Abstract
【解決手段】 前記エンジン1により加熱される冷却水の通路の一部を前記尿素水タンク6に導いて、該尿素水タンク6内に貯蔵された尿素水の凍結防止又は凍結した尿素水の解凍をする冷却水循環配管8と、該冷却水循環配管8の途中に設けられ、該冷却水循環配管8の通路を開閉して冷却水の循環及び循環停止をする冷却水遮断弁9と、該冷却水遮断弁9の開閉動作を制御する制御手段10とを備えて、該制御手段10により、エンジン始動時に所定時間だけ冷却水遮断弁9を開き冷却水循環配管8に冷却水を循環させるものである。
【選択図】 図2
Description
先ず、図3に示すステップS1において、制御手段10は、上記各構成要素の所定の部位に設置された各種センサー、例えばエンジン始動センサー、大気温度センサー、ポンプ部内温度センサー、尿素水タンク内温度センサー、エンジン回転数検出センサー等の信号を読み込む。
さらに、ステップS11においては、冷却水遮断弁9を開く。そして、エンジン1から冷却水循環配管8に冷却水の一部を導き、図2に示す矢印E,F,G,H方向に冷却水を循環させる。
一方、ステップS12おいて、所定の時間が経過しておらず“NO”判定となった場合には、ステップS15に進む。
