Claims (6)
- 内燃機関の燃料噴射弁を操作することで燃料噴射制御を行う内燃機関の燃料噴射制御装置において、
前記内燃機関の吸気相当量を検出する検出手段による検出値を前記内燃機関の出力軸の所定の回転角度毎に都度取得する取得手段と、
前記吸気相当量の検出値に基づき、前記内燃機関の燃料噴射期間を設定する設定手段とを備え、
前記設定手段は、前記内燃機関の燃料噴射に先立つタイミングにおける前記検出値に基づき前記燃料噴射期間を設定する手段と、前記燃料噴射弁を介して燃料が噴射されているときにおける前記所定の回転角度毎に、前記検出値に応じて前記燃料噴射期間を変更する変更手段とを備えることを特徴とする内燃機関の燃料噴射制御装置。 - 前記変更手段は、前記燃料が噴射されているときにおける都度の前記検出値に基づき燃料噴射期間を算出する手段と、今回算出される燃料噴射期間とそれ以前に算出されている燃料噴射期間とを比較する比較手段と、該比較手段による比較対象が互いに一致しないとき、前記以前に算出されている燃料噴射期間を今回算出される燃料噴射期間で置き換える手段とを備えることを特徴とする請求項1記載の内燃機関の燃料噴射制御装置。
- 前記今回算出された燃料噴射期間によって定まる噴射終了タイミングに対して現在のタイミングが遅延しているとき、燃料噴射を直ちに終了する終了手段を更に備えることを特徴とする請求項2記載の内燃機関の燃料噴射制御装置。
- 前記吸気相当量が、前記内燃機関の吸気通路の流路面積を調節する吸気絞り弁によって調節された流路面積であることを特徴とする請求項1〜3のいずれかに記載の内燃機関の燃料噴射制御装置。
- 前記設定手段は、前記内燃機関の出力軸の回転速度及び前記流路面積と前記燃料噴射期間とを関係付ける関係情報に基づき、前記燃料噴射期間を設定することを特徴とする請求項4記載の内燃機関の燃料噴射制御装置。
- 請求項1〜5のいずれかに記載の燃料噴射制御装置と、
前記燃料噴射弁と、
前記検出手段とを備えることを特徴とする燃料噴射制御システム。
