본 고안은 자동차의 배기계통에서 유해성분의 정화장치인 컨버어터의 효유를 향상시키기 위해 컨버어터의 입구측에 배기가스 확산판을 설치한 자동차의 배기가스 확산판이 설치된 컨버어터에 관한 것이다.The present invention relates to a converter provided with an exhaust gas diffusion plate of a vehicle provided with an exhaust gas diffusion plate on the inlet side of the converter in order to improve the efficiency of the converter, a purification device for harmful components in the exhaust system of the vehicle.
일반적으로 차체로부터 배기가스중의 유해성분을 정화하는 수단으로서 배기가스 정화장치는 배기관의 중간지점에 설치된다.In general, an exhaust gas purification device is installed at an intermediate point of an exhaust pipe as a means for purifying harmful components in exhaust gas from a vehicle body.
제1도는 상기한 배기가스 정화장치의 설치상태를 개략적으로 도시한 자동차 배기계통을 도시한 것으로, 미도시된 엔진에 부착된 배기 매니폴드에 배기관(1)의 선단이 연결되고 배기관(1)의 선단이 연결되고, 배기관(1)의 중간에는 배기가스중의 유해한 성분을 촉매로 변환시키는 촉매 컨버어터(10; 혹은 삼원촉매장치라고도 하며, 이하 '컨버어터'라고 약칭한다)가 설치되며, 상기 컨버어터(10)의 후측으로는 보조소음기(20) 및 주 소음기(22)가 부착되어 엔진으로부터 배출되는 배기가스의 온도와 압력을 낮추어 배기소음을 저하시키는 작용을 하게 된다.FIG. 1 shows an automobile exhaust system schematically showing the installation state of the exhaust gas purifying apparatus, wherein an end of the exhaust pipe 1 is connected to an exhaust manifold attached to an engine not shown, and The front end is connected, and in the middle of the exhaust pipe 1, a catalytic converter 10 (also referred to as a three-way catalyst device, hereinafter referred to as a "converter") is installed, which converts harmful components in exhaust gas into a catalyst. An auxiliary silencer 20 and a main silencer 22 are attached to the rear side of the converter 10 to lower the temperature and pressure of the exhaust gas discharged from the engine, thereby reducing exhaust noise.
한편, 본 고안과 관련한 컨버어터(10)는 제2도에 도시한 바와 같이 케이스(11)내의 격자상의 알루미나(12)에 촉매작용을 하는 금속인 백금 + 로듐 또는 백금 + 로듐 + 파라듐을 부착시켜 배기가스중에 함유된 일산화 탄소(C0), 탄솨수도(HC) 및 질소산화물(NOx)등을 무해한 이산화탄소(CO2) 및 물(H2O)등으로 변환시키는 장치로서, 입구측(13)을 통하여 유입된 배기가스중의 무해성분이 격자상의 알루미나(12)를 거치면서 이 알루미나(13)에 부착된 촉매의 작용을 받아 무해한 성분으로 변환되어 배출측(15)으로 배출되어지도록 구성되어 있었다.Meanwhile, the converter 10 according to the present invention attaches platinum + rhodium or platinum + rhodium + palladium, which are metals catalyzing the lattice alumina 12 in the case 11, as shown in FIG. To convert carbon monoxide (C0), carbon monoxide (HC) and nitrogen oxides (NOx) contained in the exhaust gas into harmless carbon dioxide (CO2) and water (H2O), etc. The harmless components in the exhaust gas were subjected to the action of the catalyst attached to the alumina 13 while passing through the lattice-shaped alumina 12, and converted into harmless components and discharged to the discharge side 15.
한편, 상기한 종래의 컨버어터는 매니폴드에 연결된 배기관(1)의 플랜지부(2)에 그 입구측(13)의 플랜지부(14)가 결합되고, 상기 컨버어터(10)의 입구측(13)은 내부로 확장된 형상을 갖으며, 컨버어터(10)의 내부는 격자상의 알루미나(12)가 배치되어 있었기 때문에 엔진으로부터 배출되는 배기가스가 앞측의 배기관(1)을 통하여 컨버어터(10)로 진입하게 될 때, 배출가스는 자체의 배출속도에 의한 직진성으로 컨버어터(10)내부의 격자상의 알루미나(12)에 전면적으로 확산되지 못하고 배기가스의 대부분은 상기 알루미나(12)의 중간부만을 집중적으로 통과하게 됨으로써 중간부의 알루미나(12)가 배기가스의 열에 의해 열화되고 배기가스와 알루미나(12)의 접촉면적이 국부적으로 집중되어 촉매작용의 효율의 낮아지게 되는 문제점이 있었다.On the other hand, in the conventional converter, the flange portion 14 of the inlet side 13 is coupled to the flange portion 2 of the exhaust pipe 1 connected to the manifold, and the inlet side of the converter 10 ( 13 has a shape extending inwardly, and since the alumina 12 having a lattice shape is disposed in the inside of the converter 10, exhaust gas discharged from the engine is transferred to the converter 10 through the exhaust pipe 1 on the front side. When entering the exhaust gas, the exhaust gas does not spread all over the lattice-like alumina 12 inside the converter 10 due to its direct velocity, and most of the exhaust gas is in the middle portion of the alumina 12. By intensively passing through the bay, the alumina 12 in the middle part is deteriorated by the heat of the exhaust gas, and the contact area between the exhaust gas and the alumina 12 is locally concentrated, thereby lowering the efficiency of the catalytic action.
본 고안은 상기한 종래의 제반 문제점을 감안하여 안출된 것으로, 본 고안의 목적은 엔진으로부터 배출되는 배기가스와 컨버어터의 촉매가 부착된 알루미나와의 접촉면적을 넓혀 촉매작용을 극대화시킴으로써 배기가스중에 함유된 유해성분의 정화효율을 향상시키도록 하는 수단을 제공하는데 있는 것이다.The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to maximize the catalytic action by expanding the contact area between the exhaust gas emitted from the engine and the alumina to which the catalyst of the converter is attached. It is to provide a means for improving the purification efficiency of the harmful components contained.
이와 같은 목적을 달성하기 위하여 본 고안은 배기관의 중간에 설치된 컨버어터의 입구측에 엔진으로부터 배출되는 배기가스가 컨버어터 내부의 전방향으로 확산되도록 하는 배기가스 확산판을 설치한 것으로 이하 첨부된 도면에 의하여 본 고안의 구성 및 작용효과를 상세히 설명하기로 한다.In order to achieve the above object, the present invention provides an exhaust gas diffusion plate for discharging exhaust gas from the engine in all directions inside the converter at the inlet side of the converter installed in the middle of the exhaust pipe.

An outer flow passage 37 is formed by the ribs 35 between the pipe portions 33 and each having an open shape.
상기 플랜지(32)는 제4도에 도시한 바와 같이, 배기관(1)의 플랜지부(2)와 동일한 크기 및 형상으로 형성하여 배기관(1)의 플랜지부(2)와 컨버어터(10)의 입구측(13)에 형성된 플랜지부(14)사이에 끼워 결합시키되 확산판(30)의 외측관부(33)를 컨버어터(10)의 내부로 삽입시킨 상태에서 보울트(38)를 체결하여 상호 기밀을 유지하도록 견고하게 결합시킨다.As shown in FIG. 4, the flange 32 is formed in the same size and shape as the flange portion 2 of the exhaust pipe 1, so that the flange portion 2 and the converter 10 of the exhaust pipe 1 are formed. The flanges 14 formed on the inlet side 13 are fitted to each other, and the bolt 38 is fastened while the outer tube portion 33 of the diffusion plate 30 is inserted into the converter 10. Combine firmly to maintain.
이와 같이 결합된 본 고안의 배기가스 확산판(30)은 제5도에 도시한 바와 같이, 엔진으로부터 배출된 배기가스가 배기관(1)을 통하여 컨버어터(10)로 진입하게 될 때, 상기 컨버어터(10)의 입구측(13)에 설치된 배기가스 확산판(30)을 거치게 되며, 이 확산판(30)에서는 배기관(1)으로부터 공급되는 배기가스가 확산판(30)내부의 내측관부(34)에 형성된 중심유로(36)를 거쳐 컨버어터(10)내부에 설치된 격자형 알루미나(12)의 중간부분으로 공급되어짐과 동시에, 배기가스는 확산판(30)의 내측관부(34)와 외측관부(33)사이에 형성된 바깥유로(37)를 거치게 되면서 진행방향이 외측으로 확산되어져 컨버어터(10)의 내부로 진입하게 되는 것이다.The exhaust gas diffusion plate 30 of the present invention coupled as described above, when the exhaust gas discharged from the engine enters the converter 10 through the exhaust pipe 1, as shown in FIG. Passing through the exhaust gas diffusion plate 30 provided on the inlet side 13 of the adapter 10, the exhaust gas supplied from the exhaust pipe (1) is the inner tube portion (inside) of the diffusion plate (30) The exhaust gas is supplied to the middle portion of the lattice-shaped alumina 12 installed inside the converter 10 via the central flow passage 36 formed at 34, and exhaust gas is discharged from the inner tube portion 34 and the outer portion of the diffusion plate 30. Passing through the outer flow path 37 formed between the tube portion 33 is the progress direction is diffused to the outside to enter the interior of the converter (10).
이처럼 본 고안의 확산판(30)은 엔진으로부터 배출된 배기가스가 배기관(1)을 통하여 컨버어터(10)로 공급되어질 때 배기가스의 배출속도에 의한 직선적인 진행방향을 컨버어터(10)의 내부로 넓게 펴지도록 함으로써 배기가스가 컨버어터(10)내부에 설치된 격자상의 알루미나(12)에 넓게 골고루 접촉되도록 함으로써 배기가스중의 유해성분이 상기 알루미나(12)에 부착된 촉매와 접촉하여 산화, 환원작용을 함으로써 무해한 성분으로 변환되는 작용을 활성화 시키게 되는 것이다.As described above, the diffusion plate 30 of the present invention has a linear traveling direction by the discharge speed of the exhaust gas when the exhaust gas discharged from the engine is supplied to the converter 10 through the exhaust pipe 1. By spreading widely inside, the exhaust gas is widely and evenly contacted with the lattice-shaped alumina 12 installed inside the converter 10, so that harmful components in the exhaust gas come into contact with the catalyst attached to the alumina 12 to be oxidized and reduced. By acting, it activates the action of transforming into harmless components.
이상 설명한 바와 같이 본 고안은 컨버어터의 입구측에 엔진으로부터 배출되는 배기가스가 컨버어터 내부의 전 방향으로 확산되도록 하는 배기가스 확산판을 설치한 것으로, 본 고안에 의하면 엔진으로부터 배출되는 배기가스가 확산판에 의하여 넓게 확산되면서 컨버어터의 촉매가 부착된 알루미나와 골고루 접촉하게 됨으로써 알루미나에 부착된 촉매작용이 극대화 되는 것이며, 이에 따라 배기가스중의 유해성분이 효과적으로 산화, 환원작용을 하게 되어 무해성분으로 변환될 수 있는 것이고, 이는 결국 컨버어터의 정화효율을 향상시켜 대기중으로 배출되는 배기가스중의 유해성분유율을 낮춰주게 됨으로써 대기오염문제를 극복하는 데 일조할 수 있는 효과를 갖게 되는 것임과 아울러 확산판에 의하여 배기가스가 격자형의 알루미나에 전체적으로 확산됨으로써 종래 배기가스가 상기 알루미나의 중앙부에 집중되어 중앙부분이 배기가스의 열에 의하여 열화되는 것을 방지하여 컨버어터의 수명을 연장시킬 수 있는 효과도 갖는다.As described above, the present invention is provided with an exhaust gas diffusion plate which allows exhaust gas discharged from the engine to be diffused in all directions inside the converter at the inlet side of the converter. As it is widely diffused by the diffusion plate, the catalytic converter attached to the alumina is maximized by uniformly contacting with the alumina to which the catalyst of the converter is attached. It can be converted, which in turn improves the purification efficiency of the converter, thereby lowering the harmful component flow rate in the exhaust gas discharged into the atmosphere, which will contribute to overcoming the air pollution problem. The plate allows the exhaust gas to flow to the lattice-like alumina as a whole. By diffusion also has a conventional exhaust gas is concentrated at the central portion of the alumina to be effective in preventing the central portion from being deteriorated by the heat of the exhaust gas to extend the life of the converter eoteo to.
