Abstract:
An exhaust gas purifying apparatus includes a primary diesel particulate filter provided in an exhaust line of a diesel engine, a secondary exhaust line branched from the exhaust line from an upstream side of the primary diesel particulate filter, and a secondary diesel particulate filter provided in the secondary exhaust line. The secondary diesel particulate filter has a soot storage capacity smaller than the soot storage capacity of the primary diesel particulate filter. The apparatus further includes a differential pressure measuring part for measuring a differential pressure between an inlet and an outlet of the secondary diesel particulate filter.
