The present invention is directed to a method for purifying exhaust gas generated by a diesel engine having a supercharged turbine and a special apparatus for carrying out the method. The apparatus includes a metering device for reducing agent solution from the reducing agent reservoir (2), an SCR catalytic converter (3), an oxidation catalytic converter (4) and a diesel particulate filter (5) in the flow direction of the exhaust gas. Become. The system is particularly suitable for exhaust gas purification of diesel vehicles in which an engine having a turbocharger (supercharged turbine (1)) and an exhaust gas recirculation device is used, the engine comprising carbon monoxide, hydrocarbons and particulates In addition, an exhaust gas containing nitrogen oxides having a NO 2 / NO x ratio of 0.3 to 0.7 is generated. |
