Title (EN) CONDENSED WATER PROCESSING DEVICE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE TRAITEMENT D'EAU CONDENSÉE POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の凝縮水処理装置
Abstract: front page image
(EN)This condensed water processing device determines (S2) whether or not the pH of condensed water stored in a condensed water tank is less than a threshold (t). When the pH of the condensed water is less than the threshold (t), the amount of supply of urea water supplied upstream of an NOx catalyst is increased (S7) beyond that during normal control (S4) carried out when the pH of the condensed water is at least the threshold (t).
(FR)Ce dispositif de traitement d'eau condensée détermine (S2) si le pH de l'eau condensée stockée dans un réservoir d'eau condensée est inférieur ou non à un seuil (t). Lorsque le pH de l'eau condensée est inférieur au seuil (t), la quantité d'alimentation en eau d'urée apportée en amont d'un catalyseur de NOx est augmentée (S7) au-delà de celle qu'on a durant une commande normale (S4) réalisée lorsque le pH de l'eau condensée est au moins égal au seuil (t).
(JA) 凝縮水処理装置は、凝縮水タンクに貯留された凝縮水のpHが閾値tよりも小さいか否かを判定する(S2)。凝縮水のpHが閾値tよりも小さい場合は、NOx触媒の上流に供給する尿素水の供給量を、凝縮水のpHが閾値t以上の場合に実施する通常制御時(S4)よりも増加させる(S7)。
