Claims (1)
- 気筒に連なる吸気ポートに向けてインジェクタから燃料を噴射するポート噴射式の内燃機関を制御するものであって、
内燃機関の始動の完了後、内燃機関の温度が上昇して閾値に到達する前の時期にあっては、インジェクタからの燃料噴射を終了するタイミングを気筒の吸気バルブが開弁した後所定のクランク角度が経過したタイミングとし、内燃機関の温度が閾値に到達した後には、インジェクタからの燃料噴射を終了するタイミングをより早めることとし、
内燃機関の始動のためのクランキング中の所定時間内にエンジン回転数がある値まで上昇しなかった場合、そうでない場合と比較して、その後の燃料噴射量を増量補正し、かつ前記閾値をより高く設定し、
さらに、燃料の温度が低い場合、燃料の温度が高い場合と比較して、前記閾値をより高く設定する内燃機関の制御装置。
