Claims (1)
- アクセルペダルの踏込量及びエンジン回転数に応じて吸気通路を気筒に向けて流れる新気の流量の目標値を決定し、吸気通路に設置しているエアフローメータを介して検出される新気流量と当該目標値との偏差を縮小するようにスロットルバルブの開度を操作し、
エアフローメータを介して検出される新気流量に応じて吸気バルブまたは排気バルブの開閉タイミングを決定し、その開閉タイミングを実現するように吸気バルブまたは排気バルブを操作し、
エアフローメータを介して検出される新気流量、エンジン回転数、並びに、吸気バルブまたは排気バルブの開閉タイミングに応じて気筒に充填されるべき吸気の圧力の目標値を決定し、吸気通路に設置している吸気圧センサを介して検出される吸気圧と当該目標値との偏差を縮小するようにEGRバルブの開度を操作する内燃機関の制御装置。
