Systems and methods for particulate filter regeneration with cylinder deactivation

A method comprising:

• receiving a particulate filter regeneration event trigger regarding a system comprising an engine coupled to an exhaust aftertreatment system, the exhaust aftertreatment system comprising a particulate filter;
• receiving information associated with the particulate filter, the information comprising a temperature regarding the particulate filter;
• determining the temperature regarding the particulate filter is below a temperature threshold associated with a particulate filter regeneration event;
• and
• responsive to determining that the temperature regarding the particulate filter is below the temperature threshold, commanding the engine to operate in a cylinder deactivation mode as part of a particulate filter regeneration event 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.

A system structured to regenerate or assist with regenerating a particulate filter, the system comprising:

• a processor;
• and
• a memory coupled to the processor, the memory storing instructions therein that, when executed by the processor, cause operations comprising:
• receiving a particulate filter regeneration event trigger regarding a system comprising an engine coupled to an exhaust aftertreatment system, the exhaust aftertreatment system comprising a particulate filter;
• receiving information, the information comprising a temperature regarding the particulate filter;
• determining the temperature regarding the particulate filter is below a temperature threshold associated with a particulate filter regeneration event for the particulate filter;
• and
• responsive to determining that the temperature regarding the particulate filter is below the temperature threshold, commanding the engine to operate in a cylinder deactivation mode as part of a particulate filter regeneration event 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.
