Abstract:
1. An exhaust-gas system, comprising: an exhaust-gas pipe for guiding an exhaust-gas flow; an injection nozzle mounted to said exhaust-gas pipe for injecting a reducing agent into the exhaust-gas flow, said injection nozzle being configured to inject the reducing agent into the exhaust gas flow in form of an atomizing cone; an exhaust-gas pipe branching device downstream of said injection nozzle, dividing said exhaust-gas pipe into at least two exhaust-gas lines; a separate SCR catalytic converter disposed in each one of said exhaust-gas lines; a fluid divider disposed between said injection nozzle and said branching device, said fluid divider having a front face facing upstream into the exhaust-gas flow and intersecting a projection of said atomizing cone on a cross-sectional area of said exhaust gas pipe and the front face being oriented with respect to the cross-sectional area of the exhaust-gas pipe to divide the exhaust-gas flow and the reducing agent between said at least two exhaust-gas lines in a predefinable dividing ratio.
