Abstract:
A control system for operating vanes of a turbocharger turbine (16T) and for operating a turbine-shunting bypass valve (22) according to a strategy wherein a processor executes an algorithm for selectively unenabling the control system to operate the bypass valve when the control system is operating the vanes to adjust exhaust back-pressure on the engine within a range of effectiveness for the vanes to control the exhaust back-pressure and enabling the control system to operate the bypass valve when the control system has operated the mechanism to a limit of the range of effectiveness.
