Claims (3)
- 内燃機関の吸気通路内に燃料を噴射する燃料噴射手段と、1サイクルあたりに噴射すべき燃料を前記内燃機関の吸気弁の開弁前に終了する非同期噴射と前記吸気弁の開弁中に終了する同期噴射とに分割して前記燃料噴射手段が噴射するように前記燃料噴射手段を制御する燃料噴射制御手段と、前記吸気通路の壁面温度又はその温度と相関する物理量を取得する取得手段と、前記非同期噴射と前記同期噴射との噴射配分を設定する噴射配分設定手段と、を備え、
前記噴射配分設定手段は、未燃燃料の排出量の最小値を与える前記噴射配分を前記取得手段にて取得された前記壁面温度又は前記物理量に応じて設定することを特徴とする内燃機関の制御装置。 - 前記噴射配分設定手段は、前記壁面温度又は前記物理量が大なる場合は小なる場合に比べて、前記非同期噴射の占める割合が大きくなるように前記噴射配分を設定することを特徴とする請求項1に記載の内燃機関の制御装置。
- 前記壁面温度又は前記物理量が所定範囲内にあるか否かを判定する判定手段を備え、
前記燃料噴射制御手段は、前記判定手段が前記壁面温度又は前記物理量が前記所定範囲内にあると判定した場合、1サイクルあたりに噴射すべき燃料を前記非同期噴射と前記同期噴射とに分割して前記燃料噴射手段が噴射し、かつ前記判定手段が前記壁面温度又は前記物理量が前記所定範囲外にあると判定した場合、1サイクルあたりに噴射すべき燃料を前記非同期噴射又は前記同期噴射のいずれか一方にて前記燃料噴射手段が噴射するように前記燃料噴射手段を制御することを特徴とする請求項1又は2に記載の内燃機関の制御装置。
