VNT Turbochargers are commonly used in most diesel passenger cars and commercial vans. The VNT stands for Variable Nozzle Turbine, which means that the internal technology of the turbocharger uses variable vanes to control the exhaust flow against the turbine blades. These types of turbo’s are also sometimes referred to as Variable-Geometry Turbochargers or Variable-Turbine Geometry Turbochargers .These turbo’s are highly efficient and very complex, as variable vanes act as a sophisticated Engine Management System used for minimising turbo lag which improves throttle responsiveness, particularly at low engine speeds. This is done by altering the direction and speed in which the gasses impact with the turbine wheel.
This type of technology is used by many turbocharger manufacturers including; BorgWarner, Holset, IHI, Cummins and Mitsibushi but it is most commonly associated Garrett, the world's leading turbocharger manufacturer, who's method of incorporating "a ring of small movable vanes around the turbine wheel" is featured in millions of passenger cars and vans around the world today.
