Abstract
Description
I(t)≒{1−e-(R/L)t}E/R
となる。即ち、過渡現象として一次電流は逓増するが、その増加の速さは徐々に衰える。十分に長い時間が経過すると、図3中の破線のように一次電流はE/Rに飽和する。
1…気筒
12…点火プラグ
13…イグナイタ
14…点火コイル
32…スロットルバルブ
h…イオン電流信号
i…点火信号
Claims (2)
- 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い、しかる後同点火コイルに通電する電流を平時の大きさに戻すことを特徴とする火花点火式内燃機関の制御装置。 - 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、
スロットルバルブ開度の単位時間あたりの縮小量が所定値を超えたとき、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い、しかる後同点火コイルに通電する電流を平時の大きさに戻すことを特徴とする火花点火式内燃機関の制御装置。
