Claims (3)
- 気筒の燃焼室内に生じる気流を操作するための流動制御装置を、気筒の燃焼室の天井部を形成する部位とピストンの頂面とのうちの少なくとも一方に設け、
エンジン回転数、エンジン負荷、または可変バルブタイミング機構が具現する吸気バルブ若しくは排気バルブの開閉タイミングに応じて、気筒の燃焼室内において吸気バルブ側に向かう気流を強めるか、排気バルブ側に向かう気流を強めるかを選択し、そのような気流を具現するべく前記流動制御装置を制御する内燃機関。 - 前記流動制御装置が、誘電体を挟んで対をなす電極を配置し、電極間に交流電圧またはパルス電圧を印加することで、誘電体の表面側の電極近傍にプラズマ及び気体の流れを生じさせるプラズマアクチュエータであり、
当該プラズマアクチュエータを、気筒の中心軸を挟むように、クランクシャフトの伸びる方向に沿って並べて設ける請求項1記載の内燃機関。 - ノッキングが起こりやすい運転領域では気筒の燃焼室内において排気バルブ側に向かう気流を強めるように前記流動制御装置を制御し、ノッキングが起こりにくい運転領域では気筒の燃焼室内において吸気バルブ側に向かう気流を強めるように流動制御装置を制御する請求項1記載の内燃機関。
