Is provided.
여기서 도 2A에 도시된 단면도는 자동차의 배기부에 구비된 촉매컨버터를 도시한 단면도로 배기가스가 유입되는 유입구(1a)와 유출되는 유출구(1b)가 좌/우로 구비되며 이 좌/우 유입구(1a) 사이에 촉매본체(2)가 놓여지도록 공간이 구비되는 하우징(1)과, 이 하우징(1)의 내부에 위치되며 양평면이 개방된 원통의 내부로 격자형의 서포트(2a)가 구비되어져 상기 하우징(1)의 유입구(1a)를 통해 유입되는 배기가스가 서포트(2a)의 내부를 통과하며 유출구(1b)쪽으로 진행되도록 된 촉매본체(2)로 구성되어진다.2A is a cross-sectional view showing a catalytic converter provided in the exhaust part of the vehicle. The inlet 1a through which the exhaust gas flows in and the outlet 1b through which the exhaust gas flows out are provided to the left and right sides. The housing 1 is provided with a space for placing the catalyst body 2 therebetween, and the lattice support 2a is provided inside the cylinder having two open planes inside the housing 1. The exhaust gas flowing through the inlet port 1a of the housing 1 passes through the inside of the support 2a and consists of a catalyst body 2 which is allowed to proceed toward the outlet port 1b.
여기서, 상기 촉매본체(2)의 내부에 구비되는 격자형 서포트(2a)는 상기 유입구(1a)를 통해 유입되는 일산화탄소 및 질소산화물 등과 화학반응을 일으켜 배기가스의 유해성분을 산화 및 환원시키도록 백금 등의 촉매가 코팅 되어진다.Here, the grid support (2a) provided inside the catalyst body (2) is a chemical reaction with carbon monoxide and nitrogen oxides introduced through the inlet (1a) to oxidize and reduce the harmful components of the exhaust gas platinum The catalyst is coated.
따라서, 상기 유입구(1a)를 통해 하우징(1)의 내부로 유입된 인체에 유해한 배기가스가 내부에 구비되는 원통형의 촉매본체(2)를 통과하는 한편, 촉매본체(2)의 내부로 구비된 격자형의 서포트(2a)에 코팅된 촉매와 화학반응을 일으키도록 되어 인체에 해가되는 유해성분이 제거된 배가가스를 유출구(1b)를 통해 배출된다.Accordingly, the exhaust gas harmful to the human body introduced into the housing 1 through the inlet 1a passes through the cylindrical catalyst body 2 provided therein, and is provided inside the catalyst body 2.
