Abstract

【課題】高性能な排気浄化装置を備え、かつ運転室温度を速やかに快適温度まで昇温可能なエンジン動力機械を提供する。 【解決手段】脱硝触媒３と還元剤とを用いる排気浄化装置に、エンジン冷却媒体の熱により還元剤タンク５内に貯蔵された還元剤を加熱する還元剤加熱装置１３と、還元剤加熱装置１３へのエンジン冷却媒体の導入を制御する開閉装置１４とを備える。コントローラ１５は、エンジン冷却媒体の温度が第１の所定温度よりも高く、タンク５内の還元剤の温度が第２の所定温度よりも低く、運転室７内の温度が第３の所定温度よりも低い場合、開閉装置１４を閉止状態に切り換え、暖房装置８の熱交換器８ａに導かれるエンジン冷却媒体の流量を増加する。これにより、寒冷時に運転室７を優先的に暖房できるので、運転者の快適性を高めることができる。
