Abstract

【課題】多段噴射を行なうディーゼルエンジンにおいて、冷態時から暖態時へ移行するときの白煙増加を改善するために、燃料を圧送する燃料供給ポンプ５３と、該燃料供給ポンプより圧送される燃料を蓄圧するコモンレール５２と、電子制御によって気筒内に燃料を噴射するインジェクタ５１と、エンジン冷却水温度を検出する冷却水温度センサー６４と、前記エンジン運転状態検出手段の出力から、目標コモンレール圧力、総噴射量、多段噴射量の回数、各噴射量、及び各噴射時期を算出する燃料噴射量マップと、からなる燃料噴射装置５０を有するディーゼルエンジン１０において、前記噴射制御量演算手段の総噴射量を増加させる総噴射量増加手段と、エンジンが冷態時から暖態時へ移行する際に、前記総噴射量増加手段によって前記多段噴射回数が変更されることを回避する噴射回数減少回避手段とを備えるディーゼルエンジン１０を提供する。
