Abstract
An internal combustion engine having an exhaust log structure onto which a plurality of turbochargers is connected, each turbocharger having a turbine connected to the exhaust log structure and having an inlet fluidly connectable to a respective one of the plurality of outlet ports, an exhaust valve disposed at a turbine outlet such that the flow of exhaust gas out of the turbine is fluidly blocked, and an actuator associated with the exhaust valve and operating to move the exhaust valve from a closed position to an open position and vice versa. An electronic controller provides a command to the actuator to move the exhaust valve between the open and closed positions and is programmed to selectively open two one or more exhaust valves based on an operating condition of the engine.
