Abstract: A method for a vehicle comprises responsive to installation of a new exhaust particulate filter, doping fuel with an ash-producing additive, and combusting the doped fuel to produce ash, wherein the ash deposits as an ash coating on the new exhaust particulate filter. In this way, a filtration efficiency of an exhaust particulate filter can be increased quickly as compared to a filter with no deposited ash coating, inexpensively as compared to conventional methods using membranes, and with a lower back pressure drop as compared to conventional methods.

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.
