Abstract

본 발명은 내연기관의 밸브를 통해 유동하는 가스 체적을 계산하기 위한 방법 및 장치에 관한 것이다.
도관을 통해 내연기관의 흡입관에 연결된 밸브를 통과하여 유동하는 가스 체적을 흡입관 내의 압력(p_SAUG) 및 대기압(p_AMB)의 함수로 결정하기 위한 방법은 대기압(p_AMB)이 알려져 있지 않은 경우에, 트로틀 밸브 각도(α)가 기록되는 단계와 가스 체적 유량이 상기 트로틀 밸브 각도(α)의 함수로 결정되는 단계로서 절차가 수행되는 것을 특징으로 하는 것이다.
상기 방법은, 흡입관 압력 및 대기압이 측정될 필요가 없을 뿐만 아니라 사실상 거의 모든 내연기관에서 기록되는 트로틀 밸브 부하 신호를 이용할 수 있다는 장점을 가진다.
