Claims (1)
- 筒内噴射式内燃機関の排気ガス浄化用の触媒を早期に暖機するために、点火時期及びシリンダ内への燃料噴射開始時期を遅角させる触媒暖機制御を行う内燃機関の制御装置であって、
前記触媒暖機制御を行って、内燃機関の始動時または前記触媒暖機制御開始時からの積算吸気量が第1所定値以上になる、触媒の暖機状態に関する第1所定条件が成立した場合は、点火時期を徐々に進角させるとともにシリンダ内への燃料噴射開始時期を徐々に進角させる徐変制御を行い、
前記徐変制御を行うときは、シリンダ内への燃料噴射開始時期から点火時期までのクランク角度が所定範囲内となるように、点火時期及びシリンダ内への燃料噴射開始時期を徐々に進角させ、
前記徐変制御を行って、前記積算吸気量が前記第1所定値よりも大きい第2所定値以上になる、触媒の暖機状態に関する第2所定条件が成立した場合は、前記徐変制御を終了することを特徴とする内燃機関の制御装置。
