Abstract:
Methods and systems are provided for managing particulate emissions in an engine including a particulate filter and a COsensor downstream of the filter. A COsensor may be used to infer the presence of particulate matter in the exhaust, downstream of the filter. By sensing particulate matter in the post-filter exhaust, filter degradation may be identified.
