Claims (3)

  1. 엔진의 연료분사량을 제어하는 엔진제어 장치에 있어서, 분사한 연료중 연료흡기관 벽면에 부착한 액막량과, 액막에서 증발한 연료중 실린더에 흡입되는 일없이 흡기관내에 잔류하는 증기연료량을 추정하고, 이 추정치에서 공연비를 제어파라미터로서 포함하는 연료계모델을 사용하여 소망의 시각에 있어서의 액막량과 증기연료량을 예측하며, 이 예측결과에 의해 상기 공연비가 이론 공연비가 되도록 연료분사량을 제어하는 것을 특징으로 하는 엔진의 연료분사 제어방법.
  2. 엔진의 연료분사량을 제어하는 엔진제어 장치에 있어서, 분사한 연료중 연료흡기관 벽면에 부착한 액막량을 추정하며, 이 추정치에서 관측지연 시간을 갖는 공연비 및 엔진회전수를 제어파라미터로서 포함하는 연료계모델을 사용하여 소망의 시각에 있어서의 액막에서 증발하는 양과 흡기관 벽면에 부착하지 않는 연료량과의 합을 예측하고, 예측된 합에 해당하는 연료량이 실린더에 흡입되는 것으로 하여 상기 공연비가 이론공연비로 되도록 연료분사량을 제어하는 것을 특징으로 하는 엔진의 연료분사 제어방법.
  3. 상기 관측지연 시간은 엔진회전수에서 산출되는 것을 특징으로 하는 특허청구의 범위 2기재의 연료분사 제어방법.
