摘要: A honeycomb filter includes a pillar shape honeycomb structure that has a plurality of cells 28, which are arranged in a honeycomb shape and partitioned by cell walls 27, and a plug 30 that seals either one of open ends of each cell 28. In the honeycomb filter, the plug 30 has a clad 30a that occupies a peripheral region near the cell wall 27 and a core 30b that occupies a central region including the central axis of the cell 28. The Young's modulus of the clad 30a differs from the Young's modulus of the core 30b.

摘要: The invention provides a muffler (10) for internal combustion engine having excellent durability (resistance to scattering) even when being exposed to a high-temperature exhaust gas and capable of maintaining high sound absorption coefficient over a long period.
Such a muffler (10) comprises a metal tube (12) provided with a plurality of small holes (11), an inorganic fiber sound absorbing material (14) arranged on the outer periphery thereof and a metal shell (13) covering the outside of the sound absorbing material (14), in which a scattering prevention member (18) is disposed between the metal tube (12) and the sound absorbing material. The sound absorbing material (14) is a laminated structure of crystalline alumina fiber mat (15) and glass fiber mat (17). As the scattering prevention member (18), there is used a stainless woven wire cloth, a woven fabric made from inorganic fiber and a metal foil.摘要翻译: 本发明提供即使暴露在高温废气中并能够长时间保持高吸音系数的耐久性(耐散射性)的内燃机消声器(10)。 这种消音器(10)包括设置有多个小孔(11)的金属管(12),布置在其外周上的无机纤维吸声材料(14)和覆盖外部的金属壳(13) 吸音材料(14),其中散射防止构件(18)设置在金属管(12)和吸声材料之间。 吸声材料(14)是结晶氧化铝纤维毡(15)和玻璃纤维垫(17)的叠层结构。 作为防散射构件(18),使用不锈钢编织布,由无机纤维制成的织物和金属箔。
