Beschreibung
Zusammenfassung:	A method for determining the service life for a particulate filter (36) receiving products of combustion from and filter soot particles from an air breathing, fuel consuming internal combustion engine (12) including the steps of: determining normalized current pressure differential across the particulate filter (36); determining the normalized pressure differential across the particulate filter (36) for clean conditions; subtracting the clean pressure differential across the particulate filter (36) from the current pressure differential across the particulate filter (36) and dividing the time between regeneration to determine a current factor; and determining a maximum factor and comparing the current factor to the maximum factor for determining service life.
