Claim 0:
1. A system, comprising:
an exhaust aftertreatment system comprising a particulate filter; and
a controller coupled to an engine and the exhaust aftertreatment system, the controller configured to:
receive a particulate filter regeneration event trigger;
receive information comprising a temperature regarding the particulate filter;
determine the temperature regarding the particulate filter is below a temperature threshold associated with a particulate filter regeneration event; and
responsive to determining the temperature regarding the particulate filter is below the temperature threshold, command the engine to operate in a cylinder deactivation mode, whereby at least one cylinder of a plurality of cylinders of the engine is deactivated according to a firing fraction for the engine of a plurality of firing fractions based on the temperature regarding the particulate filter, the firing fraction defining a number of active cylinders of the engine relative to a total number of cylinders of the engine, wherein each firing fraction of the plurality of firing fractions corresponds to a predetermined temperature value of the particulate filter.
