Abstract

ポンプや発電機駆動用エンジンのように負荷増加状態が回転数の加速状態で現れないエンジンにおいて、ＥＧＲ量抑制又は中断によって急激な負荷増加状態におけるスモーク発生の防止を課題とする。過給機１１及び排気ガス再循環（ＥＧＲ）装置１２を備え、エンジン１０の回転数Ｎを無負荷（アイドル）又は軽負荷運転から高負荷（負荷増加）状態に移行したときに、アイソクロナス制御、又はドループ制御を行なうエンジン１０において、負荷状態へ移行したときに実回転数Ｎが目標回転数Ｎｍよりも所定回転数ΔＮよりも低下したことを検知した場合には、ＥＧＲ装置１２のＥＧＲ弁１３を負荷状態に対応する通常の設定開度Ｆよりも所定開度分ΔＦだけ小さい開度まで絞る、或いはＥＧＲ弁１３を全閉とする。
