IPC: F01N1/02
Filed: 2011-04-27
Abstract: 일반적으로 내연기관(Internal-Combustion Engine)의 소음기(muffler) 구조는, 내연기관에서 폭발로 발생한 배기가스를 보다 부피가 큰 구조의 실린더 형태의 관(tube)에, 복수의 구멍을 갖는 복수의 판(plate)으로 관을 칸막이 한 구조로 되어 있다. 
따라서, 이러한 구조를 통하여 압축된 배기가스를 팽창시킴과 동시에 작은 구멍을 통과 시키면서 소리의 전달 매체인 공기의 압력과 소리의 진폭을 작게 하여 내연기관에서 발생하는 소음을 감소시킨다고 할 수 있다. 그러나 이러한 구조에서 실시할 수 있는 소음 감소에는 제한이 있다. 
이에 대해, 본 발명은 내연기관에 적용되는 일반적인 구조에서, 폭발 후 폭발음을 전달하는 배기가스의 흐름을 회전 및 불규칙(와류 ; eddy, turbulent flow)하게 하여 배기가스의 압력과 진폭을 보다 더 효과적으로 감소시킬 수 있도록 하는 소음기(배기관) 구조를 갖도록 한다.
