ABSTRACT:
An apparatus, system, and method are disclosed for determining a regeneration availability profile for an exhaust gas aftertreatment system. The method, in one embodiment, tracks historical attempts and success to determine the availability of regeneration for the system. In a further embodiment, the method divides the system operation into segments according to desired conditions which affect regeneration, for example the workload of an engine, and tracks separate success ratios for each operating condition. This allows prediction of success of a given regeneration based upon the current operating condition, as well as diagnostics of regeneration problems where an operating condition experiences trouble regenerating when historically it should not.
