Claims (1)
- エンジンの排気管に設けられた選択還元触媒装置と、
前記選択還元触媒装置の上流側で尿素水を噴射するドージングバルブと、
排気ガス中のNOx濃度を検出するNOxセンサと、
前記NOxセンサで検出されたNOx濃度に応じて尿素水噴射を制御する尿素水噴射制御部と、
エンジン回転数があらかじめ設定された下限値を超えており、かつ、車速があらかじめ設定された下限値を超えているときに、バッテリ電圧を診断し、バッテリ電圧が下限電圧以上であれば、適正電圧であると判定し、バッテリ電圧が前記下限電圧未満であれば、適正電圧でないと判定するバッテリ電圧診断部と、
を備えるSCRシステムであって、
前記下限電圧は、前記SCRシステムが正常に作動できる電圧に設定されていることを特徴とするSCRシステム。
