An adsorbent (42) may be positively regenerated by a technique to remove adhered materials such as soot adhered to the adsorbent (42) so that the durability of the adsorbent (42) is enhanced. To meet this, an exhaust gas purifying apparatus for an internal combustion engine, comprises a path switcher (40) for introducing exhaust gas from the internal combustion engine into at least one of a first exhaust gas path (A) and a second exhaust gas path(B) branched downstream of catalysts (3a,3b), an adsorbent (42) disposed in the first exhaust gas path (A) for adsorbing unburnt gas components contained in the exhaust gas, a recirculating device (5,VSV1)for recirculating the unburnt gas components separated from the adsorbent (42) to an upstream side of the catalysts (3a,3b), and a temperature elevator for elevating a temperature of the adsorbent (42) after the unburnt gas components separated from the adsorbent (42) has been recirculated by the recirculating device (5,VSV1). <IMAGE> <IMAGE> |
