

Aug 16, 2006 · Variable Turbine Geometry technology is the next generation in turbocharger technology where the turbo uses variable vanes to control exhaust flow against the turbine blades.

Jun 20, 2024 · VGT is the abbreviation of English Variable geometry turbocharger, which solves the balance between turbo lag and boost energy. It brings smoothness, low fuel consumption, low noise and excellent high-speed power to the engine.

Nov 12, 2024 · A Variable Turbine Geometry turbocharger is also known as a variable geometry turbocharger (VGT), or a Variable Nozzle Turbine (VNT). A turbocharger equipped with Variable Turbine Geometry has little movable vanes which can direct exhaust flow onto the turbine blades.

Jan 28, 2015 · How variable geometry turbochargers (VGT), or variable nozzle turbochargers (VNT) work. Variable geometry turbos use vanes to alter the air flow path of the exhaust gases to maximize boost across the entire rev range.
