Description
ここで「オーバラップ期間を増加させる」とは、電動機によるコンプレッサの駆動補助を開始する時点のオーバラップ期間が「0」より大きい状態から増加させる場合と、オーバラップ期間が「0」以下の値である状態から増加させる場合とを含むものとする。
機関回転数が比較的低くかつ吸気圧が目標過給圧より低い運転状態で電動機による駆動補助を行うことにより、吸気圧の上昇を早めて過給機の応答性改善効果及び掃気促進効果を得ることができる。
図1は本発明の一実施形態にかかる内燃機関の構成を模式的に示す図である。内燃機関(以下「エンジン」という)1は、4つの気筒6を有し、気筒6の燃焼室内に燃料を直接噴射する直噴エンジンであり、各気筒6には燃料噴射弁7、点火プラグ8、及び吸気弁及び排気弁(図示せず)が設けられている。
弁作動位相可変機構20は、各気筒6の吸気弁及び排気弁の作動位相を変更する機構である。
なお、図3では、リフト量LFTが基準リフト量LFT0より大きい状態を開弁状態として、開閉弁時期を示している。
CAIN0<CAIN1<CAIN2<CAIN3<CAIN3a<CAIN4<CAIN5
すなわち、推定出力トルクTRQHが大きい高負荷領域では、第1CAINマップの設定値の方が第2CAINマップの設定値より大きく、オーバラップ期間TCAOVLが増加するように設定されている。
CAEX0<CAEX1<CAEX2<CAEX3<CAEX4
すなわち、推定出力トルクTRQHが大きい高負荷領域では、第1CAEXマップの設定値の方が第2CAEXマップの設定値より大きく、オーバラップ期間TCAOVLが増加するように設定されている。
