Abstract

배기 개스의 재순환 및 재순환된 배기 개스의 계층화를 채용하며, 공기를 실린더내로 흡입시키는 흡기 밸브(3)와 공조하는 최소한 하나의 흡기구(11)와 통하며 배기 개스를 실린더로부터 배출시키는 배기 밸브(5,6)와 공조하는 최소한 하나의 배기고(7,8)와 통하고 피스톤을 수용하는 최소한 하나의 실린더(2)를 지니는 형태의 스파크 점화 엔진은, 재순환된 배기 개스가 엔진 작동 시간에 일부분동안 흡입구(11)를 통해 단독으로 실린더(2)내로 흡입됨으로써, 재순환된 배기 개스 및 공기가 상이한 시간임에도 불구하고 같은 흡입구를 통해 도입된다.
