Description
본 고안은 배기계의 구조적 특성에 기인한 배기가스의 유동 편중을 분산시켜 정화효율을 증대시킬 수 있는 구조의 촉매컨버터용 지지원통에 관한 것이다.The present invention relates to a support cylinder for a catalytic converter having a structure that can increase the purification efficiency by dispersing the flow bias of the exhaust gas due to the structural characteristics of the exhaust system.
엔진(11)으로부터 배기되는 배기가스는 도 3에 도시하는 것과 같이 배기매니폴드(12)와 촉매변환기(13) 및 배기파이프(14)를 통해 차량 후방으로 배출되어지게 된다.The exhaust gas exhausted from the engine 11 is exhausted to the rear of the vehicle through the exhaust manifold 12, the catalytic converter 13, and the exhaust pipe 14 as shown in FIG.
그러나 도시하는 것과 같이 엔진(11)으로부터 배기된 배기가스는 배기매니폴드(12)와 촉매변환기(13) 및 배기파이프(14)를 거치면서 그 방향이 180℃ 전환되어지게 되므로 배기매니폴드(12)와 촉매변환기(13)의 플랜지 접속부위(A)에는 곡면으로 유동되는 배기가스에 의해 외측벽면을 따라 흐르게 되는 유동 편중 현상이 발생하게 된다.However, as illustrated, the exhaust gas exhausted from the engine 11 passes through the exhaust manifold 12, the catalytic converter 13, and the exhaust pipe 14, and the direction of the exhaust gas is changed to 180 ° C. ) And a flow bias phenomenon that flows along the outer wall surface by the exhaust gas flowing in the curved surface at the flange connection portion A of the catalytic converter 13.
이에따라 촉매컨버터(13) 내부의 촉매(담체)에 전체 단면적을 통해 배기가스가 고르게 통과하지 못하고 일부에 편중되어 통과하면서 정화되어지기 때문에 유동 편중에 따른 정화 효율이 저하되고 촉매지지체(촉매를 캐닝하고 있는 매트체)의 일부에만 과도한 열적 부하가 작용하여 내구력을 저하시키게 되는 문제점이 있게 된다.Accordingly, the exhaust gas does not pass evenly through the entire cross-sectional area of the catalyst (carrier) inside the catalytic converter 13 and is partially concentrated and purified as it passes, thereby reducing the purification efficiency due to the flow bias, and catalyst support (canning catalyst) Excessive thermal load acts on only a part of the mat body), which lowers the durability.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 배기가스의 유동 편중을 분산시켜 촉매컨버터의 정화 효율을 증대시키고 촉매를 보호하는 매트체의 손상을 방지하여 내구력을 향상시킬 수 있는 촉매컨버터용 지지원통을 제공하는 데 있다.Therefore, the present invention has been proposed in view of the above problems, and its purpose is to disperse the flow bias of the exhaust gas, thereby increasing the purification efficiency of the catalytic converter and preventing the damage of the mat body protecting the catalyst, thereby improving durability. It is to provide a support cylinder for a catalytic converter that can be.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1은 본 고안에 의한 촉매컨버터의 구조를 나타내는 도면이며, 도 2는 본 고안의 촉매컨버터용 지지원통의 측면도이다.1 is a view showing the structure of the catalytic converter according to the present invention, Figure 2 is a side view of the support cylinder for the catalytic converter of the present invention.
촉매컨버터(1)는 담체(2, 촉매)와 담체(2)를 보호하기 위해 캐닝(canning)하고 있는 매트체(3)를 포함하여 구성되어 촉매컨버터 케이스(4)내에 내장되며 지지원통(5)에 의해 지지되도록 장착된다.The catalytic converter 1 comprises a carrier 2, a catalyst, and a mat body 3 canning to protect the carrier 2, which is embedded in the catalyst converter case 4, and has a support cylinder 5 It is mounted to be supported by).
상기 지지원통(5)은 측면에서 보아서 원통형(도 2의 (가)) 또는 타원형(도 2의 (나))이며, 그의 일측을 내측으로 볼록하게(즉 구형상을말함)돌출하도록 성형한 반사부(6)를 보유하고 있다.The support cylinder 5 has a cylindrical shape (a) in FIG. 2 or an oval shape (b) in FIG. 2, and is formed so as to protrude one side thereof inwardly (ie spherical shape). It holds a part (6).
상기 반사부(6)는 곡관으로 접속되는 배기매니폴드에 의해 점차 방향이 전환되면서 유동하게 되는 배기가스가 집중적으로 부딪히게 되는 부위로서 반사부(6)에 부딪히는 배기가스는 사방으로 확산되어 퍼지게 되므로써 촉매(2)의 전체 면적에 걸쳐 배기가스가통과하도록 유도한다.The reflector 6 is a portion where the exhaust gas that flows while being gradually changed in direction by the exhaust manifold connected to the curved pipe intensively collides, and the exhaust gas that strikes the reflector 6 diffuses and spreads in all directions. Induce exhaust gas to pass through the entire area of the catalyst (2).
도면중 부호 7은 배기매니폴드에 접속되는 플랜지이며, 부호 8은 단열을 위한 외통이다.In the figure, reference numeral 7 denotes a flange connected to the exhaust manifold, and reference numeral 8 denotes an outer cylinder for thermal insulation.
이상과 같은 본 고안에 의한 촉매컨버터용 지지원통에 의하면 배기매니폴드에 의해 곡면으로 그의 흐름이 유도되는 배기가스가 집중적으로 부딪히게 되는 지지원통의 해당 부위를 내측으로 볼록하게 돌출시켜 구형의 반사부를 형성하므로써 배기가스가 구형의 반사부에 부딪히면서 사방으로 분산되어져 촉매컨버의 정화효율이 증대되어지게 되며 촉매를 보호하기 위한 매트체의 손상을 방지하여 내구력을 향상시키게 된다.According to the support cylinder for a catalytic converter according to the present invention as described above, the spherical reflector is formed by convexly projecting the corresponding portion of the support cylinder in which the exhaust gas inducing its flow to the curved surface by the exhaust manifold is concentrated. As a result, the exhaust gas is scattered in all directions while hitting the spherical reflector, thereby increasing the purification efficiency of the catalytic converter and improving durability by preventing damage to the mat body for protecting the catalyst.
