Title (EN) EXHAUST PURIFICATION DEVICE
(FR) DISPOSITIF DE PURIFICATION D'ÉCHAPPEMENT
(JA) 排気浄化装置
Abstract:
(EN) This exhaust purification device includes a control device for executing a first regeneration process for regenerating a DPF or a second regeneration process for regenerating a reduction catalyst, on the basis of a comparison between threshold values corresponding to the amount of sulfur poisoning in an SCR catalyst and the amount of PM sediment of the DPF. The control device is configured so as to switch from the first regeneration process to the second regeneration process when, during the execution of the first regeneration process, the amount of PM sediment is less than a predetermined threshold value.
(FR) La présente invention concerne un dispositif de purification d'échappement qui comprend un dispositif de commande destiné à exécuter un premier processus de régénération pour régénérer un DPF ou un second processus de régénération pour régénérer un catalyseur de réduction, sur la base d'une comparaison entre des valeurs de seuil correspondant à la quantité d'empoisonnement au soufre dans un catalyseur SCR et à la quantité de sédiment PM du DPF. Le dispositif de commande est configuré de sorte à passer du premier processus de régénération au second processus de régénération lorsque, pendant l'exécution du premier processus de régénération, la quantité de sédiment PM est inférieure à une valeur seuil prédéterminée.
(JA) 排気浄化装置は、SCR触媒の硫黄被毒量及びDPFのPM堆積量と、それぞれに対応する閾値との比較に基づいて、DPFを再生する第1の再生処理又は還元触媒を再生する第2の再生処理を実行する制御装置を含む。また、制御装置は、第1の再生処理の実行中、PM堆積量が所定閾値未満となったときに、第1の再生処理から第2の再生処理に切り替えるように構成されている。
