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。
J=X+Uσ
として求められる。上式における係数Uは、そのときの運転領域、即ちエンジン回転数及びアクセル開度(または、サージタンク33内吸気圧(新気の分圧であることがある)、気筒1に充填される吸気量(新気量であることがある)、燃料噴射量)に応じて設定する。係数Uを、空燃比の高低や要求EGR率等に応じて変えるようにしてもよい。ノック判定値は、各気筒1毎に個別に求めてもよいし、全気筒1で共通のものとしてもよい。

Claims (2)
- 気筒に設置した点火プラグにおいて火花放電を惹起して気筒内の混合気に点火する火花点火式内燃機関を制御するものであって、
点火プラグにデポジットが堆積したことを感知した場合、気筒に充填された混合気に火花点火するために点火プラグに入力する電気エネルギの大きさを、デポジットの堆積を感知していない平常時における気筒内の混合気への点火のために点火プラグに入力する電気エネルギよりも増大させた上で火花放電を惹起するクリーニング処理を実行するとともに、
そのときの点火プラグの温度が低い状態ほど、前記クリーニング処理において点火プラグに入力する電気エネルギを大きくする内燃機関の制御装置。 - 前記クリーニング処理を実行する期間の長さを、点火プラグのくすぶりの度合いに応じて可変とする請求項1記載の内燃機関の制御装置。
