Abstract
The present disclosure relates to dual fuel internal combustion engines with multiple cylinder banks and/or cylinder subsets, and exhaust aftertreatment systems associated therewith. Systems and methods are disclosed that relate to engine operations involving fuelling control for fuel cutout of one or more of the cylinder banks and/or cylinder subsets in response to a fuel cutout event to increase gaseous fuel substitution on the other cylinder banks and/or cylinder subsets to satisfy the torque request and thermal management conditions of the aftertreatment system.
