Abstract
Description
まず、本願の発明者等は、前記課題の解決手段を検討し、気筒休止システムを備えた内燃機関において、バルブが作動状態と非作動状態とで燃焼室の圧力や流動に差があることに着目し、この差が燃焼室に配設された点火プラグによる点火放電の状態である点火放電時間に関係することを実験により得た(図6参照)。
Claims (5)
- 内燃機関の少なくとも一つの気筒を運転または休止させる気筒休止制御手段と、
前記気筒休止制御手段からの要求に基づいて、内燃機関に配設された吸気バルブおよび排気バルブの少なくともどちらか一方を作動もしくは非作動させるバルブ作動手段と、
予め設定される点火時期と通電時間に基づいて前記内燃機関に配設された点火コイルに通電し、前記内燃機関の燃焼室に配設された点火プラグを点火放電させる点火制御手段と、
前記点火放電の継続時間である点火放電時間を算出する点火放電時間算出手段と、
