Variable Nozzle Turbine(VNT):-



With this system, the turbine on the intake side has movable guide vanes that change position to provide optimum flow conditions and a high turbine efficiency rating, throughout the engine speed range. This permits high boost pressure from low engine speeds, and thus a flatter torque curve and higher power output.

The movable guide vanes are controlled by the engine
