Abstract

본 발명은 직접분사식 가솔린엔진에 관한 것으로서, 인젝터(13)가 연소실(3A)에 설치되어 연료를 직접 분사시킬 수 있도록 한 직분식엔진(1)에 있어서, 상기 직분식엔진(1)의 실린더블록(2) 상부에 구비한 실린더헤드(10)에 흡기포트인 역텀블포트(11)를 연소실(3A)과 연통 형성하고, 역텀블포트(3A)의 상부에는 서지탱크(18)를 직접 연결 설치하여 직분식엔진(1)의 높이 크기를 최소화시킨 것으로 실차 적용에 있어 직분식 엔진의 적용이 보다 용이하고, 혼합가스를 점화플러그로 와류상태에서 유동시키는 피스톤의 캐비터 형상 가공을 보다 용이하게 할 수 있는 효과가 있다.
