Claims (5)
- 배기가스 중의 잔존 산소량 또는 가연성 성분에서 기관의 공연비를 검출하기 위해 공연비에 비례한 출력을 내는 공연비 센서를 사용하며, 이 공연비 센서로부터의 신호를 근거로, 기관에 공급하는 혼합기의 공연비를 폐 루프(閉, loop)제어하는 공연비 제어장치에 있어서, 제어하고자 하는 설정공연비에 따라 공연비 제어정수를 변화시키는 것을 특징으로 하는 공연비 제어장치.
- 제1항에 있어서, 공연비 제어정수로서 적분정수와 비례정수를 가지며, 이 2개의 정수 중 어느 한쪽 또는 양쪽을 이 설정 공연비에 따라 변화시키는 것을 특징으로 하는 공연비 제어장치.
- 제2항에 있어서, 비례적분정수를 공연비가 이론 공연비보다 큰 경우와 작은 경우로 변화시키는 것을 특징으로 하는 공연비 제어장치.
- 제3항에 있어서, 비례, 적분정수를 이 설정 공연비에 따라 연속적으로 변화시키는 것을 특징으로 하는 공연비 제어장치.
- 제3항에 있어서, 공연비가 이론 공연비보다 큰 경우의 비례, 적분정수에 대해 공연비가 이론공연비보다 작은 경우의 비례, 적분정수쪽이 작은 것을 특징으로 하는 공연비 제어장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
