Claims (1)
- 点火コイルに通電後その通電を遮断することで点火コイルに発生する誘導電圧を点火プラグの電極に印加し、点火プラグにおける火花放電を惹起するものであって、
気筒における混合気の燃焼状態が悪化したとき、通電の遮断直前に点火コイルに通電する電流の大きさを平時よりも増大させる補正制御を行うとともに気筒に充填される吸気のEGR率を低下させる操作を行い、当該操作からタイムラグを持って吸気のEGR率が低下するのを待って同点火コイルに通電する電流を平時の大きさに戻す、
または、燃料カット条件が成立してから実際に燃料噴射を停止するまでの遅延時間中に、点火タイミングを遅角するとともに、通電の遮断直前に点火コイルに通電する電流の大きさを平時よりも増大させる補正制御を行い、燃料噴射の停止後、同点火コイルに通電する電流を平時の大きさに戻す火花点火式内燃機関の制御装置。
