Claims (1)

  1. V형엔진에 있어서의 흡입공기량보정을 주요파라미터로 하고, 이 정보에 따라 상기 엔진을 소정의 공연비로 제어하기 위한 기본연료량을 계산해서 흡기관에 부착된 인젝터로 연료공급지령신호를 출력하는 수단과, 좌우의 배기뱅크의 각각에 설치된 O2센서의 출력정보에 의해, 상기 엔진의 이론공연비로 운전될 수 있도록 상기 인젝터으로의 공급연료량을 보정하는 공연비피드백보정수단과, 각 배기뱅크마다의 피드백보정량의 중심치로부터의 편차를 학습하는 학습수단을 갖춘 장치에 있어서, 상기 O2센서의 한쪽의 이상동작을 검출하였을 경우에 정상동작을 행하는 다른 쪽의 O2센서의 출력정보와 양 쪽의 O2센서가 정상동작시에 있을 때의 학습치에 따라 연료량의 보정을 행하도록 한 것을 특징으로 하는 엔진의 공연비제어장치.
