Abstract

Systems and methods are described for coordinating the regeneration of a gasoline particulate filter to a time duration when engine output falls below a predetermined load threshold selected to indicate a low power state of the engine. In one particular example, the engine is configured to adjust engine operations to regenerate the particulate filter responsive to engine output falling below a predetermined low power threshold, the regeneration further based on an estimated duration that the output falls continuously below the low power threshold. The system and methods described advantageously allow for either full or partial regeneration events to be performed based on the estimated duration of the engine output below the low power threshold.
