ABSTRACT:
An exemplary controller includes one or more processors, memory and control logic to individually control at least one of two exhaust valves of a cylinder of an internal combustion engine to either provide exhaust from the cylinder to a single exhaust turbine or to provide exhaust from the cylinder to two exhaust turbines where the two exhaust valves are mounted in a cylinder head of the internal combustion engine. For example, such a controller may call for operation of one exhaust valve to provide exhaust to a single exhaust turbine and call for operation of two exhaust valves to provide exhaust to two exhaust turbines. Various other exemplary methods, devices, systems, etc., are also disclosed.
