Abstract

3 흡입 밸브 엔진에 있어서 연비의 향상을 위한 것이다.
흡입 포트(11, 12, 13)를 분사 노즐(17)로부터 연소실(10)사이에 서로 독립되고, 흡기가 포느 상벽(12a)에 연하여 흐르고, 연소실(10)에 있어서 종와류 층상 흐름이 되는 단면 역삼각형으로 형성되고, 3개의 흡입 포트의 중앙부에 위치하고 있고 점화플러그(16)에 대향하고 있는 포트를 혼합기 흡입 포트(12)로 하고, 이 포트(12)의 양측에 배치된 포트를 공기 흡입 포트(11, 13)라하고, 포트(12)에 대해서만 연료를 공급하는 연료 공급 수단(17)을 설치하고, 연소실(10)내에 흡입된 혼합기가 포트(12)로부터 흡입된 종와류(12A)와 포트(11, 13)로부터 흡입된 공기의 종와류(11A, 13A)가 종와류(12A)를 끼워 3층상의 종와류를 형성하여 흐르고 있는 것을 특징으로 한다.
