Muffler for internal combustion engine |
摘要 |
<p>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.</p> |
