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 3):
The method as claimed in  claim 1 ,\n wherein the diesel particle filter is actively regenerated in the event of a critical exhaust-gas counterpressure value being exceeded, with the temperatures required for burning off the soot which has been deposited on the filter being generated by means of a post-injection of fuel into the exhaust section and a catalytic combustion of the fuel.
