Description
(1)ホイールローダは、エンジン301の排気ガスを処理する選択触媒還元装置430、および選択触媒還元装置430へ供給される排気ガス中に尿素水を噴射する還元剤噴射装置420を有する排気ガス浄化装置400を備えている。ホイールローダは、エンジン301および排気ガス浄化装置400を収容するエンジン室122Eを画成する建屋122を備えている。建屋122は、エンジン301の上方でエンジン室122Eを覆う天板を構成するエンジンフード140と、エンジンフード140に設けられ、エンジン室122E内の空気をエンジン室122Eの外部に排出する排気ダクト149と、を有している。還元剤噴射装置420には、尿素水を導く還元剤供給配管425sが接続されている。還元剤噴射装置420から上方に延びる還元剤供給配管425sの一部(頂部TP)は、還元剤噴射装置420の上方位置における排気ダクト149内に配置されている。
(変形例1)
上述した実施の形態では、ホースのみによって第1供給配管435sを構成する例について説明したが、本発明はこれに限定されない。図10の二点鎖線で示すように、ホースに貯留部900を介装して、第1供給配管435sをホースと貯留部900を含んで構成してもよい。貯留部900は、ホースの流路断面積よりも大きい流路断面積を有し、冷却水の容積を拡大するために設けられている。貯留部900を排気ダクト149に配置することで、貯留部900内の冷却水を効果的に冷却できる。
上述した実施の形態では、冷却水循環システムが尿素水の温度上昇を抑制するために設けられていることについて説明したが、凍結した尿素水を解凍するのに利用してもよい。冬季や寒冷地でクレーン作業を行う際、尿素水が凍結していると、還元剤噴射装置420に尿素水を供給できない。このため、還元剤噴射装置420を使用するには、凍結した尿素水を解凍し、さらに解凍した尿素水が再び凍結することを防止する必要がある。そこで、エンジン301と熱交換することで暖められた冷却水を噴射弁429や尿素水タンク127に導くことで、噴射弁429や尿素水タンク127内における凍結した尿素水を解凍し、解凍された尿素水が再び凍結することを防止することができる。
上述した実施の形態では、還元剤として尿素水溶液を用いた例について説明したが、本発明はこれに限定されない。アンモニア水溶液など種々の還元剤を利用した排気ガス浄化装置400を備える作業機械に本発明を適用することができる。
上述した実施の形態では、ホイールローダに本発明を適用した例について説明したが、本発明はこれに限定されることなく、油圧ショベルやクレーンなど、種々の作業機械に適用することができる。
