Claims (3)
- 機関の負荷及び回転数に応じて予め規定された成層燃焼領域及び均質燃焼領域において、それぞれ成層燃焼制御及び均質燃焼制御を実行する制御手段を備えたガス燃料エンジンにおいて、
前記機関からの排気経路中に設けられたNOx浄化触媒の劣化状態を検出する劣化検出手段と、
機関の負荷及び回転数が前記成層燃焼領域内の均質燃焼領域に隣接する所定領域にある場合には、燃料と空気との混合時間が延長化されるように、前記劣化検出手段が検出した劣化状態に応じて、前記機関の燃料噴射時期と点火時期との間隔を補正する補正手段と
を有することを特徴とするガス燃料エンジン。 - 請求項1に記載のガス燃料エンジンであって、
前記補正が、前記燃料噴射時期の通常値に対する変更によって行われることを特徴とするガス燃料エンジン。 - 請求項1または2に記載のガス燃料エンジンであって、
前記補正手段による補正量を所定値以内に制限する補正制限手段を更に備えたことを特徴とするガス燃料エンジン。
