Abstract
A method for determining the service interval of a particulate filter including the steps of determining a normalized current pressure differential across the particulate filter and determining a normalized pressure differential across the particulate filter for clean conditions. The clean pressure normalized pressure differential is subtracted from the current differential and divided by the time between regeneration to determine a current factor. A maximum factor is predetermined and compared to the current factor to determine service life for the particulate filter.
