Abstract

[목적] 엔진의 연소실에 공기, 연료를 공급하는 흡기관에 있어서, 엔진의 링 상태에서의 연소를 안정화한다.
[구성] 조리개 밸브(1)을 통과한 공기는 독립 흡기관(40로 나뉘어 갈라져 흡기 밸브(5)를 통과하고 실린더 6에 흡입된다.
여기서, 실린더안에 선희류를 만들기 위해서 보조막(7)과 이것을 바이패스하는 흡기 통로(8)을 설치했다.
통상은 보조 밸브(7)은 열려있지만, 링 연소를 하는 경우나 아이들때나 저온시처럼 연소를 개선하고 싶은 경우는 보조 밸브(7)을 닫고, 흡기를 흡기 통로(8)의 방향에서 실린더(6)안에 공급한다.
이처럼하면, 지향성 있는 공기류를 흡기 밸브(5)가 있는 위치에 공급하는 것으로 독립 흡기관(4)안에 편류할수 있고, 실린더 안에 선회류(9)가 형성된다.
[효과] 본 발명에 의하면, 연료 분무의 편향을 방지할 수 있고, 연소 실안의 혼합기 분포가 균일 또는 점화플러그 주변이 풍부해지기 때문에, 링 연소를 안정화할수 있다.
