Abstract
In accordance with exemplary embodiments, the present invention relates to systems and methods for regeneration of a filter, particularly a diesel particulate filter. In one exemplary embodiment, a method of regeneration of a particulate matter filter is provided. The method includes providing a heat source for regeneration of a particulate matter filter. The heat source is disposed proximate or upstream from the particulate matter filter. The method also includes activating the heat source to generate a first temperature profile of the heat source, the first temperature profile including a first temperature average. The method further includes increasing the temperature of the heat source to generate a second temperature profile of the heat source, the second temperature profile including a second temperature average, wherein the second temperature average is greater than the first temperature average.
