Abstract
Description
λ<1(例えば0.9)は、「空気の不足」、すなわちリッチ混合気を意味し、
λ>1(例えば1.1)は、「空気の過剰」、すなわちリーン混合気を意味する。
− エンジンおよびシステムの調節装置を制御するユニット(ECU)、
− 吸気を絞る装置(11)、
− 空燃比を検出する第1センサ(12)、
− 窒素酸化物吸蔵触媒コンバータ(5)、
− 粒子フィルタ(6)と、
− 空燃比を検出する第2センサ(13)、
− 低圧EGR弁(9)を備える低圧ERGライン(14)、
− 任意選択的に、排ガスの排出を低減する装置(10)。
・窒素酸化物吸蔵触媒コンバータの脱硫中のH2S遮断触媒コンバータにおけるH2Sの吸収、
・例えば、エンジンの冷間始動中、または窒素酸化物吸蔵触媒コンバータあるいは粒子フィルタの再生中の炭化水素吸蔵材または酸化触媒コンバータにおける、炭化水素の吸収、
・効率的な排ガス浄化に対して窒素酸化物吸蔵触媒コンバータ(5)のNOx吸蔵作用がもはや十分でない、特に排ガス温度が上昇したエンジン動作点におけるNOx転化のさらなる改善を達成するための、例えばSCR触媒コンバータまたは窒素酸化物吸蔵触媒コンバータにおける窒素酸化物の吸収、
・窒素酸化物吸蔵触媒コンバータの再生中に形成されるアンモニアを取り込むための、例えばSCR触媒コンバータにおけるアンモニアの吸収。
・再生中のより低い燃料消費
・再生が可能であるさらなる運転状態。
・再生中の発熱の発生の低減、および結果としての再生後の窒素酸化物吸蔵触媒コンバータの改善された吸蔵挙動
・再生の開始時のNOx脱離ピークの低減、それは、脱離したNOxが、低圧EGRシステムを介して窒素酸化物吸蔵触媒コンバータを横切って複数回導かれ、その後、リッチ状態に還元されるためである。
・N2Oがリッチ運転条件下で窒素酸化物吸蔵触媒コンバータを横切って複数回導かれる結果としての、再生中のN2Oの低減。
・NOxが窒素酸化物吸蔵触媒コンバータを横切って複数回還元されてNH3を形成する可能性の結果としての高いNH3収率。
・還元剤のより効率的な利用の結果としての再生中の炭化水素およびCO排出量の低減。
2.オーバーラン運転が存在する時、DPF再生中に脱硫を行うことができる。
3.脱硫は、エンジンのさらなる運転状態で発生することができる。
4.低圧EGRにおける排ガスをリッチ状態に設定するためにわずかな量の燃料のみが必要であるため、脱硫中に燃料消費が大幅に低減すること。
5.リッチ段階が長期化し、したがって、触媒コンバータの経年化に決定的なリッチ/リーンの交代が低減する結果として、NOx吸蔵触媒コンバータの熱劣化が低減すること。
6.脱硫中のオイル希釈効果が低減すること。
7.例えば運転の快適さ、排出物およびオイル希釈の理由で通常の走行動作では困難なしには実施可能でない、リッチ条件下でのより長い期間の走行が可能であることによる、より効率的な脱硫。
