Abstract

An apparatus, system, and method are disclosed for determining a regeneration cycle thermal ramp. A thermal ramp module estimates a regeneration cycle thermal ramp. A soot content module estimates a soot content for a filter. In one embodiment, an oxygen content module estimates an oxygen gas concentration for the filter. A thermal profile module calculates a thermal profile for the filter as a function of the soot content and the thermal ramp. The thermal profile module may also include the oxygen content in the thermal profile calculation. A test module modifies the regeneration cycle thermal ramp if the thermal profile exceeds a thermal threshold. In one embodiment, a communication module may communicate a warning if the thermal ramp exceeds a warning threshold.
