Claims (8)

  1. 내연기관의 흡기통로내에 설치된 열선식 흡기량 센서의 출력에 기준하여 내연기관의 요구연료량을 연산하고 그 연산치에 기준하여 연료 제어밸브를 제어하여 내연기관에 소정의 연료를 공급하는 장치에 있어서,
    내연기관 정지후에 열선을 통상동작온도를 상회하는 온도까지 가열하여 열선의 표면부착물을 소각시키는 고온소각(burn off) 제어수단과, 상기 열선식 흡기량센서의 이상을 검출하고 상기 고온소각 제어부의 동작을 정지시키는 이상 검출부를 구비한 것을 특징으로 하는 연료제어장치.
  2. 제1항에 있어서,
    상기 이상 검출부에는 이상 검출에 기준하여 고장신호를 출력하는 신호출력부가 있는 것을 특징으로 하는 연료제어장치.
  3. 제1항 또는 제2항에 있어서,
    상기 이상상태의 검출을 시스템의 전압저하를 검출하는 방식으로 행하도록 한 것을 특징으로 하는 연료제어장치.
  4. 제1항 또는 제2항에 있어서,
    이상 상태의 검출을 열선식 흡기량센서의 출력레벨의 이상을 검출하는 방식으로 행하도록 한 것을 특징으로 하는 연료제어장치.
  5. 제4항에 있어서,
    고온소각 제어부의 동작을 정지하였을 때는 연료제어밸브의 동작을 정지하든가 또는 흡기량 센서의 출력과는 관계없이 구동하도록한 연료제어장치.
  6. 제4항 또는 제5항에 있어서,
    흡기량센서의 출력레벨이 통상의 동작레벨을 벗어나서 저하 또는 상승한 것에 의하여 이상을 판정하는 연료제어장치.
  7. 제4항 또는 제5항에 있어서,
    고온소각 제어를 실행하고 있는 동안의 흡기량 센서출력 레벨이 소정범위에 없는 것에 의하여 이상을 판정하는 연료제어장치.
  8. 제2항에 있어서,
    상기 이상검출부가 고온소각 제어부의 작동정지의 이력을 기억하고 복수회의 작동정지로 고장표시를 행하도록 한 것을 특징으로하는 연료제어장치.
