본 고안은 자동차의 엔진으로부터 배기되는 배기가스의 소음(騷音)을 없애주는 마후라(MUFFLER)에 관한 것이다.The present invention relates to a muffler (MUFFLER) to eliminate the noise of the exhaust gas exhausted from the engine of the vehicle.

좀더 자세하게는, 배기가스의 소음을 줄이기 위해 다수의 배기순환실을 형성하여 주는 방법으로 배기소음을 줄일 수 있도록 된 기존의 마후라를 개량하되, 배기가스가 최종적으로 배출되는 최종배기 순환실 내부에 별도의 휠터방치를 착탈가능하게 설치하는 구성으로 배기가스가 최종배기 순환실내부로 유입될때에는 휠터장치를 구성하고 있는 메쉬 지지체와 와이어 패드(WIRE PAD)및 불연성 섬유여과포에 의하여 배기압이 현격하게 떨어져 배기소음이 현저하게 약화됨과 동시에 배기가스에 합유되어 있는 불완전 연소물인 매연을 여과시킬 수 있도록 하므로서 자동차의 배기소음과 매연의 발생을 보다 확실하게 제거하여 대기 환경 오염방지에 이바지할 수 있도록 하는데 목적을 두고 있으며, 또한 마후라의 최종 배기실 부분은 분해 조립이 가능하도록 구성하므로서 휠터장치의 사용 수명이 다했을 경우 마후라 전체를 교차하지 않고 휠터장치만을 간편하게 교체토록 하여 대기환경 오염의 방지효과를 거두면서 자동차 소유자들에게는 경제적인 부담을 줄 일 수 있도록 하는데 다른 목적을 두고 있다.More specifically, in order to reduce the noise of the exhaust gas by modifying the existing exhaust gas to reduce the exhaust noise by forming a plurality of exhaust circulation chamber, the exhaust gas is finally discharged in the final exhaust circulation chamber separately When the exhaust gas flows into the final exhaust circulation chamber, the exhaust pressure drops sharply by the mesh support, the wire pad, and the non-combustible fiber filter cloth. It aims to contribute to the prevention of air pollution by reliably eliminating the exhaust noise and soot emissions of cars by filtering the soot, the incomplete combustion product contained in the exhaust gas, while significantly reducing the noise. In addition, the final exhaust compartment of the Mafura can be disassembled and assembled. When the life span of the filter device is at the end of its life, it is possible to easily replace the filter device without crossing the entire Mafura, thereby preventing air pollution and reducing the economic burden on car owners. have.

일반적으로, 모든 자동차에는 엔진의 배기가스 소음을 줄여주는 마후라가 반드시 설치되어 있으며, 이러한 마후라는 대체로 4개정도의 배기순환실을 형성하여 배기가스가 그 다수의 배기순환실을 거치는 소음이 줄어들도록 한후 배출되도록 하였다.In general, all cars are equipped with a mafura to reduce engine exhaust noise, which generally forms four exhaust circulation chambers to reduce the noise passing through the multiple exhaust circulation chambers. And then discharged.

그러나 상기한 종래의 마후라는 배기가스의 소음을 완벽하게 줄일 수 없을 뿐아니라 배기가스에 함유되어 있는 매연의 제거효과는 기대할 수 없는 결점이 있어 불완전 연소에 의한 매연이 대기로 그대로 방출시키게 되고, 이는 곧 대기환경 오염에 요인이 되어 왔었다.However, the above-described conventional Mahura is not only able to completely reduce the noise of the exhaust gas, but also removes the smoke contained in the exhaust gas. It soon became a factor in air pollution.

한편, 오늘날의 산업 발전은 자동차의 급증시대를 낳고 있는바, 자동차로부터 발생되는 매연의 효과적인 제거방법이 제기되지 않을 경우 세계는 자동차 문화시대에 있어 대기 환경 오염이란 심각한 문제를 해결할 수 없을 것이다.On the other hand, today's industrial development is creating a period of rapid growth of automobiles, and the world will not be able to solve the serious problem of air pollution in the age of automobile culture unless effective methods of removing smoke from automobiles are raised.

따라서 본 고안은 상기와 같은 문제점을 해결하고자 안출한 것으로서, 기존의 자동차 미후라에 배기소음을 없애면서 매연도 함께 제거할 수 있도록 마후라를 개량한 것으로 본 고안을 첨부한 도면에 따라서 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve the above problems, and the present invention will be described in detail according to the accompanying drawings. Same as

마후라(1)의 내부를 4개의 격실이 형성되게 격벽(2),(3),(4)으로 구획한 다음, 엔진(도시없음)의 배기관(5)를 두번째 격실인 제1배기 순환실(6)까지 삽입시키고 제1배기순환실(6)은 정방향 순환관(7)에 의해 세번째 격실인 제2배기 순환실(8)과 상통케하며, 제2배기 순환실(8)은 역방향 순환관(9)에 의하여 첫번째 격실인 제3배기 순환실(10)과 연통되도록 구성되고, 또 제3배기 순환실(10)에는 네번째 격실인 최종 배기순환실(11)로 배기가스를 순환시키는 정방향 최종 순환관(12)을 장착하는 구성으로 배기관(5)으로 배기되는 배기가스를 제1내지 최종 배기순환실을 통과시킨후 배출구(13)로 배출시키도록 구성한 통상의 마후라에 있어서, 상기 최종 배기순환실(11)측 격벽(4)의 정방향 최종 순환관(12) 주위에 조립봉(14)의 용접단(14a)을 용접하고, 배기가스 유입공(15a)이 형성된 선단캡(15)가 조립봉이 나사부(14b)에 나사 조립되는 너트(14c)로 체결, 조립되는 후단캡(16)으로 양단이 복개되며, 내,외측 메쉬 지지체(18a), (18b)와 내,외측 와이어 패드(19a)(19b) 및 불연성 섬유 여과포(20)로 구성된 휠터장치(17)를 최종배기 순환실 내에 장착하여 배기가스의 소음과 매연을 제거할 수 있도록 구성하였으며, 또한 최종 배기순환실(11)후단부는 보울트(21)로 분해 조립이 가능하도록 조립캡(22)을 별도로 구성하여 휠터장치(17)을 착탈할 수 있도록 구성한 것이다.The interior of the Mafura 1 is partitioned into partitions 2, 3, and 4 so that four compartments are formed, and then the exhaust pipe 5 of the engine (not shown) is the first exhaust circulation chamber (the second compartment). 6) and the first exhaust circulation chamber 6 is communicated with the second exhaust circulation chamber 8 which is the third compartment by the forward circulation tube 7, and the second exhaust circulation chamber 8 is the reverse circulation tube. (9) is configured to communicate with the third exhaust circulation chamber 10, which is the first compartment, and in the third exhaust circulation chamber 10, the forward end for circulating the exhaust gas to the final exhaust circulation chamber 11, which is the fourth compartment. In the conventional mafura configured to discharge the exhaust gas exhausted to the exhaust pipe 5 through the first to the final exhaust circulation chamber in a configuration in which the circulation pipe 12 is mounted, the final exhaust circulation The welding end 14a of the assembly rod 14 is welded around the final final circulation pipe 12 of the chamber 11 side partition wall 4, and the exhaust gas inlet 15a is The front end cap 15 is fastened to the rear end cap 16 by fastening and assembling the nut 14c, which is assembled by the assembly rod screwed to the threaded portion 14b, and both ends thereof are covered with inner and outer mesh supports 18a and 18b. The filter device 17 including the inner and outer wire pads 19a and 19b and the non-combustible fiber filter cloth 20 is mounted in the final exhaust circulation chamber to remove noise and smoke from the exhaust gas. The rear end of the circulation chamber 11 is configured to detach the filter device 17 by separately configuring the assembly cap 22 to be disassembled and assembled into the bolt 21.

이와 같이 구성된 본 고안의 작용효과를 설명하면, 종래의 마후라와 같이 엔진으로부터 배출되는 배기가스는 배기관(5)을 통해 두번째 격실인 제1배기순환실(6)로 유입되어, 그 내부를 순환하다가 정방향 순환관(7)으로 해서 제2배기 순환실(8)로 순환, 유입되고, 다시 역방향 순환관(9)을 통해 첫번째 격실인 제3배기순환실(10)로 순환, 유입되었다가 정방향 최종 순환관(12)을 통해서 네번째 격실인 최종 배기순환실(11)로 유입되는 과정을 거치는 동안 배기소음이 약화되도록 하는 것은 종래 마후라의 작용과 마찬가지나, 본 고안에서는 최종배기 순환실(11)내에 휠터장치(17)를 장착하였으므로 배출구(13)로 배출되는 배기소음과 매연이 제거된 상태로 배출되므로 해서 자동차의 소음 공해는 물론이고 매연 공해를 일으킬 염려가 없는 것이다.Referring to the operation and effect of the present invention configured as described above, the exhaust gas discharged from the engine as in the conventional Mafura flows into the first exhaust circulation chamber (6), which is the second compartment through the exhaust pipe (5), It is circulated and introduced into the second exhaust circulation chamber 8 as the forward circulation pipe 7, and then circulated and introduced into the third exhaust circulation chamber 10, which is the first compartment, through the reverse circulation pipe 9, The exhaust noise is attenuated during the process of flowing into the final exhaust circulation chamber 11, which is the fourth compartment through the circulation pipe 12, as in the conventional exhaust gas circulation chamber 11. Since the filter device 17 is installed, the exhaust noise discharged to the outlet 13 and the smoke are discharged in a state of being removed, so that there is no fear of causing noise pollution as well as the noise of the automobile.

즉, 정방향 최종순환관(12)을 통해 최종배기 순환실(11)로 유입되는 배기가스는 휠터장치(17)의 내부로 유입되어 내측 메쉬지지체(18a), 내측와이어 패드(19a), 불연성 섬유여과포(20), 외측와이어 패드(19b), 외측메쉬지지체(18b)를 차례로 통과하는데, 내·외측 와이어 패드는 가는 철사가 공극율이 매우 작게 구성되게 엮어진 상태이므로 배기가스의 충돌 작용을 극대화시켜 소음이 최소로 줄어들게 함과 동시 배기가스에 의해 가열된 상태가 되어 배기가스를 재연소시키는 작용도 하므로 불완전 연소물을 재연소시키는 작용도 하므로서 매연발생을 줄이는 효과를 나타낸 것이며, 내·외측 와이어 패드(19a),(19b)사이에 있는 불연성 섬유 여과포는 통과하는 배기가스에 함유되어 있는 매연을 흡착, 제거하는 작용을 하므로서 훨터장치(17)를 거쳐 나온 배기가스에 매연이 완전 제거된 상태가 되도록 하는 효과가 있으므로서 배출구(13)로 배출되는 배기가스는 소음과 매연이 완전 제거된 상태이므로 자동차의 소음 공해와 매연 공해를 없앨 수 있는 것이다.In other words, the exhaust gas flowing into the final exhaust circulation chamber 11 through the forward final circulation pipe 12 is introduced into the filter apparatus 17 so that the inner mesh support 18a, the inner wire pad 19a, and the non-combustible fiber are introduced. Pass through the filter cloth 20, the outer wire pad (19b), the outer mesh support (18b) in order, the inner and outer wire pads are woven to form a very small porosity so as to maximize the impact of the exhaust gas The noise is reduced to a minimum, and the gas is heated by the exhaust gas, and thus, the exhaust gas is reburned. Thus, the combustion effect of the incomplete combustion products is also reduced. The non-combustible fiber filter cloth between 19a) and 19b acts to adsorb and remove the soot contained in the exhaust gas passing through the exhaust gas from the blower apparatus 17. Kite exhaust gas discharged to the document discharge port 13, so that the effect of the complete elimination of the state will be eliminated in the noise pollution, and pollution of the exhaust because of noise and fumes fully removed car.

이와 같은 본 고안은 기존의 마후라의 최종 배기 순환실을 개선하여 훨터장치를 착탈 가능하게 부착하는 수단으로 자동차의 배기소음과 공해를 없앨 수 있으며, 또한 휠터장치의 사용 수명이 다했을 경우에는 조립캡(22)를 분리한 다음 너트(14c)를 나사 분해하는 해체 수단으로 휠터장치(17)를 교체할 수 있으므로서 대기환경 오염 방지에 크게 이바지할 수 있는 실용적인 고안이 것이다.The present invention improves the existing exhaust circulation chamber of the existing Mafura and removes the exhaust noise and pollution of the vehicle as a means of attaching the detachable apparatus to the vehicle. Since the filter device 17 can be replaced by a dismantling means of disassembling the screw 22 and then disassembling the nut 14c, it is a practical design that can greatly contribute to the prevention of air pollution.
