Abstract
A method for controlling and engine system with a plurality of turbochargers. At least one of the plurality of turbochargers has a turbine valve, a compressor valve, and actuators operable to change the position of the turbine valve. The method comprises controlling the actuator based on the presence of a transient event or a steady state event. During a transient event an engine control module can control the actuators to change the turbine valve to opened and closed positions and the turbine valve to a closed position based on the comparison between a corrected mass flow per turbocharger to a mass flow threshold.
