An exhaust gas purifying system has a honeycomb filter including a porous partition wall having a number of pores arranged so that a plurality of cells communicating between two end faces are formed, and a plugging portion disposed in either of the end faces or inside the cell so as to plug the cell; and a NOx purifying catalyst including a honeycomb catalyst carrier having substantially same shape as the honeycomb filter, and a NOx selective reducing SCR catalyst or a NOx occluding catalyst carried on surface of the partition wall and/or on surface of the pores, wherein the honeycomb filter and the NOx purifying catalytic member are disposed in this order in an exhaust gas flow path where exhaust gas discharged from a diesel engine circulates. n To provide an exhaust gas purifying system which realizes excellent purifying efficiency of NOx contained in exhaust gas discharged from a diesel engine, and small pressure loss, and can be mounted in limited space. |
