Abstract

본 발명은 3원 촉매 컨버터에 내부에 공급된 배기가스를 2단계로 정화하도록 설치한 제1,2단계 촉매 담체와, 상기 제1단계 촉매담체와 제2단계 촉매담체의 사이에 외기를 공급하는 3차 공기 공급수단으로 구성한 배기유해가스 저감장치를 제공함으로써, 엔진의 고속 운전시에도 효과적인 유해가스 저감성능을 확보할 수 있다.The present invention provides the first and second stage catalyst carriers installed in the three-way catalytic converter to purify the exhaust gas supplied in two stages, and supplies the outside air between the first stage catalyst carrier and the second stage catalyst carrier. By providing an exhaust gas abatement device composed of tertiary air supply means, it is possible to ensure effective harmful gas reduction performance even at high speed of engine operation.
