<p>PURPOSE:To improve the regeneration rate and to make regeneration more complete by imparting permittivity to the periphery of a ceramic corrugated honeycomb structure or to the several layers from the periphery and promoting the incineration of the periphery or its vicinity by microwave irradiation. CONSTITUTION:The ceramic sheet of which a corrugated sheet is adhered to another flat sheet is laminated or rolled up and integrated by calcination. Plugs 3 and 4 are alternately inserted into the two adjacent ends of the ceramic corrugated honeycomb structure thus obtained, and the periphery or the several layers from the periphery are covered with a high-permittivity part 5 (e.g. fibrous ceramic contg. titanium oxide). Namely, the particulates of the exhaust gas filter are incinerated by microwave irradiation, the incineration is promoted especially at the periphery or its vicinity, the regeneration rate is improved, and the regeneration is made more complete.</p> |
