Abstract
본 고안은 엔진에서 연소된 배기 가스를 정화시키는 촉매의 구조에 관한 것으로, 촉매와 매트가 취부되는 바디는 처판으로 구성되어 있으며, 이러한 바디에 촉매가 고정된 후 상부에 프론트 프랜지가 결합되는 것을 특징으로 하는 자동차의 촉매 구조를 제공한다.The present invention relates to a structure of a catalyst for purifying exhaust gas burned in an engine. The body on which the catalyst and the mat are mounted is composed of a counter plate, and the front flange is coupled to the upper part after the catalyst is fixed to the body. A catalyst structure of an automobile is provided.
Description
본 고안은 자동차의 배기 파이프 상에 장착되어 배기 가스를 정화시키기 위한 촉매에 관한 것이다.The present invention relates to a catalyst mounted on an exhaust pipe of an automobile to purify exhaust gas.
일반적으로 날로 강화되어가는 배기 가스-규제를 만족하기 위하여 배기 매니폴드상에는 촉매가 부착되고 있으며, 이러한 촉매를 MCC(maifild closed catalyst)라 한다. 이러한 촉매는 시동직후 냉간 구간에서 나오는 높은 배기 가스의 온도를 이용하여 빠른 시간내에 배기 정화가 가능하다.Generally, catalysts are attached on the exhaust manifold to satisfy the exhaust gas-regulation, which is increasingly strengthened. Such a catalyst can purify exhaust gas in a short time by using the temperature of the high exhaust gas from the cold section immediately after starting.
그런데, 이러한 종래의 촉매 구조에 있어서, 이러한 촉매는 엔진 롬내의 레이 아웃 관계상 크게 만들지 못하기 때문에 주로 주철을 이용하여 주물 형태로 만든 뒤 가공하는 것이 일반적이나 무게, 가공성, 조립성 등에서 매우 불리한 문제점이 있었다.However, in such a conventional catalyst structure, since such a catalyst cannot be made large in relation to the layout in the engine ROM, it is common to make the casting after casting it mainly using cast iron, but it is very disadvantageous in terms of weight, processability, and assembly properties. There was this.
따라서, 본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출된 것으로서, 이러한 촉매의 구조를 개선하여 가공성 및 조립성이 향상된 촉매를 제공하는 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 provide a catalyst having improved processability and granularity by improving the structure of such a catalyst.
도 1은 본 고안에 따른 자동차의 촉매 구조를 나타내는 분해 사시도.1 is an exploded perspective view showing a catalyst structure of a vehicle according to the present invention.

3:매트4:프론트 플랜지3: Matt 4: Front flange
상기 목적을 달성하기 위하여, 본 고안은, 엔진에서 연소된 배기 가스를 정화시키는 촉매의 구조로서, 촉매와 매트가 취부되는 바디는 처판으로 구성되어 있으며, 이러한 바디에 촉매가 고정된 후 상부에 프론트 플랜지가 결합되는 것을 특징으로 하는 자동차 촉매 구조를 제공한다.In order to achieve the above object, the present invention, as a structure of a catalyst for purifying exhaust gas burned in an engine, the body on which the catalyst and the mat is mounted is composed of a mounting plate, the front of the front of the catalyst fixed to the body An automobile catalyst structure is characterized in that the flange is coupled.
[실시예]EXAMPLE
이하, 첨부된 도면을 참조하여 본 고안의 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 고안에 따른 자동차의 촉매 구조를 나타내는 분해 사시도이다.1 is an exploded perspective view showing a catalyst structure of a vehicle according to the present invention.
도시된 바와 같이, 본 고안에 따르면, 촉매(2)와 매트(3)가 취부되는 바디(1)는 처판으로 구성되어 있으며, 이러한 바디(1)에 촉매(2)가 고정된 후 상부에 프론트 플랜지(4)가 결합된다.As shown, according to the present invention, the body 1, on which the catalyst 2 and the mat 3 are mounted, consists of a plate, and the front of the upper body after the catalyst 2 is fixed to the body 1. The flange 4 is engaged.
이상 상술된 바와 같이, 본 고안에 따른 촉매의 구조에 의하면, 담체와 매트를 둘러싼 바디를 철판으로 구성하여 용접시킨 후 플랜지부를 부착시키므로써 촉매의 크기가 감소되고 조립성 및 가공성이 향상되는 효과가 있다.As described above, according to the structure of the catalyst according to the present invention, by attaching the flange portion after welding the body and the body surrounding the carrier and the mat to reduce the size of the catalyst and improve the assembly and processability There is.
