Gasoline particulate filter regeneration strategy

The method determines whether soot loading of a gas particulate filter (GPF) requires regeneration. If it does, the temperature of the GPF is read to determine whether it is sufficiently high to achieve particulate (soot) burning. If it is not, an engine control module is commanded to adjust variables such as spark timing, fuel injection timing and valve timing. If the temperature of the particulate filter is sufficiently high that regeneration can occur, other variables may be adjusted such as leaning the air / fuel mixture, retarding the spark timing, the fuel injection and valve timing. Because the latter adjustments may limit or reduce either engine speed or power, messages in a message center are provided indicating, first, that the driver should continue driving for GPF regeneration and, subsequently, under certain conditions, that the engine power has been reduced. Operation of the motor vehicle proceeds until, based upon sensed conditions or pre-determined experimental or empirical data, the filter has been regenerated.
