Claims (2)
- 内燃機関の吸気通路に燃料を噴射する燃料噴射弁と、
内燃機関の吸気通路に設けられた吸気バルブと、
前記吸気バルブの開閉タイミングを可変する可変動弁手段と、
機関回転数を取得する機関回転数取得手段と、
前記機関回転数、前記燃料の噴射時間及び前記吸気バルブの開弁タイミングに基いて、前記吸気バルブが閉じた状態で燃料が噴射される吸気非同期の時間と、前記吸気バルブが開いた状態で燃料が噴射される吸気同期の時間との比率が一定となるように前記燃料噴射弁からの燃料の噴射開始時期を算出する算出手段と、
前記噴射開始時期が算出されてから前記吸気バルブの開弁タイミングが到来するまでの間に、前記機関回転数取得手段により機関回転数を新たに取得し、少なくとも当該機関回転数に基いて前記比率が一定となるように前記吸気バルブの開弁タイミングを補正する補正手段と、
を備えたことを特徴とする内燃機関システム。 - 前記補正手段は、新たに取得した機関回転数と、当該機関回転数を取得した時期と、前記噴射開始時期と、前記燃料の噴射時間と、前記比率の値とに基いて前記吸気バルブの開弁タイミングを補正する構成としてなる請求項1記載の内燃機関システム。
