Abstract

A system for determining a regeneration phase of an exhaust gas particulate filter for an internal combustion engine may include a temperature sensor for detecting an elevated exhaust gas temperature, a sensor for detecting the particulate content in the exhaust gas stream exiting from the exhaust gas particulate filter, and a processing device for determining the regeneration phase on the basis of the detected values. A method for determining a regeneration phase of an exhaust gas particulate filter for an internal combustion engine may include detecting an elevated exhaust gas temperature, sampling a signal from a sensor for detecting the particulate content in the exhaust gas stream exiting from the exhaust gas particulate filter, detecting that the particulate content is elevated, and determining the regeneration phase.
