Title (EN) ENGINE SYSTEM WITH REFORMING DEVICE
(FR) SYSTÈME MOTEUR AVEC DISPOSITIF DE REFORMAGE
(JA) 改質器付エンジンシステム
Abstract:
(EN) Disclosed is an engine system wherein a reforming device for reforming a fuel is mounted in an exhaust pipe, characterized in that a control valve which controls the flow rate of exhaust air is provided downstream from the outlet of the reforming device in the exhaust pipe.  In the engine system with the reforming device, the control valve is closed during an exhaust process so that a part of the exhaust gas can be confined in a space between the reforming device and an engine chamber.  Thus, the reforming efficiency of the reforming device can be enhanced.
(FR) L'invention porte sur un système moteur dans lequel un dispositif de reformage destiné à reformer un carburant est monté dans un tuyau d'échappement, caractérisé en ce qu'une soupape de commande commandant le débit de l'air d'échappement est disposée en aval de la sortie du dispositif de reformage dans le tuyau d'échappement. Dans le système moteur avec dispositif de reformage, on ferme la soupape de commande durant un processus d'échappement de telle sorte qu'une partie de l'air d'échappement peut être confinée dans un espace entre le dispositif de reformage et une chambre du moteur. On peut améliorer ainsi le rendement de reformage du dispositif de reformage.
(JA)  排気管に燃料を改質する改質器を搭載したエンジンシステムにおいて、前記排気管の改質器出口より下流側に排気流量を調整する調整バルブを有することを特徴とする改質器付エンジンシステムである。この改質器付エンジンシステムにおいて、排気行程途中において調整バルブを閉めることで、排ガスの一部を改質器とエンジン室の間に閉じ込めることができるため、改質器の改質効率を高めることができる。
