Abstract
본 발명은, 배기가스중에 포함되는 SO 3 의 비율이 높은 경우나 배기가스의 온도가 저하된 영역에서 요소수가 분무되는 경우에도 부생성물의 생성을 억제한다.
(해결수단)
엔진(1)의 배기포트(1a)에 접속된 배기연락관(2)으로부터 배출된 배기가스를 집합시키는 배기 매니폴드(3)와, 터보차져(4)의 터빈(4a) 상류측의 배기통로(5)와의 사이에 설치된 탈초반응기(6)를 구비한 배기가스 정화장치(7)에 있어서 상기 탈초반응기(6)의 SCR촉매(6a)에 대하여 암모니아를 공급 가능한 요소수 분무구조이다. 배기 매니폴드(3)내에, 터보차져(4)의 컴프레서(4b) 하류측의 급기통로(8)로부터 분기된 분기관(9)과 접속된 증발관(10)을 배치함과 아울러, 증발관(10)내를 통과하는 공기에 대하여 요소수를 분무하는 노즐(11)을 설치한다.
(효과)
배기통로의 부식이나 폐색을 방지하고, SCR촉매의 성능도 양호하게 유지할 수 있다.
