Abstract

An active regeneration method for a gasoline particulate filter includes determining if a particulate filter soot load level is greater than a predetermined soot load level threshold and, if so, determining if the particulate filter's temperature is greater than a predetermined burn off temperature threshold. A particulate filter heating phase is initiated when the particulate filter's temperature is not greater than a predetermined burn off temperature threshold and a soot burning phase is started when the particulate filter's temperature is greater than a predetermined burn off temperature threshold.
