<P>PROBLEM TO BE SOLVED: To provide a wall-flow type filter for cleaning exhaust gas which can burn and remove particulates in the pores in a partition wall. <P>SOLUTION: The wall-flow type filter for cleaning exhaust gas has many cells formed in the exhaust gas flow direction. The cells are plugged alternately at the exhaust gas inlet end. The cells plugged at the inlet end are opened at the exhaust gas outlet end, and the cells opened at the inlet end are plugged at the outlet end. Pores having an average diameter of 25-40 μm are formed in the partition wall between the cells, and a catalyst (16) is carried in the pores. <P>COPYRIGHT: (C)2003,JPO |
