    摘要： A cordierite honeycomb body is produced by forming a cordierite material including kaoline into a honeycomb shape and sintering it. The kaoline included in the cordierite material is at least partly composed of kaolinite having a Hinckley crystallinity index of 0.5 or more thereby having a less amorphous phase portion in a kaolinite particle. Therefore, when the cordierite material is sintered, the number of micropores generated in the cordierite is decreased due to the less amorphous phase portion in the kaolinite particles. As a result, density of the cordierite is increased without increasing a C.T.E. thereof. Thus, the cordierite honeycomb body has sufficient strength even when thickness of a cell wall thereof is decreased.

    摘要： To prevent the deterioration of catalyst or the damage of a particulate filter caused by the rapid temperature rise of the particulate filter when the abrupt deceleration of an engine occurs, and avoid the deterioration of fuel consumption by depositing a large PM in the particulate filter and regenerating the same at once.A heat-absorbing area 4 is provided by forming a deeply clogged structure at the exhaust gas flowing-out side end of the particular filter 1 disposed in an exhaust pipe 2 of an internal combustion engine E. As the heat-absorbing area has a heat capacity larger than that in the other portions, the combustion heat is absorbed and dispersed even if the rapid chain reaction of PM combustion occurs, whereby it is possible to suppress the temperature rise of the downstream portion of the particulate filter liable to be high in temperature.
