Title (EN) EXHAUST GAS PURIFICATION SYSTEM
(FR) SYSTÈME DE PURIFICATION DE GAZ D'ÉCHAPPEMENT
(JA) 排ガス浄化システム
Abstract:
(EN) The purpose of the present invention is to provide an exhaust gas purification system which exhibits high exhaust gas purification performance. The present invention is an exhaust gas purification system which is provided with: an exhaust gas purification device which is provided with a carrier that contains aluminum oxide and a catalyst that is provided on the carrier and contains gallium, and which is connected to an internal combustion engine; and a system which is connected to the exhaust gas purification device and enhances the oxygen concentration. This exhaust gas purification system is characterized in that the system for enhancing the oxygen concentration enhances the oxygen concentration to a value that is higher than the oxygen concentration of the post-combustion gas of the internal combustion engine.
(FR) La présente invention vise à fournir un système de purification de gaz d'échappement avec une meilleure performance de purification de gaz d'échappement. La présente invention concerne un système de purification de gaz d'échappement qui est pourvu: d'un dispositif de purification de gaz d'échappement qui est pourvu d'un support contenant de l'oxyde d'aluminium et d'un catalyseur disposé sur le support et contenant du gallium, et qui est relié à un moteur à combustion interne; et un système qui est relié au dispositif de purification de gaz d'échappement et qui améliore la concentration en oxygène. Ce système de purification de gaz d'échappement est caractérisé en ce que le système d'amélioration de la concentration en oxygène améliore cette concentration à une valeur qui est supérieure à celle du gaz de post-combustion du moteur à combustion interne.
(JA) 本発明の目的は、高い排ガス浄化性能を示す排ガス浄化システムを提供することである。本発明は、酸化アルミニウムを含む担体と、前記担体に設けられガリウムを含む触媒を備え、内燃機関と繋がる排ガス浄化装置と、前記排ガス浄化装置と接続され、酸素濃度を高めるシステムと、を有する排ガス浄化システムにおいて、前記酸素濃度を高めるシステムは、前記内燃機関の燃焼後ガスの酸素濃度よりも高い酸素濃度にすることを特徴としてなるものである。
