- 前記点火時点(ZZP)のシフトを制御し、その際に前記内燃エンジン(1)の前記回転数(n)が変化しないように前記点火時点(ZZP)を制御することを特徴とする、請求項1から6までのいずれか一つに記載の作動方法。
- 前記燃料供給量(x)を減少させ、前記点火時点(ZZP)を「遅」のほうへシフトさせることを特徴とする、請求項1から7までのいずれか一つに記載の作動方法。
- 前記燃料供給量(x)を増大させ、前記点火時点(ZZP)を「早」のほうへシフトさせることを特徴とする、請求項1から7までのいずれか一つに記載の作動方法。
- まず、燃料供給量(x)を変化させ、前記クランク軸(20)の所定回転回数にわたって前記点火時点(ZZP)を「遅」のほうへ変化させることを特徴とする、請求項1から9までのいずれか一つに記載の作動方法。
