Abstract

エンジン気筒間の固有の回転不均一を反映した各気筒の回転数調整を行うための燃料噴射量の補正手段を提供することを課題とする。複数の気筒を有し、各インジェクタ３の開弁時間を個別に制御可能なエンジン２において、各インジェクタ３のそれぞれの燃料噴射に伴うインジェクタ３に対応するそれぞれの気筒の個別基準回転数Ｎｓｔｄｉを出力する個別基準回転数出力ユニット３０と、各インジェクタ３のそれぞれの燃料噴射に伴うインジェクタ３に対応する各気筒の個別実回転数Ｎｉを検出するエンジン回転数センサー６と、個別基準回転数出力ユニット３０により記憶される個別基準回転数Ｎｓｔｄｉと前記エンジン回転数センサー６により算出される個別実回転数Ｎｉとの回転数差分に基づいて、該当する気筒のインジェクタ３からの燃料噴射量の補正量を算出する補正量算出ユニット５０と、を具備するコモンレール式ディーゼルエンジン１。
