Abstract:
A method of controlling a turbocharger for an engine and a control system for the same includes a variable nozzle turbine control module operating a variable nozzle turbine of a high pressure turbocharger closed loop in a first load-engine speed region. The system also includes a high pressure turbine bypass valve control module operating a high pressure turbine bypass valve in a closed position in a first load-engine speed region. The variable nozzle turbine control module operates a variable nozzle turbine closed loop in a second load-engine speed region between the first load-speed region and a third load speed region. The high pressure turbine bypass valve module operates the high pressure turbine bypass valve in a transient region in the second load-engine speed region. The variable nozzle turbine control module operates the variable nozzle turbine open loop. The high pressure turbine bypass valve control module operates a high pressure turbine bypass valve in an open position in a third load-engine speed region.
