Claims (1)

  1. 내연기관의 흡입공기량을 카르만와 유량 검출장치에 의하여 검출하고 이검출출력을 상기 내연기관의 소정크랭크각의 구간에서 검출하는 AN검축수단과, 이 AN검출수단에서 얻은 결과를 AN(t)로 하고 상기 소정크랭크각의 n-1회 및 A 째에 상기 내연기관이 흡입하는 공기량이 상당하는 상기 AN검출수단의 출력상당치를 각각 AN(n-1) 및 AN(n)으로 하였을 경우에, 식 AN(n)=K x AN(n-1)+(1-K) x AN(t)에 의하여 AN(n)을 계산하는 AN연산수단고, 상기 AN(n)을 바탕으로하여 상기 내연기관에 공급 연료량을 제어하는 제어수단등을 구비한 내연기관의 연료제어장치에 있어서, AN(n-1)에 대하여 AN(t)가 소정치이상 저하한 것을 판정하는 판정수단을 설치하고, 상기 AN연산수단은 상기 판정수단의 판정을 받아서 상기AN(t)의 저감에 의한 AN(n)의 저감을 제어하도록 AN(n)을 연산하는 수단을 가진 것을 특징으로 하는 내연기관에 제어장치.
