제1도는 본 원발명의 센서부분의 일실시예를 나타낸 설명도.
제4도A는 고체전해질에 공급하는 전류와 고체전해질의 양면에 설치된 전극에 유기되는 전압과의 관계를 나타낸 파형도.
제4B도는 공기과잉율과 검출동작시간(센싱동작시간)과의 관계를 나타낸, 즉 출력특성을 나타낸 특성도.
제7도는 본원 발명의 일실시예를 나타낸 전체구성도.

Claims (1)

  1. 내연기관의 배기가스중에 포함되는 산소의 확산을 조정하는 확산저항체(2)를 한쪽에 설치하며, 그 다른쪽이 대기에 접하고 있는 고체전해질(1)로 이루어진 공연비검출장치에 있어서, 일정전류(Ib)를 소정시간 상기 고체전해질(1)에 가하고, 이것에 의해 대기중의 산소를 확산저항체(2)에 보내는 수단(5,12,7a,7b)과, 역극성(逆極性)의 일정전류(Is)를 상기 고체전해질에 가함으로써 확산저항체(2)내의 산소를 뽑아내는 수단(5,12,8a,8b)과, 이 뽑아낼 때에 고체전해질의 양면간의 전압치가 소정치에 도달하기까지의 뽑아내는 시간(ts)에 의거하여 공연비를 검출하는 수단(13)으로 이루어진 것을 특징으로하는 공연비 검출기.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
