Description

촉매 보호법
[도면의 간단한 설명]
재1도는 과열로부터 촉매를 보호하는 방법을 설명하는 흐름도이다.
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (3)

  1. 촉매를 과열로부터 보호하기 위한 방법에서, 영향을 받은 실린더로의 연료 공급을 차단하기 위하여 실린더에서 불점화가 발생하는지를 판단하도록 실린더 선택 불점화 인식 방법이 사용되는 촉매를 과열로부터 보호하기 위한 방법에 있어서, 영향을 받은 실린더로의 연료 공급이 차단될 때 나머지 실린더는 희박 혼합으로 공급되는 것을 특징으로 하는 과열로 부터의 촉매 보호 방법.
  2. 제1항에 있어서, 영향을 받은 실린더로의 연료 공급이 이 실린더의 주입 밸브에서의 고장으로 인하여 대응 차단 신호에도 불구하고 차단되면, 모든 실린더에 대한 혼합이 농후해지고 엔진 전력은 제한되는 것을 특징으로 하는 과열로부터의 촉매 보호 방법.
  3. 제1항에 있어서, 엔진 전력이 제한되는 것을 특징으로 하는 과열로부터의 촉매 보호 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
