Claims (2)

  1. 4싸이클 내연기관에 있어서, 흡기 밸브를 상사점 후에 개방하여 하사점을 지난후에 폐쇄하고, 배기밸브는 상사점을 지난 후 폐쇄하며, 배기 밸브가 폐쇄된 후 흡기 밸브를 개방하는 것을 특징으로 하는 4싸이클 내연기관.
  2. 4싸이클 내연기관에 있어서, 캠이 동일 반경을 가지되 캠축 중심과 캠의 중심을 잇는 중심선에 대하여 대칭이 되도록 돌출부가 형성되고 그 돌출 부분을 여러 부분으로 나누어 변위(y)를 a+bx+cx2+dx3+ex4+fx5의 방정식으로 계산하되 상기 각 계수들은 다음과 같이,
    매트릭스로 계산하여 상기 나누어진 각 부분들의 곡률 반경을 결정하는 것을 특징으로 하는 4싸이클 내연기관.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
