Abstract
Description
Claims (1)
- 피스톤과 실린더 블럭 상면에 고정된 실린더 헤드 사이에 연소실(5)을 형성하고, 상기 실린더 헤드의 연소실을 형성하는 하면에 설치된 흡기 밸브 시트를 거쳐 연소실내에 흡기가 유입되는 내연기관에 있어서, 상기 실린더 헤드에는 실린더 헤드 측면으로부터 상기 밸브 시트의 중심을 향해 연장하는 흡기 포오트(9)가 설치되고, 상기 흡기 포오트는 흡기 유선에 따라 동시에 실린더 헤드의 상하 방향 단면에 있어서 상반부를 이루는 스트레이트부(13)와, 하반부를 이루는 소용돌이부(15)로 구성되며, 상기 소용돌이부는 직선부(15b)와 소용돌이실(15a)로부터 형성되며, 상기 소용돌이실은 상기 흡기 밸브 시트 근방 위치의 상기 직선부의 외주에 돌출하고, 또한 상기 직선부는 실린더 헤드 하면측에 상기 흡기 밸브 시트를 거쳐 상기 연소실에 연통하여 형성되고, 더우기 상기 스트레이트부만을 실질적으로 개폐하는 밸브(17)를 설치하여, 내연기관의 저부하시에 상기 밸브를 완전 폐쇄 상태로 상기 소용돌이부로 흡기를 유도하도록 제어하는 개폐기구인 진공모터(27)를 구비하는 것을 특징으로 하는 흡기 포오트 장치.
