Claims (2)

  1. 연료 제어변의 작동에 따라 내연기관에 연료를 공급시키는 수단, 상기 내연기관의 흡기통로내에 설치되고 흡입공기량을 검출하는 흡기량센서, 이흡기량센서의 출력을 바탕으로하여 내연기관의 요구연료량을 연산하며 그기본치에 의하여의 상기 연료제어변을 제어하여 내연기관에 연료를 공급하도록 상기수단을 제어함과 동시에 내연기관의 배기관에 부착되고 공연비에 따라 출력을 발생시키는 공연비센서의 출력을 받아 공연비가 소망치로되도록 상기기본치를 부귀환보정하는 연료제어수단을 갖추고있으며, 이 연료제어수단은 상기 흡기량센서의 출력이 소정대표점의 근방에 있을때 상기 부귀 환보정량 또는 이에 관계되는량을 메모리에 리드인(read in)시키는 수단과, 상기 메모리의 내용에 의하여 상기 기본치를 보정하는 수단과, 캐니스터에 포착된 증발연료를 내연기관의 흡기계에 퍼지하는 통로에 설치된 퍼지제어변을 내연기관의 운전상태에 따라 개폐제어하는 수단과, 상기 퍼지제어변의 상태를 바탕으로 하여 상기 메모리의 리드인작동 금지기간을 결정하며 이간중에는 상기 메모리의 리드인동작을 금지시키는 수단등을 갖고 있는 연료제어장치.
  2. 청구범위 제1항에 있어서, 메모리의 리드인동작을 금지시키는 수단은 퍼지제어변의 개변된후 부터 타이머어 의하여 설정된 일정기간, 또는 퍼지통로의 유량적산치가 설정치에 도달할때까지의 기간에 해당하는 기간중에는 메모리의 리드인동작을 금지시키는 연료제어장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
