発明の名称
(EN) CONDENSED WATER TREATING APPARATUS FOR INTERNAL COMBUSTION ENGINE
(FR) APPAREIL DE TRAITEMENT D'EAU CONDENSÉE POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の凝縮水処理装置
要約
(EN) A condensed water treating apparatus is configured such that the lower the pH of condensed water generated by the exhaust system of an internal combustion engine, the more the amount of condensed water supplied to the intake system of the internal combustion engine is reduced, and such that the lower the engine rotational speed of the internal combustion engine given a constant pH of condensed water, the more the amount of supplied condensed water is reduced.
(FR) L'invention concerne un appareil de traitement d'eau condensée qui est configuré de telle sorte que plus le pH de l'eau condensée, générée par le système d'échappement d'un moteur à combustion interne, est bas, plus la quantité d'eau condensée introduite dans le système d'admission du moteur à combustion interne est réduite, et de telle sorte que plus la vitesse de rotation du moteur du moteur à combustion interne qui a un pH constant d'eau condensée est faible, plus la quantité d'eau condensée introduite est réduite.
(JA)  凝縮水処理装置は、内燃機関の排気系で生成された凝縮水のpHが小さいほど内燃機関の吸気系への凝縮水の供給量を低下させ、かつ凝縮水のpHが同一の場合は内燃機関のエンジン回転速度が低いほど凝縮水の供給量を低下させる。
