Regeneration system to regenerate a particulate filter based on code clear diagnostic signal

An exhaust treatment system includes a particulate filter having a filter substrate configured to trap soot contained in exhaust gas. A regeneration system is configured to perform a regeneration operation that regenerates the particulate filter by burning away soot stored in the filter substrate. A...

Beschreibung
Zusammenfassung:	An exhaust treatment system includes a particulate filter having a filter substrate configured to trap soot contained in exhaust gas. A regeneration system is configured to perform a regeneration operation that regenerates the particulate filter by burning away soot stored in the filter substrate. A control module is in electrical communication with the regeneration system to generate a first control signal that initiates the regeneration operation based on a comparison between at least one operating condition of the exhaust treatment system and a threshold value. The control module generates a second control signal in response to detecting at least one diagnostic signal. The second control signal initiates the regeneration operation independently of the comparison.
