오토바이 머플러 {muffler for motorcycle}Motorcycle muffler {muffler for motorcycle}

본 고안은 오토바이 머플러에 관한 것으로 배기력을 향상시켜 부압을 감소시키고 소음효과를 높히고 촉매를 장치하여 배기가스를 감소시킬 수 있게 한 것이다.The present invention relates to a motorcycle muffler to improve the exhaust force to reduce the negative pressure, increase the noise effect and to reduce the exhaust gas by installing a catalyst.

종래의 오토바이 머플러는 원통으로 되어 내관과 외관사이에 흡음재를 충진하고 내관에 다수의 구멍을 뚫어 소음작용을 하도록 구성하고 있으나 배기가스가 내관을 지나 배출되는 경로가 협소하여 배기력이 순탄하지 못하고 배기가스를 감소시키는 촉매가 없어서 배기가스가 외부로 많이 방출되는 문제가 있었다.Conventional motorcycle mufflers are made of cylindrical cylinders to fill sound absorbing material between the inner tube and the exterior, and to make noise by drilling a plurality of holes in the inner tube, but the exhaust gas flows through the inner tube so narrow that the exhaust force is not smooth. There is a problem that the exhaust gas is emitted to the outside because there is no catalyst to reduce the gas.

본 고안은 배기력을 증대시켜 소음효과를 높이고 촉매를 장치하여 미연소가스에 의한 배기가스 감소를 달성할 수 있게 구성한 것이다.The present invention is designed to increase the exhaust power to increase the noise effect and to reduce the exhaust gas by the unburned gas by installing a catalyst.

본 고안은 외통과 내통사이에 흡음재가 내장되고 내통입구에 연소용 촉매를 장치하여 배기가스를 감소시키고 내통배출부에 직경이 큰 배기관 직경이 작은 배기관을 두갈래로 형성시킨 배기관을 장치하여 배출력을 높이면서 출구에 소음기를 장치하여 소음효과를 높힌 것이다.The present invention incorporates a sound absorbing material between the outer cylinder and the inner cylinder and reduces the exhaust gas by installing a catalyst for combustion at the inlet of the inner cylinder, and the exhaust pipe is equipped with an exhaust pipe having a double exhaust pipe having a large diameter of the exhaust pipe in the inner cylinder discharge portion. Increase the noise effect by installing a silencer at the exit.

이와 같이 된 본 고안은 내통(2)와 외통(1)사이에 흡음재(6)가 내장되어 있고 내통은 주벽에 구멍(2a)이 형성된 관체로 되어 외면에 망관체(2b)가 피복되어 있으므로 내통속으로 통과되는 배기가스의 소음을 흡음재가 흡입하여 완화시키는 효과가 있고 배기가스가 유입되는 입구측에 연소촉진용촉매(3)가 장치되어 미연소가스를 한번 더 연소시켜 주므로 배기가스가 외부로 방출되는 것을 감소시키게 되며 배출부가 직경이 큰 배기관(4a)과 직경이 적은 배기관(4b)으로 나누어져 배출되는 공기를 분배하므로 배출력이 증대되어 배기압을 낮추게 되는 이점이 있고 소음효과를 향상시키게 된다.
특히 본 고안의 외통은 스텐레스스틸, 티타늄, 철, 알루미늄, 탄소섬유 직물지 중에서 선택할 수 있고 배기관은 알루미늄제 분할체로 성형되어 결합되는 구성체이므로 제작이 용이하고 내면이 매끄럽게 배기관 형상이 최적화되어 성능을 높여주는 장점이 있으며 배기관(4a)(4b)은 보호관(5a)(5b)에 의하여 보호되어 외부로 돌출되지 않으므로 손상의 위험이 없고 분할체를 결합한 흔적이 외부에 보이지 않도록 되어 상품가치가 높아지는 장점이 있다.According to the present invention, the sound absorbing material 6 is embedded between the inner cylinder 2 and the outer cylinder 1, and the inner cylinder is a tubular body having a hole 2a formed in the circumferential wall, and the outer tubular body 2b is coated on the outer surface. The sound absorbing material absorbs and reduces the noise of exhaust gas passing through the barrel, and the combustion-promoting catalyst (3) is installed at the inlet side of the exhaust gas so that the unburned gas is burned once more. Since the discharge part is divided into a large diameter exhaust pipe 4a and a small diameter exhaust pipe 4b to distribute the discharged air, the discharge power is increased to lower the exhaust pressure and improve the noise effect. do.
In particular, the outer cylinder of the present invention can be selected from stainless steel, titanium, iron, aluminum, and carbon fiber fabric paper, and the exhaust pipe is formed by combining with aluminum divider, so that it is easy to manufacture and the exhaust pipe shape is optimized to smoothly improve the performance. The exhaust pipes 4a and 4b are protected by the protective pipes 5a and 5b so that they do not protrude to the outside, so there is no risk of damage and the traces of the combined partitions are not visible to the outside, thereby increasing the value of the product. .
