Abstract (en)
[origin: EP2716884A1] An object is to suppress any deviation of an addition agent to be supplied into an exhaust gas discharged from an internal combustion engine so that the addition agent is dispersed more uniformly. For this purpose, there is provided an exhaust gas purification apparatus for an internal combustion engine, comprising an exhaust gas purification catalyst which is provided for an exhaust gas passage of the internal combustion engine; a supply unit which supplies an addition agent to the exhaust gas purification catalyst; and a dispersing unit (5) which is provided between the exhaust gas purification catalyst and the supply unit and which disperses the addition agent; wherein the dispersing unit (5) includes a first gas flow forming portion (54) and a second gas flow forming portion (55); and the first gas flow forming portion (54) and the second gas flow forming portion (55) are formed so that a first gas flow having passed through the first gas flow forming portion (54) and a second gas flow having passed through the second gas flow forming portion (54) interfere with each other.
