Claims (2)

  1. 엔진의 소정크랭크각위치마다 신호를 발생하는 크랭크각센서와, 특정기통을 검출하는 기통식별수단과, 각 기통마다 부착된 연료분사밸브 및 엔진의 실화상태를 검지하는 실화검지수단을 갖추고, 실화검지시에는 실화기통에 대응한 연료분사밸브를 폐지함과 아울러, 소정기간 연료분사밸브를 폐지한 경우는 연료분사밸브의 폐지를 해제하고 재차 실화검지수단에 의해 실화상태를 검지할 수 있도록 한 것을 특징으로 하는 연료제어장치.
  2. 제1항에 있어서, 실화검지때에는 연료분사밸브를 폐지함과 아울러 이상경고를 행하고, 연료분사밸브의 폐지를 해제할 경우에는 이 이상경고를 해제치 않는 것을 특징으로 하는 연료제어장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
