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。
