Patent ID: 8333065

Claim:
A power system, comprising: an air induction system; a combustion chamber located downstream of the air induction system; and an exhaust recirculation system, including: a filter configured to receive a flow of exhaust from the combustion chamber, the filter including: a housing having an inlet and an outlet, a tubular filter medium disposed between the inlet and the outlet, the tubular filter medium defining an inner channel, the housing inlet being configured to direct the flow of exhaust to the tubular filter medium, the tubular filter medium being configured to allow the flow of exhaust to pass to the inner channel, the inner channel being configured to direct the flow of exhaust to the housing outlet, and a metal component disposed downstream of the inlet and upstream of the filter medium, the metal component at least partially surrounding the tubular filter medium, the metal component being configured to corrode with sulfuric acid present within the flow of exhaust to form debris, wherein the tubular filter medium is configured to trap the debris to increase a differential pressure between the inlet and the outlet.
