| 内容： | To obtain a honeycomb filter in which particulates are burned easily by a catalytic substance and are hardly accumulated, the damage or erosion of which is avoided and the pressure loss of which is stabilized over a long period of time and is hardly increased. ! The ceramic honeycomb filter comprises a porous ceramic honeycomb structure having partition walls defining flow paths, and plugs disposed inside the flow paths such that exhaust gas passes through pores of the partition walls. The catalytic substance is deposited at least partially on the partition walls and the plugs. At least one of plugs on the exhaust gas inlet side is disposed in a position separate from the end face of the corresponding flow path on the exhaust gas inlet side. ! (C)2007,JPO&INPIT |
