Abstract: 병렬 2기통 엔진의 한쌍의 실린더 보어의 간격을 가급적 좁혀 엔진의 크랭크 샤프트 축선 방향의 치수를 소형화한다. 병렬 2기통 엔진(E)은 분할면(P 1 )에서 분할된 크랭크 케이스 좌반체(3 L ) 및 크랭크 케이스 우반체(3 R )로 이루어진 크랭크 케이스(2)와, 한쌍의 실린더 보어(15 L , 15 R )를 가지는 실린더 블록(4)을 갖추고 있다. 상기 분할면(P 1 )은 한쌍의 실린더 보어(15 L , 15 R )의 중간면(C)에 대해 우방향으로 거리(D)만큼 치우쳐 있고, 실린더 블록(4)을 크랭크 케이스(2)에 결합하도록 상기 중간면(C) 상에 배치된 볼트(49 3 )는 상기 분할면(P 1 )과 간섭없이 크랭크 케이스 좌반체(3 L )에 나사식으로 삽입된다. 이것에 의해, 한쌍의 실린더 보어(15 L , 15 R )를 접근시켜 엔진(E)의 축선(L) 방향의 치수를 소형화할 수 있다.
