Claims (5)
- ターボチャージャを備えるとともに、このターボチャージャのコンプレッサの吸気通路における下流側にスロットル弁を備え、かつ、理論空燃比を目標空燃比としたストイキ燃焼モードとリーン空燃比を目標空燃比としたリーン燃焼モードとに切換可能な内燃機関の制御方法であって、
上記リーン燃焼モードから上記ストイキ燃焼モードに移行するときに、上記スロットル弁の開度を低下させるとともに、上記スロットル弁よりも吸気通路における下流側の位置に連通したエアバイパス弁を一時的に開いてコレクタ内の吸気を上記コンプレッサの上流側にバイパスさせる、内燃機関の制御方法。 - さらに、吸気通路における上記コンプレッサの下流側と上流側とを接続したリサーキュレーション通路に設けられたリサーキュレーションバルブを一時的に開いて、上記コンプレッサと上記スロットル弁との間の吸気を上記コンプレッサの上流側に戻す、請求項1に記載の内燃機関の制御方法。
- さらに、吸気弁の開閉時期もしくはリフト量の少なくとも一方を変更可能な可変動弁機構を、体積効率が低下する制御位置に一時的に制御する、請求項1または2に記載の内燃機関の制御方法。
- 上記リーン燃焼モードから上記ストイキ燃焼モードへの移行時に点火時期リタードを行う、請求項1〜3のいずれかに記載の内燃機関の制御方法。
- ターボチャージャを備えるとともに、このターボチャージャのコンプレッサの吸気通路における下流側にスロットル弁を備え、かつ、理論空燃比を目標空燃比としたストイキ燃焼モードとリーン空燃比を目標空燃比としたリーン燃焼モードとに切換可能な内燃機関において、
上記スロットル弁よりも吸気通路における下流側の位置から上記コンプレッサの上流側に至るエアバイパス通路と、このエアバイパス通路を開閉するエアバイパス弁と、コントローラと、を備え、
上記リーン燃焼モードから上記ストイキ燃焼モードに移行するときに、上記コントローラは、上記スロットル弁の開度を低下させるとともに、上記エアバイパス弁を一時的に開いてコレクタ内の吸気を上記コンプレッサの上流側にバイパスさせる、内燃機関。
