Title:
内燃機関の排気浄化装置
Document Type and Number:
Japanese Patent JP5835330
Kind Code:
B2
Abstract:
The present invention resides in an exhaust gas purification apparatus for an internal combustion engine, comprising an exhaust gas purification catalyst which is arranged in an exhaust gas passage of the internal combustion engine for a reducing agent added from a reducing agent addition valve, the reducing agent addition valve which adds the reducing agent to an exhaust gas allowed to flow upstream from the exhaust gas purification catalyst, and a dispersion member which disperses the reducing agent added from the reducing agent addition valve, wherein a task or object thereof is to form fine particles of the reducing agent and improve the dispersibility while suppressing the increase in the exhaust resistance caused by the dispersion member to be small. In order to solve the task or achieve the object, in the present invention, the dispersion member is arranged only on a flight route of a coarse reducing agent which is included in the reducing agent added from the reducing agent addition valve and which has relatively large particle diameters.
