Description
以下、この発明にかかる液体の残量検出装置を車両に搭載されたディーゼルエンジン(以下、「エンジン」という)に適用した第1実施形態について、図1〜図3を参照して説明する。
停止時残量PR=尿素供給量の積算値S+尿素供給の開始後にレベルセンサ250によって検出されるセンサ残量値SR …(1)
ちなみに、機関運転中は排気熱等により尿素水の凍結が起きにくい。従って、機関停止直後は、機関始動直後に比べて尿素水が凍結している可能性は低く、センサ残量値SRの信頼性も高い。そのため、尿素水供給を開始する前の尿素残量、換言すれば積算噴射量QESを減算する尿素残量として機関停止直後のセンサ残量値SR、つまり上記停止時残量PRを利用することにより、推定残量ARの信頼性が高まるようになる。
(第2実施形態)
次に、この発明にかかる液体の残量検出装置を具体化した第2実施形態について、図4及び図5を参照して説明する。
