Abstract:
An exhaust gas purifying apparatus is comprised of a plurality of exhaust gas passages, and a filter body 3 installed in the exhaust gas passages. The exhaust gas passage contains a filter-conducting portion 100 of conducting the exhaust gas to the filter body 3, and a filter-bypassing portion 200 of bypassing the filter-conducting portion 100 by branching out to an exhaust gas passage adjacent from the filter-conducting portion 100. When PMs are deposited on the filter-conducting portion 100 and an exhaust gas pressure loss is increased, the exhaust gas is branched out from the filter-bypassing portion 200 to flow.
