Abstract:
The invention proposes a method for the purification of exhaust gases which are generated by a diesel engine with a charging turbine, and a special device for carrying out said method. The device comprises, in the flow direction of the exhaust gas, a dosing device for a reducing agent from a reducing agent reservoir ( 2 ), an SCR catalytic converter ( 3 ), an oxidation catalytic converter ( 4 ) and a diesel particle filter ( 5 ). The system is particularly suitable for the purification of the exhaust gases of diesel vehicles in which engines with a turbocharger (charging turbine ( 1 )) and an exhaust-gas recirculation device are used, which engines generate exhaust gases which, in addition to carbon monoxide, hydrocarbons and particles, have nitrogen oxides with an NO 2 /NO X  ratio of between 0.3 and 0.7.

Claim (Index 1):
A method for the purification of exhaust gases which are generated by a diesel engine with a charging turbine and which, in addition to carbon monoxide, hydrocarbons and particles, contain nitrogen oxides with an NO 2 /NO x  ratio of between 0.3 and 0.7, with the exhaust gas being conducted via an SCR catalytic converter for the reduction of the nitrogen oxides to form nitrogen, via an oxidation catalytic converter for the oxidation of carbon monoxide and hydrocarbons to form CO 2 , and through a diesel particle filter for the removal of particles,\n wherein urea solution, or the solution of some other water-soluble compound which releases ammonia, is used as a reducing agent for the SCR reaction, which reducing agent is dosed into the exhaust section upstream of the charging turbine.
