- 少なくとも1回の水の噴射が、吸入行程の間に行われることを特徴とする、請求項1ないし5のいずれか1項に記載の操作方法。
- 少なくとも1回の水の噴射が、制御された自己点火(RZV)が開始する前に行われることを特徴とする、請求項1ないし6のいずれか1項に記載の操作方法。
- 排気ガスが保持される場合、少なくとも1回の水の噴射が、中間圧縮段階の間に行われることを特徴とする、請求項1ないし7のいずれか1項に記載の操作方法。
- 少なくとも1回の水の噴射が、前記各燃焼室内で支配的な前記圧力に依存して行われることを特徴とする、請求項1ないし8のいずれか1項に記載の操作方法。
- 少なくとも1回の水の噴射が、前記各燃焼室内で支配的な前記温度に依存して行われることを特徴とする、請求項1ないし9のいずれか1項に記載の操作方法。
- 前記RZV部分操作方法から前記NAV部分操作方法に切り替えるとき圧縮率εは低くなり、前記NAV部分操作方法から前記RZV部分操作方法に切り替えるとき前記圧縮率εは上昇することを特徴とする、請求項1ないし10のいずれか1項に記載の操作方法。
