Abstract

油圧ショベル等の走行式の作業車両において、排気ガス中に含まれる粒子状物質を捕集するためのフィルタの手動再生制御と作業系の動作が互いに影響することのない適切な状態で手動再生制御を行うことができる作業車両の排気ガス浄化システムを提供する。 　再生用燃料噴射装置４０の作動（手動再生制御）の開始を、手動再生開始スイッチ３９が操作され、エンジンコントロールダイヤル２がローアイドルを指令するよう操作され、かつゲートロックレバー２２がリモコン弁２５，２６，２７による制御パイロット圧ａ～ｆの生成を不能とする第２位置Ｂに操作されたときに行う。手動再生制御中であっても、ゲートロックレバー２２が第１位置Ａに操作されると、直ちに手動再生制御を終了する。
