Abstract

본 발명은 자동차에서 배출되는 배기가스를 정화시키는 촉매 변환장치에 관한 것으로서, 종래의 산화 촉매장치는 엔진에서 배출되는 배기가스가 촉매의 활성화온도 도달 여부에 불문하고 항시 전방배기로에서 촉매를 그대로 통과하도록 되어 있어 촉매를 국부적으로만 가열하므로 촉매가 활성화 온도에 도달하는 시간이 상당히 오래 걸렸으며, 이로인해 시동 초기시에 특히 다량 배출되는 배기가스의 유해 물질을 보다 신속하고 효과적으로 정화할 수가 없어 대기 오염을 가중시키는 문제점이 있었다.The present invention relates to a catalytic converter for purifying exhaust gas emitted from an automobile. In the conventional oxidation catalyst apparatus, the exhaust gas discharged from an engine always passes the catalyst as it is in the front exhaust gas regardless of whether or not the activation temperature of the catalyst is reached. Since the catalyst is only locally heated, it takes a very long time for the catalyst to reach the activation temperature, which makes it impossible to purify the harmful substances in the exhaust gases, particularly large quantities, at the initial stage of the start-up. There was a problem that aggravated.

이에따라 본 발명은 배기관(10)의 배기로내에 촉매를 설치함에 있어서 촉매(20) 앞쪽에 위치하는 전방배기로(10a) 양측에는 입구(31)와 출구(32)가 전방배기로(10a)와 연접 설치된 보조배기로(30)를 촉매(20)의 양측면과 접면되게 설치하되 상기 입구(31)와 출구(32)가 엑츄에이터(40)로 조절되는 밸브판(41)에 의해 개폐되게 설치하고, 상기 촉매(20)에는 온도 센서(50)를 설치한 후 온도센서(50)의 감지에 따라 상기 엑츄에이터(40)가 구동되게 하여 촉매가 활성화 온도로의 도달여부에 따라 배기가스의 유로를 변환시켜서 배기가스의 정화를 보다 신속하면서도 효과적으로 이루어지게 한 것이다.Accordingly, in the present invention, in the installation of the catalyst in the exhaust path of the exhaust pipe 10, the inlet 31 and the outlet 32 are located at both sides of the front exhaust path 10a located in front of the catalyst 20. The auxiliary exhaust line 30 is installed in contact with both sides of the catalyst 20 in contact with each other, but the inlet 31 and the outlet 32 are installed to be opened and closed by the valve plate 41 is controlled by the actuator 40, After the temperature sensor 50 is installed in the catalyst 20, the actuator 40 is driven according to the detection of the temperature sensor 50, and the flow path of the exhaust gas is converted according to whether the catalyst reaches the activation temperature. Purification of the exhaust gas was made more quickly and effectively.
