Abstract

　建設機械の排気ガス浄化システムにおいて、フィルタに多量のＰＭが堆積される前にフィルタの再生を行うことで、再生直前の排気ガスの圧力上昇による出力の低下を回避し、かつ再生を行なった際のＰＭの燃焼によるフィルタ内部温度の異常上昇やそれに由来するフィルタの溶損を引起す可能性を低減する。 　事前に自動再生スイッチ３８ｂをＯＮ位置に操作しておき、ゲートロックレバー２２を第２位置Ｂに上げ操作してキースイッチ５をＯＦＦ位置に操作すると、コントローラ４は、差圧検出装置３６の検出値（フィルタ３２の前後差圧）が第２所定圧力Ｐ２よりも高い場合は、エンジン回転数を再生に適した所定の回転数Ｎａに制御した後、自動的に強制再生に入りＰＭを焼却除去する。差圧検出装置３６の検出値が第１所定圧力Ｐ１より低くなると自動的に再生を終了し、エンジン１を停止させる。
