Description
更に、この発明によれば、可変容量過給機のタービン入口面積を減少させ、排気が絞られるので、更なる温度の上昇が可能となる。
エンジン1は直列に4つの燃焼室2を配備し、各燃焼室2には直接燃料を噴射する燃料噴射弁3が設けられている。ここで燃料タンク4の燃料(軽油)は高圧燃料噴射ポンプ5で加圧されてコモンレール6(蓄圧室)に圧送され、コモンレール6から燃料噴射弁3を介し各気筒内に噴射される。ここでの燃料噴射弁3は後述のECU7から出力される燃料制御信号に応じてその燃料噴射量Qnと噴射時期Tnが制御される。
触媒コンバータ29はそのケーシング291内に長手方向に沿ってNOx還元触媒31と、ディーゼルパティキュレートフィルタ32とを順に収容する。
車両にはエンジン制御手段であるエンジンコントロールユニット(以後単にECU7と記す)が設けられている。
ここで、走行履歴算出手段A1は車両の走行距離あるいはエンジンの作動時間相当のカウント量tn(単位走行距離あるいはエンジンの単位作動時間毎に加算される値)をエンジンの作動時間中に積算して、積算値(ΣCount←ΣCount+tn)を順次求める。
スロットル制御手段A4は吸気スロットル弁41の開度θsを吸気絞り弁開度信号を受けた際に、吸気スロットル弁41を介し指令相当の開度に吸気スロットル弁41を切換え制御できる。
更に、ここではエンジン回転数Neとアクセル開度θa相当の通常吸気スロットル開度マップ(図4(c−1)に示す)map3nを用い、通常スロットル開度θs1(大側開度)を算出し、同開度に切換え保持する。
このようなステップs1〜ステップs3の通常運転指令Snの運転中において、排気ガスは触媒コンバータ29に流入する。
