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