- 燃焼室内に直接燃料を噴射する燃料噴射弁と、ピストンの上死点位置を変更して内燃機関の圧縮比を変更可能な可変圧縮比機構と、を有し、
車両の走行中に所定の燃料カット条件が成立すると上記燃料噴射弁からの燃料噴射を中止する燃料カットを実施し、
上記燃料カット中に所定の燃料カットリカバー条件が成立すると、上記燃料噴射弁からの燃料噴射を再開する内燃機関の制御装置において、
上記燃料カットからの燃料噴射再開時の圧縮比は、燃焼室の壁面の温度が低くなるほど、上記燃料噴射弁から筒内に噴射された燃料の上記ピストンへの付着を低減するよう、運転状態に応じて決定される通常時圧縮比よりも低くするものであって、
上記燃料カットからの燃料噴射再開時に上記燃料噴射弁からの燃料噴射量を一時的に増量するリッチスパイクを実施し、上記リッチスパイクの終了後に、圧縮比を上記通常時圧縮比に戻す内燃機関の制御装置。 - 内燃機関の圧縮比を上記燃料カット中に予め低下させる請求項1に記載の内燃機関の制御装置。
- 上記燃料カットからの燃料噴射再開時の圧縮比は、上記燃料カットの期間が長くなるほど上記通常時圧縮比よりも低くする請求項1または2に記載の内燃機関の制御装置。
- 上記燃料カットからの燃料噴射再開時の燃料噴射時期は、燃料噴射再開時に設定される圧縮比が上記通常時圧縮比よりも低くなるほど進角させる請求項1〜3のいずれかに記載の内燃機関の制御装置。
- 上記燃料カットからの燃料噴射再開時の圧縮比は、燃料カットリカバー条件が成立した際の機関回転数が低くなるほど低くする請求項1〜4のいずれかに記載の内燃機関の制御装置。
- 上記燃料カットからの燃料噴射再開時の圧縮比は、燃料カットリカバー条件が成立した際の機関負荷が高くなるほど低くする請求項1〜5のいずれかに記載の内燃機関の制御装置。
