" a variable area nozzle turbine (VATN) employs a set of vanes that can change position to alter the exhaust gas velocity as it enters the turbine. this permits the turbine to behave like a small A/R housing at low flow rates, and a high A/R housing at the upper end of the rpm range, with a smooth transition between the two. The durability of early VATN assemblies was reportedly poor, but manufacturers have since greatly impoed the reliability of the units."
