Filter regeneration using filter temperature modulation

According to one embodiment, an apparatus for controlling the regeneration of a particulate filter (150) of an internal combustion engine system (100) includes an operating conditions module (250) that is configured to monitor at least one engine system condition (330). The apparatus also includes a...

Beschreibung
Zusammenfassung:	According to one embodiment, an apparatus for controlling the regeneration of a particulate filter (150) of an internal combustion engine system (100) includes an operating conditions module (250) that is configured to monitor at least one engine system condition (330). The apparatus also includes a regeneration module (260) that is configured to trigger a regeneration event if the at least one engine system condition meets a threshold. Further, the apparatus includes a thermal management module (275) that is configured to operate the internal combustion engine system in a thermal management mode for a first time period while a regeneration event is triggered by the regeneration module. Also, the apparatus includes a high NOx module (280) configured to operate the internal combustion engine system in a high NOx mode for a second time period following the first time period while the regeneration event is triggered by the regeneration module.
