Claims (1)
- 燃焼室に点火手段を備え、所定の運転領域で前記燃焼室に供給される混合気を圧縮着火燃焼させる圧縮着火運転を行うと共に、前記所定の運転領域以外の運転領域で前記点火手段を介して前記混合気を火花点火燃焼させる火花点火運転を行い、さらに前記火花点火運転をアトキンソンサイクルで行う圧縮着火内燃機関の制御装置において、前記火花点火運転がアトキンソンサイクルで行われているとき、圧縮着火運転に切り替えたと仮定したときの噴射燃料の壁面付着量を推定する壁面付着量推定手段と、前記推定された壁面付着量を用いて燃料噴射量を算出する燃料噴射量算出手段と、および前記算出された燃料噴射量が零あるいはその付近の値であるとき、前記火花点火運転から前記圧縮着火運転への切り替えを禁止する切り替え禁止手段とを備えたことを特徴とする圧縮着火内燃機関の制御装置。
