Abstract

본 발명은 2-행정 대형 디젤엔진의 배기가스중의 아산화질소함량의 저감방법에 관한 것으로서, 최소한 하나의 실린더(5)로 이루어지고, 터빈(8)과 압축기(2)로 구성된 과급군이 구비된 엔진에 관한 것이다. 압측행정중에 실린더는 과급군에 의해 새로운 공기로 충진되고, 압축행정이 종료할 무렵에 연료를 분사한다. 연소동작증에 실린더내에서 생성된 배기가스량으로부터 최소 5 내지 최대 40중량%, 바람직하게는 최대20중량%의 양이 실린더(5)내에 잔류된다. 이 잔류된 배기가스가 후속의 압축행정중에 유입되는 새로운 공기와 혼합되고, 이에 따라서 실린더내의 산소농도가 저감된다.
