Abstract
Description
尿素水溶液は約−11℃で凍結するため、特許文献1に記載されるように、エンジン停止後において、噴射ノズルや還元剤供給流路の残留尿素水溶液の凍結変化を監視するとともに、その凍結変化に伴い噴射ノズルを一時的に開くことで、残留尿素水溶液を排気管内に放出する技術が知られている。
図1は、排気中の粒子状物質(PM:Particulate Matter)及びNOxを浄化する排気浄化装置の一例を示す。
尿素選択還元触媒コンバータシステム225は、尿素水溶液から生成されるアンモニアを還元剤として使用してNOxを選択還元浄化する選択還元触媒コンバータ210、選択還元触媒コンバータ210を通過したアンモニアを酸化させる酸化触媒コンバータ220と、を有する。
図3は、図2の筐体300の上方からみた、別の還元剤循環流路256のレイアウトを示す。図3の還元剤循環流路256も、筐体300の下面、側面を構成する熱交換板を這うように配置されてもよい。
また、図4に示すように、還元剤循環流路256は、排気管180周りにらせん状に配置されてもよい。
流路切換弁246については、図5(及び図6、図7)により説明する。流路切換弁246は、第1のロータリーバルブ247と、第1のロータリーバルブ247の内側に配置される第2のロータリーバルブ248と、で構成される。第1のロータリーバルブ247及び第2のロータリーバルブ248は、アクチュエータなどの既存の方法により、DCU270により回動制御される。
第1の回動位置(図5及び図6)では、外気導入流路254を閉止し、上流側還元剤供給流路250と下流側還元剤供給流路251と還元剤循環流路256との3者を連通可能とする。
また、第2の回動位置(図7)では、下流側還元剤供給流路251を閉止し、外気導入流路254と還元剤循環流路256と上流側還元剤供給通路256との3者を連通可能とする。
第2のロータリーバルブ248の回動位置B(図6)は、第1のロータリーバルブ247の第1の回動位置と組み合わせて用いられ、下流側還元剤供給通路251を閉止し、上流側還元剤供給通路250と還元剤循環通路256のみを連通させる(還元剤循環モード)。
第2のロータリーバルブ248の回動位置C(図7)は、第1のロータリーバルブ247の第2の回動位置と組み合わせて用いられ、上流側還元剤供給通路250を閉止し、外気導入通路254と還元剤循環流路256のみを連通させる(パージモード)。
ここで、ステップ2の尿素水循環モードと、ステップ3の尿素水添加モードを実行する所定時間について説明すると、本実施形態においては、尿素水溶液が完全に凍結しているときには、長時間尿素水循環モードを持続させることで、尿素水溶液の解凍を行い、尿素水溶液が解凍されるに従い、尿素水循環モードの時間を減少させ、一方、尿素水添加モードの時間を増加させる。尿素水溶液の解凍状況は、尿素水溶液温度センサ265から判定してもよいし、又は、尿素水循環モードの適用時間から推定して判定してもよい。
