Description
この場合、優先的に全気筒の吸気弁の弁体の作動状態が一度で切り替えられるので、フューエルカット制御の開始時に閉弁の遅れた吸気弁から不要な空気が気筒内に進入することを避けることができる。このことは、全気筒の吸気弁の弁体の作動状態の切り替えと全気筒の燃料供給停止とを一度に行うフューエルカット制御の即時実施の実行頻度を向上させる。従って、この内燃機関制御装置によれば、フューエルカット制御の即時実施の実行頻度を向上させることで、内燃機関の燃費向上を図ることができる。
第1の実施形態に係る内燃機関制御装置1は、車両に備えられた4気筒のレシプロエンジン(内燃機関)を制御するものである。内燃機関制御装置1は、所定のフューエルカット条件が成立した場合に、4気筒全ての燃料供給を停止するフューエルカット制御を実施する。内燃機関制御装置1が制御するレシプロエンジンには、気筒の吸気弁及び排気弁の開閉タイミングやリフト量を可変とする可変バルブ機構と、気筒から排出された排気ガスの一部を吸気側に戻すEGR[Exhaust Gas Recirculation]と、が備えられている。
第2の実施形態に係る内燃機関制御装置20は、第1の実施形態に係る内燃機関制御装置1と比較して、VVT[Variable Valve Timing]ソレノイド17及びスロットルアクチュエータ18を備える点と、駆動制御部34の機能と、が主に相違する。
Claims (2)
- 吸気弁及び排気弁を有する複数の気筒を備える内燃機関を制御する内燃機関制御装置であって、
前記吸気弁又は前記排気弁の弁体の作動状態を駆動状態と閉弁保持状態とに切り替える切替ユニットと、
前記切替ユニットを制御する制御ユニットと、
前記制御ユニットの温度を検出する温度検出ユニットと、
前記温度検出ユニットの検出した前記温度が高いほど、前記切替ユニットが一度に作動状態を切り替える前記弁体の数を少なく設定する切替数設定ユニットと、
を備えることを特徴とする内燃機関制御装置。 - 前記制御ユニットは、前記切替数設定ユニットが設定した前記弁体の数が全気筒の前記吸気弁の数以上である場合、全気筒の前記吸気弁の弁体の前記作動状態を一度に切り替えるように前記切替ユニットを制御することを特徴とする請求項1に記載の内燃機関制御装置。
