Abstract
본 발명은 자동차의 배기 가스 통로상에 설치되어 배기 가스를 정화시키는 촉매로에 관한 것으로, 촉매의 중심부와 외곽부를 각각 개별적으로 형성하여 서로 삽입시키게 되며, 이 때 촉매의 중심부는 외곽부에 비하여 높은 면적 밀도를 갖도록 형성되어 있는 것을 특징으로 하는 자동차의 촉매장치를 제공한다.The present invention relates to a catalyst furnace for purifying exhaust gas installed on an exhaust gas passage of an automobile, wherein the center and the outer portion of the catalyst are separately formed and inserted into each other, wherein the center of the catalyst is higher than the outer portion. Provided is an automobile catalyst apparatus, which is formed to have an area density.
Description
본 발명은 자동차의 촉매장치에 관한 것이다.The present invention relates to a catalytic device of an automobile.
일반적으로, 자동차의 배기 가스에서 일산화탄소와 탄화 수소 등으로 이루어진 다량의 유해 성분을 포함하고 있으며, 이러한 유해 물질을 정화시키기 위하여 촉매가 사용되고 있으며, 이러한 촉매는 몸체로서의 담체와 담체의 배기 가스 통로 상에 도포되어 있는 촉매층으로 이루어진다.In general, a large amount of harmful components consisting of carbon monoxide, hydrocarbons, and the like are contained in the exhaust gas of automobiles, and catalysts are used to purify these harmful substances, and these catalysts are used on the carrier as a body and the exhaust gas passage of the carrier. It consists of a catalyst layer applied.
그런데, 종래에 있어서, 이러한 촉매는 세라믹 담체나 금속 담체에 상관 없이 모두 동일한 셀 밀도를 적용하고 있으나 실제로 배기 가스의 유속이 촉매의 중앙부로만 집중되는 현상이 있기 때문에, 촉매 중앙부에 촉매 효율이 갈수록 저하되는 문제점이 있었다.By the way, in the related art, all of these catalysts use the same cell density regardless of the ceramic carrier or the metal carrier. However, since the flow rate of the exhaust gas is concentrated only at the center of the catalyst, the catalyst efficiency gradually decreases at the center of the catalyst. There was a problem.
따라서, 본 발명은 이러한 종래의 문제점을 해결하기 위하여 안출된 것으로서, 이러한 촉매의 구조를 개선하여 촉매 전체의 효율을 일정하게 유지시키는 것을 목적으로 한다.Accordingly, the present invention has been made to solve such a conventional problem, and an object of the present invention is to improve the structure of such a catalyst to maintain a constant efficiency of the catalyst as a whole.
도 1은 본 발명에 따른 자동차의 촉매장치의 구조를 개략적으로 나타내는 단면도.1 is a cross-sectional view schematically showing the structure of a catalytic device of a vehicle according to the present invention.
*도면의 주요부분에 대한 부호의 설명** Description of the symbols for the main parts of the drawings *
1 : 중심부2 : 외곽부1: center 2: outer part
상기 목적을 달성하기 위하여, 본 발명은, 자동차의 배기 가스 통로상에 설치되어 배기 가스를 정화시키는 촉매로서, 촉매의 중심부와 외곽부를 각각 개별적으로 형성하여 서로 삽입시키게 되며, 이 때 촉매의 중심부는 외곽부에 비하여 높은 면적 밀도를 갖도록 형성되어 있는 것을 특징으로 하는 자동차의 촉매장치를 제공한다.In order to achieve the above object, the present invention, the catalyst is installed on the exhaust gas passage of the vehicle to purify the exhaust gas, the center and the outer portion of the catalyst is formed separately and inserted into each other, wherein the center of the catalyst Provided is a catalyst device for an automobile, which is formed to have a high area density compared to the outer portion.
[실시예]EXAMPLE
이하, 첨부된 도면을 참조하여 본 발명의 양호한 실시예를 보다 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
도 1은 본 발명에 따른 자동차의 촉매장치의 구조를 나타내는 단면도이다.1 is a cross-sectional view showing the structure of a catalyst device of a vehicle according to the present invention.
도시된 바와 같이, 본 발명에 따르면, 촉매의 중심부(1)와 외곽부(2)를 각각 개별적으로 형성하여 서로 삽입시키게 되며, 이 때 촉매의 중심부(1)는 외곽부(2)에 비하여 높은 면적 밀도를 갖도록 형성되어 있다.As shown, according to the present invention, the central portion 1 and the outer portion 2 of the catalyst are separately formed and inserted into each other, wherein the central portion 1 of the catalyst is higher than the outer portion 2. It is formed to have an area density.
이상 상술된 바와 같이, 본 발명에 따른 자동차의 촉매장치에 의하면, 촉매의 중심부의 셀 밀도를 외곽부에 비하여 향상시키므로써 촉매의 내구성이 향상되는 효과가 있다.As described above, according to the catalyst device of the automobile according to the present invention, the durability of the catalyst is improved by improving the cell density of the central portion of the catalyst compared to the outer portion.
