Abstract
A method of adapting operation of a variable geometry turbocharger having a variable position vane mechanism with movable vanes is disclosed. The method includes performing at time Ta vane sweep between open-limit and closed-limit positions to identify an initial range of movement of the mechanism and storing in controller's memory the initial range of movement. The method additionally includes performing at time Ta vane sweep between the open-limit and closed-limit positions to identify a current range of movement of the mechanism and storing in controller's memory the current range of movement. The method also includes comparing the current range with the initial range. Furthermore, the method includes replacing in controller's memory the initial range with the current range if the current range is equal to or greater than a predetermined range to thereby adapt the operation of the turbocharger to the mechanism's wear between Tand T
