    • Provided is a sub-muffler which needs no heat resistant material such as SUS, and which can keep its durability and sound absorbing performance even when the sub-muffler is exposed to various corrosive components in the exhaust gas. At the same time, accomplished is a low-cost manufacture, which is a challenge that sub-mufflers and sound absorbing materials commonly face. Disclosed is a sub-muffler in which a perforated exhaust pipe is arranged, and caps and an out pipe are arranged outside the perforated pipe. Sound absorbing materials are filled in the space between the perforated exhaust pipe, and the caps and the out pipe. The sub-muffler is characterized in that, among the sound absorbing materials, at least part of the sound absorbing material of the perforated pipe side is a basalt fiber for high temperature.
    • 本发明提供一种不需要SUS等耐热材料的副消声器,即使在副消音器暴露于废气中的各种腐蚀性成分的情况下也能够保持其耐久性和吸声性能。 同时,完成了低成本制造,这是子消声器和吸音材料通常面临的挑战。 公开了一种其中布置有穿孔排气管的副消声器,并且在穿孔管的外侧设置有盖和出管。 吸声材料填充在穿孔排气管,盖和出管之间的空间中。 所述副消音器的特征在于,在所述吸声材料中,所述多孔管侧吸声材料的至少一部分为高温玄武岩纤维。
