Abstract

본원 고안은 엔진의 배기가스 정화장치에 관한 것으로서, 엔진의 1차촉매와 2차촉매가 분리 배치되고 흡기매니폴드의 서지탱크로부터 상기 1차촉매와 2차촉매의 사이로 공기 파이프가 설치되어 있으며 상기 2차촉매의 후방으로 배기관의 일단에는 2차 산소감지센서가 설치되어 ECU와 전기적으로 연결되고 상기 ECU에 의해 제어되는 솔레노이드 밸브에 의해 상기 공기 공급파이프를 개폐토록 함으로서 배기가스의 정화성능을 향상시켜서 대기오염을 줄일수 있도록 하는 효과를 가지는 것이다.The present invention relates to an exhaust gas purifying apparatus of an engine, wherein the primary catalyst and the secondary catalyst of the engine are disposed separately and an air pipe is installed between the primary catalyst and the secondary catalyst from the surge tank of the intake manifold. A secondary oxygen sensor is installed at one end of the exhaust pipe to the rear of the secondary catalyst to electrically open and close the air supply pipe by a solenoid valve controlled by the ECU to improve the purification performance of the exhaust gas. It has the effect of reducing air pollution.
