Abstract
A particulate filter ash loading prediction method including the steps of determining a maximum average time for the filter; performing a calculation of a running average of time between regenerations of the filter; calculating an end-of-service life ratio of the filter dependent upon the maximum average time and the running average. The method further includes the steps of determining a delta pressure adjustment factor to compensate for ash loading of the filter depending upon the end-of-service life ratio; and comparing the delta pressure adjustment factor to a predetermined maximum delta pressure value, and, if the delta pressure adjustment factor exceeds the predetermined maximum normalized delta pressure adjustment factor, then indicating that a service or replacement of the filter is needed due to the ash loading.
