Claims (5)

  1. 筒内に燃料を噴射するための第1の燃料噴射手段と吸気通路内に燃料を噴射するための第2の燃料噴射手段とを備えた内燃機関の制御装置であって、
    前記内燃機関に要求される条件に基づいて、前記第1の燃料噴射手段と前記第2の燃料噴射手段とで分担して燃料を噴射するように、燃料噴射手段を制御するための制御手段と、
    前記内燃機関の潤滑に用いられる潤滑油が燃料により希釈された度合いを推定するための希釈度合推定手段とを含み、
    前記制御手段は、前記度合いが大きいと推定された場合には、前記度合いを抑制するように、かつ内燃機関に要求される性能を満足させるように、燃料噴射手段を制御するための手段を含み、
    前記制御手段は、前記第1の燃料噴射手段の燃料噴射制御の変更により、要求燃料噴射量に対して、不足分が生じる場合には、前記不足分を補うように前記第2の燃料噴射手段を制御するための手段を含む、内燃機関の制御装置。
  2. 前記制御手段は、前記第1の燃料噴射手段へ供給される燃料の圧力を低下させて、噴霧貫徹力を低下させるように、前記第1の燃料噴射手段を制御するための手段を含む、請求項1に記載の内燃機関の制御装置。
  3. 前記制御手段は、前記第1の燃料噴射手段の燃料噴射時期および燃料噴射期間の少なくとも一方を変更して、気筒内周面に前記第1の燃料噴射手段から噴射された燃料が当たらないように、前記第1の燃料噴射手段を制御するための手段を含む、請求項1に記載の内燃機関の制御装置。
  4. 前記制御手段は、前記内燃機関のピストンの位置と前記第1の燃料噴射手段による燃料噴射方向とに基づいて、気筒内周面に前記第1の燃料噴射手段から噴射された燃料が当たらないように、前記第1の燃料噴射手段を制御するための手段を含む、請求項3に記載の内燃機関の制御装置。
  5. 前記第1の燃料噴射手段は、筒内噴射用インジェクタであって、
    前記第2の燃料噴射手段は、吸気通路用インジェクタである、請求項1〜4のいずれかに記載の内燃機関の制御装置。
