Title (EN) EXHAUST GAS PURIFICATION DEVICE FOR AN INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF D'ÉPURATION DES GAZ D'ÉCHAPPEMENT D'UN MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関の排気浄化装置
Abstract:
(EN) Provided is an exhaust gas purification device for an internal combustion engine, in which an additive supplied to said exhaust gas purification device for an internal combustion engine is uniformly dispersed in the exhaust gas. An upstream-side exhaust gas purification device and a downstream-side exhaust gas purification device are connected by an exhaust pipe having a smaller cross-sectional area than that of the upstream-side exhaust gas purification device and the downstream-side exhaust gas purification device, and a connecting passage for connecting an exhaust outlet for a catalyst in the upstream-side exhaust gas purification device and the exhaust pipe is provided. The connecting passage is formed in such a way that the axial centre line of the upstream-side exhaust gas purification device in the direction of flow of the exhaust gas and the axial centre line of the exhaust pipe in the direction of flow of the exhaust gas are not aligned, and injection means for injecting the additive into an exhaust passage are disposed in the connecting passage. The additive is injected in such a way as to reach the opposite wall surface of the connecting passage.
(FR) L'invention permet de disperser uniformément dans des gaz d'échappement un additif alimenté dans un dispositif d'épuration des gaz d'échappement d'un moteur à combustion interne. Un dispositif d'épuration des gaz d'échappement du côté amont et un dispositif d'épuration des gaz d'échappement du côté aval sont raccordés, à l'aide d'un conduit de gaz d'échappement dont la surface de section transversale est moindre que la surface de section transversale du dispositif d'épuration des gaz d'échappement du côté amont et du dispositif d'épuration des gaz d'échappement du côté aval. Le dispositif met en œuvre une partie de voie de raccord qui raccorde la sortie d'échappement d'un catalyseur du dispositif d'épuration de gaz d'échappement du côté amont avec le conduit de gaz d'échappement. La partie de voie de raccord est formée de telle sorte que la ligne d'axe centrale dans le sens d'écoulement des gaz d'échappement du dispositif d'épuration de gaz d'échappement du côté amont ne corresponde pas à la ligne axiale centrale dans le sens d'écoulement des gaz d'échappement du conduit de gaz d'échappement. Un moyen d'injection, injectant un additif dans la voie de gaz d'échappement, est disposé sur la partie de voie de raccord, et l'injecte de telle sorte que l'additif atteigne la surface d'une paroi faisant face à la partie de voie de raccord.
(JA)   内燃機関の排気浄化装置に供給する添加剤を、排気中に均一に分散させる。上流側排気浄化装置と下流側排気浄化装置との間を、上流側排気浄化装置と下流側排気浄化装置の断面積よりも断面積が小さい排気管で接続し、上流側排気浄化装置の触媒の排気出口と排気管とを接続する接続通路部を備え、接続通路部を、上流側排気浄化装置の排気流れ方向中心軸線と、排気管の排気流れ方向中心軸線とが、一致しないように形成し、添加剤を排気通路内に噴射する噴射手段を、接続通路部に配置し、添加剤が、接続通路部の、対向する壁面に到達するように噴射する。
