Abstract
Various methods and systems are provided for dynamically assigning cylinders to cylinder sets in engines having two or more cylinder banks, wherein each cylinder bank is fed intake air by a separate intake manifold, and wherein each cylinder bank includes a separate exhaust manifold. In one example, the current disclosure teaches comparing engine operating conditions against a plurality of predetermined override conditions, and responding to the engine operating conditions matching a predetermined override condition of the plurality of predetermined override conditions by reassigning at least a first cylinder of a first cylinder bank from a first cylinder set to a second cylinder set, and adjusting an operating parameter of the second cylinder set and first cylinder set based on the override condition. In this way, cylinders may be dynamically assigned to cylinder sets based, from a default cylinder set, based on occurrence of predetermined override conditions.
