Abstract: 본 발명은 자동차 엔진의 다단 피스톤 시스템에 관한 것으로서, 커넥팅 로드에 피스톤 핀으로 연결된 메인 피스톤과, 상기 메인 피스톤 둘레에 다중 구조로 겹쳐진 복수의 다중 피스톤들로 이루어지고; 상기 다중 피스톤들에는 상기 피스톤 핀이 삽입되는 슬롯이 각각 형성되어 상기 메인 피스톤이 상측으로 이동될 때 동일 높이까지 함께 이동되도록 구성됨으로써, 본 발명은 고출력화가 가능해지는 동시에 소음 발생도 줄일 수 있으며, 별도의 피스톤 링이 사용되지 않기 때문 엔진 오일의 소모량을 줄일 수 있는 효과가 있다.

Abstract: 본 발명은 자동차 엔진용 실린더 헤드 구조에 관한 것으로서, 플러그 장착홀의 형상을 변경하여 배기포트와 플러그 장착홀 사이의 두께를 증대시키고, 두께가 증대된 배기포트와 플러그 장착홀 사이의 공간에 워터 자켓을 보다 깊게 형성하여 구성함으로써, 워터 자켓의 냉각 효과가 상승됨에 따라 엔진 운전 중 실린더 헤드 금속면의 온도, 특히 배기포트 및 플러그 장착홀 주위 금속면의 온도가 크게 낮아질 수 있고, 이에 내구 신뢰성이 더욱 향상되어지는 자동차 엔진용 실린더 헤드 구조에 관한 것이다. 이러한 본 발명의 실린더 헤드 구조는, 배기포트와 플러그 장착홀 사이의 두께가 증대될 수 있도록, 플러그 장착홀 상단에 마련된 플러그 좌면부의 상하 구간 길이를 짧게 형성하고, 이와 함께 플러그 장착홀의 태핑 가공부를 상측으로 길게 연장 형성하는 한편, 두께가 증대된 배기포트와 플러그 장착홀 사이의 공간에서 워터 자켓의 깊이가 증대될 수 있도록 워터 자켓 하단부가 태핑 가공부 상단 높이 아래까지 깊게 연장 형성되어 있는 것을 특징으로 한다.
