Abstract

통내 직접 분사식 실린더 헤드에 있어서의 냉각수 통로의 구조의 개량을 도모하여, 실린더 헤드의 주조 품질의 향상을 도모하는 동시에, 내노킹성의 악화, 기관 출력의 저하를 방지한다.
사중자에 의해 형성되는 냉각수 통로부(1d)를 흡기포트(1a) 하부를 피하여 설치하고, 흡기포트(1a) 하부에는, 독립한 오목부 공간(3)을 형성하여, 시중자(4)에 의해 형성되는 냉각수 통로부(1d)와, 독립한 흡기포트(1a)부의 오목부 공간(3)을 드릴등의 절삭 공구로서 절삭 가공하여 설치한 각 연결통로(1e)로써 연결시키고, 다기통의 냉각수 통로를 형성하도록 하여, 충분한 냉각수 통로가 형성할 수 있도록 하여, 냉각수 통로 형성용의 사중자의 파손의 발생을 방지하여, 실린더 헤드의 주조품질을 높이는 동시에, 냉각수 통로의 용적이 삭감되는 일도 없으며, 내노킹성의 향상을 도모하고, 기관 출력의 향상을 도모하도록 하였다.
