| description | PROBLEM TO BE SOLVED: To provide an exhaust emission control device of an engine capable of appropriately suppressing an emission amount of hydrocarbon, in a structure including an HC adsorption catalyst and an exhaust emission control catalyst provided on a downstream side thereof.SOLUTION: An exhaust emission control device of an engine includes a cooler 60 configured to cool an HC adsorption catalyst, and a cooling control unit 71 configured to operate the cooler at predetermined operation rate depending on a start state of the engine. The cooling control unit 71 comprises: a start state determination unit 72 configured to determine whether start of the engine originates from start in restoration of idling stop; and an operation rate adjustment unit 73 configured to, when the start state determination unit determines that start the engine originates from the start in restoration of idling stop, make an operation rate lower compared to a case where it is determined that the start of the engine does not originate from the start in restoration of idling stop.SELECTED DRAWING: Figure 3
【課題】ＨＣ吸着触媒とその下流側に設けられる排気浄化触媒とを備える構成において、炭化水素の車外への排出量を適切に抑制することができるエンジンの排気浄化装置を提供する。【解決手段】ＨＣ吸着触媒を冷却する冷却装置６０と、エンジンの始動状態に応じた所定稼働率で冷却装置を作動させる冷却制御部７１と、を備え、この冷却制御部７１が、エンジンの始動がアイドルストップ復帰時始動であるか否かを判定する始動状態判定部７２と、始動状態判定部によってエンジンの始動がアイドルストップ復帰時始動であると判定されると、エンジンの始動がアイドルストップ復帰時始動ではないと判定された場合に比べて稼働率を低い値とする稼働率調整部７３と、を含む構成とする。【選択図】図３ |
