Abstract
The present disclosure relates to engines with multiple cylinder banks and associated exhaust aftertreatment systems. Systems and methods are disclosed that relate to engine operations involving fuelling and throttle control for thermal management of the aftertreatment system of one cylinder bank while the other cylinder bank or banks are fuelled to satisfy a portion of the torque request to the engine that is not satisfied by the thermally managed cylinder bank.
