Disclosed is an exhaust reduction device to which a metal foam is applied. The exhaust reduction device, according to the present invention, comprises: an exhaust gas pipe for guiding exhaust gas which is discharged from an internal combustion engine; an oxidized catalyst portion, which is coupled to one end of the exhaust gas pipe so as to communicate with the exhaust gas pipe, and has a hollow shape comprising the metal foam; a diesel fine particle filter portion which encases the oxidized catalyst portion in a radial direction with a distance therebetween and has a hollow shape comprised of the metal foam; a flange, which is coupled to one end of the oxidized catalyst portion and the diesel fine particle filter portion, for inducing the flow of the exhaust gas in a radial direction of the oxidized catalyst portion and the diesel fine particle filter portion; and a heating device for introducing gas at a high temperature into a space that is separated from the oxidized catalyst portion and the diesel fine particle filter portion and provided on an outer circumferential portion of the exhaust gas pipe. |
