を備えるものである。
[実施の形態1の構成]
図1は、本発明の実施の形態1のシステム構成を説明するための模式図である。本実施形態のシステムは、制御装置の適用対象となる火花点火式の内燃機関2を備えている。内燃機関2はガソリンを燃料とするものであり、例えば、車両の動力源として好ましく使用することができる。内燃機関2は、空燃比が理論空燃比(以下「ストイキ」)近傍の混合気を燃焼させるストイキ燃焼運転と、所定のリーン燃焼運転領域で理論空燃比より大幅にリーンな空燃比の混合気を燃焼させるリーン燃焼運転と、を切り替えて行うことができる。また、図1では、内燃機関2の1つの気筒のみを図示しているが、内燃機関2は複数の気筒を備えている。内燃機関2の気筒数および気筒配置は特に限定されるものではない。
本実施の形態において制御装置が実行する制御には、ISC弁34の開閉状態に関する制御が含まれる。この制御において、制御装置は要求トルクと、内燃機関で発生し得るトルクである予想発生トルク(推定トルクとも称する)とを取得する。要求トルクと予想発生トルクとは既知の手法により演算され、ここではその演算手法は限定されない。また、要求トルクと予想発生トルクとは、本実施の形態における制御装置が直接的に演算するものに限らず、制御装置の上位に配置されたシステムより入力されるものであってもよい。
ところで、本実施の形態の内燃機関2はリーン燃焼運転が可能な内燃機関である。このようなリーン燃焼運転可能な内燃機関の場合、リーン燃焼を安定して行うために吸気ポート形状が最適化され、筒内に発生するスワール流やタンブル流を強化するように設計されている。しかし、ISC弁全開制御の実行中は、ISC通路32を介して吸気が上流側に逆流する。このためISC弁全開制御中は、吸気通路12内での吸気の流れも大きく変化する。その結果、筒内に発生するスワール流やタンブル流が不足し、特に、リーン燃焼限界が低下し、あるいは、リーン燃焼が不安定となることが考えられる。
更に、本実施の形態の制御装置は、リーン燃焼運転時には、ISC弁全開制御を禁止する。つまり、リーン燃焼運転が行われている時には、ISC弁全開条件が成立するような運転状態であっても、ISC弁全開制御が行われない。
