Abstract
A particulate filter ash loading prediction method including the steps of determining a maximum average lifetime for the particulate filter; performing a calculation of a running average of time between regenerations of the particulate filter; calculating an end-of-service-life ratio of the particulate filter dependent upon the maximum average lifetime and the running average; and comparing the end-of-service-life ratio to a predetermined minimum end-of-service-life ratio. If the end-of-service-life ratio is equal to or less than the minimum end-of-service-life ratio then indicating that at least one of service and replacement of the particulate filter is needed due to ash loading.
