Abstract
【解決手段】排気管3の途中に装備されて酸素共存下でも選択的にNOxをアンモニアと反応させ得る選択還元型触媒4と、該選択還元型触媒4より上流側の排気管3内に還元剤として尿素水6を添加する尿素水インジェクタ5と、該尿素水インジェクタ5に尿素水供給ライン8を介し尿素水6を供給する尿素水タンク7とを備えた排気浄化装置に関し、前記尿素水タンク7を経由し且つ前記尿素水供給ライン8に沿うように冷却水ライン16を設け、該冷却水ライン16に対しエンジン1側の水冷式オイルクーラ17から冷却水18を抜き出して前記冷却水ライン16を経由させた後にエンジン1側のウォーターポンプ19に戻すように構成する。

- 排気管の途中に装備されて酸素共存下でも選択的にNOxをアンモニアと反応させ得る選択還元型触媒と、該選択還元型触媒より上流側の排気管内に還元剤として尿素水を添加する尿素水インジェクタと、該尿素水インジェクタに尿素水供給ラインを介し尿素水を供給する尿素水タンクとを備えた排気浄化装置であって、前記尿素水タンク内を経由し且つ前記尿素水供給ラインに沿うように冷却水ラインを設け、該冷却水ラインに対しエンジン側の水冷式オイルクーラから冷却水を抜き出して前記冷却水ラインを経由させた後にエンジン側のウォーターポンプに戻すように構成したことを特徴とする排気浄化装置。
- 冷却水ラインの尿素水タンクより上流側から分岐して尿素水インジェクタを経由し且つ前記冷却水ラインにおける尿素水供給ラインに沿い終えた後の下流部分に合流するようにバイパスラインを設け、該バイパスラインに冷却水の流れを切り替え得るように流路切替手段を備えたことを特徴とする請求項1に記載の排気浄化装置。
