자동차용 배기매니폴드의 촉매설치구조Catalyst Installation Structure for Automobile Exhaust Manifold

본 발명은 자동차 엔진의 각 실린더에서 연소된 연소가스를 한 곳으로 모아서 외부로 배출하는 배기매니폴드를 통과하는 배기가스에 포함된 유해성분을 정화할 수 있도록 하는 촉매를 설치하기 위한 자동차의 배기매니폴드 촉매설치구조에 관한 것으로, 더 자세하게는 각 실린더의 배기포트와 대응되는 배기매니폴드의 유입구마다에 촉매를 설치함으로써 정화효율을 향상시킬 수 있도록 개선한 것에 관한 것이다.The present invention is a vehicle exhaust manifold for installing a catalyst to clean the harmful components contained in the exhaust gas passing through the exhaust manifold to collect the combustion gas burned in each cylinder of the automobile engine to one place The present invention relates to a fold catalyst installation structure, and more particularly, to improve the purification efficiency by providing a catalyst at each inlet of the exhaust manifold corresponding to the exhaust port of each cylinder.

일반적으로 자동차의 엔진은 다수의 실린더와 각 실린더의 내부를 왕복운동하는 피스톤을 구비하게 되며, 각 실린더 내부의 연소실에 흡기되어 피스톤에 의해 압축, 팽창(폭발)된 혼합기는 연소 후에 실린더 외부로 배출된다.In general, the engine of a vehicle includes a plurality of cylinders and pistons reciprocating inside each cylinder, and a mixer intaken in the combustion chamber inside each cylinder and compressed and expanded by the piston is discharged to the outside of the cylinder after combustion. do.

상기에서 각 실린더에서 배출되는 연소가스는 배기매니폴드로 유입되고, 배기매니폴드는 각 실린더로부터 유입된 배기가스를 한 곳으로 모아 배기관으로 보내게 된다.In the above, the combustion gas discharged from each cylinder flows into the exhaust manifold, and the exhaust manifold collects the exhaust gas introduced from each cylinder into one place and sends it to the exhaust pipe.

상기 배기매니폴드는 도 1과 같이 일측에 엔진의 각 실린더의 배기포트와 접속되는 다수의 유입구(11')가 마련되고, 타측에 배기관(20')과 접속되는 하나의 유출구(12')가 마련된 형태를 갖는다.The exhaust manifold is provided with a plurality of inlets 11 'connected to the exhaust port of each cylinder of the engine on one side as shown in FIG. 1, and one outlet 12' connected to the exhaust pipe 20 'on the other side. It has a prepared form.

한편 본 발명이 관계하는 촉매는 상기 배기매니폴드(10')로부터 배출되는 배기가스에 포함된 유해성분을 정화하여 대기의 오염을 저감할 수 있도록 하는 것인 바, 종래에 있어서 이 촉매의 설치구조는 도 1과 같이 캔닝(Canning)성형한 케이스(33')의 내부에 인터램매트(32')로 감싼 촉매모노리스(31')를 설치한 단 하나의 촉매조립체(30')를 배기매니폴드(10')의 유출구(12')의 하단에 설치한 형태의 것이 주로 사용되었다.On the other hand, the catalyst according to the present invention is to clean the harmful components contained in the exhaust gas discharged from the exhaust manifold (10 ') to reduce the pollution of the air, the installation structure of the catalyst in the prior art 1 shows the exhaust manifold of only one catalyst assembly 30 'having a catalyst monolith 31' wrapped with an interrammat 32 'inside a canning molded case 33'. The thing of the form provided in the lower end of the outlet 12 'of 10' was mainly used.

이 종래구조는 배기매니폴드(10')의 유출구(12')를 통해 배출되는 배기가스가 촉매모노리스(31')를 거치는 동안 유해성분이 정화되도록 한 것이지만 각 실린더의 배기포트와 접속된 각 유입구(11')로 유입되어 유출구(12')쪽으로 이동하는 배기가스의 흐름이 촉매모노리스(31')의 일정부위에만 집중되므로 정화효율이 크게 저하될 뿐 아니라 캔닝성형으로 제작한 케이스(33')에 촉매모노리스(31')를 설치하여야 하는 등 촉매조립체(30')의 제작이 번거롭고, 그 제작단가가 높은 문제가 있었다.This conventional structure allows harmful components to be purified while the exhaust gas discharged through the outlet 12 'of the exhaust manifold 10' passes through the catalyst monolith 31 ', but each inlet port connected to the exhaust port of each cylinder ( 11 '), the flow of exhaust gas flowing into the outlet 12' is concentrated only at a certain portion of the catalyst monolith 31 ', so that the purification efficiency is greatly lowered and the case 33' is manufactured by canning molding. The production of the catalyst assembly 30 'is cumbersome, such as the need to install the catalyst monolith 31', and there is a problem of high production cost.

본 발명은 상기 종래의 실정을 감안하여 안출한 것이며, 그 목적은 촉매의 일정부위에만 배기가스가 집중적으로 접촉되는 것을 방지하여 배기가스의 정화효율을 향상시킬 수 있도록 함은 물론 촉매모노리스의 제작과 설치를 간편하게 할 수 있도록 하는 것에 의해 제작원가와 설치원가를 절감할 수 있도록 하는 자동차의 배기매니폴드 촉매설치구조를 제공하는 데에 있는 것이다.The present invention has been made in view of the above-mentioned conventional situation, and its object is to prevent the exhaust gas from coming into intensive contact only at a certain portion of the catalyst to improve the purification efficiency of the exhaust gas, as well as to manufacture the catalyst monolith. It is to provide a vehicle exhaust manifold catalyst installation structure that can reduce the manufacturing cost and installation cost by simplifying the installation.
