Device for treating exhaust gases

Abstract

A device ( 1 ) for exhaust treatment of an internal combustion engine, in particular a diesel internal combustion engine, having a particle filter ( 4 ), is proposed that is to be realized with less expense than conventional systems and ensures reliable particle filter regeneration. This is obtained according to the invention by the fact that the device ( 1 ) comprises a catalytic burner ( 3 ), whereby the burner ( 3 ) is located between the internal combustion engine and the particle filter ( 4 ).

What is claimed is:  
     
         1 . A device ( 1 ) for exhaust treatment of an internal combustion engine, in particular a diesel internal combustion engine, having a particle filter ( 4 ), wherein the device comprises a catalytic burner ( 3 ), whereby the burner ( 3 ) is located between the internal combustion engine and the particle filter ( 4 ).  
     
     
         2 . The device ( 1 ) according to  claim 1 , 
 wherein a fuel metering device ( 5 ) is located between the internal combustion engine and the burner ( 3 ).    
     
     
         3 . The device ( 1 ) according to one of the aforementioned claims, wherein the fuel metering device ( 5 ) comprises a fuel dispersal unit.  
     
     
         4 . The device ( 1 ) according to one of the aforementioned claims, wherein an open-loop control of the fuel metering device ( 5 ) is provided.  
     
     
         5 . The device ( 1 ) according to one of the aforementioned claims, wherein the device ( 1 ) comprises a nitrogen oxide oxidation unit ( 7 ).  
     
     
         6 . The device ( 1 ) according to one of the aforementioned claims, wherein the device ( 1 ) comprises a coated particle filter ( 8 ).  
     
     
         7 . The device ( 1 ) according to one of the aforementioned claims, wherein the device ( 1 ) comprises a heating device ( 6 ).  
     
     
         8 . A vehicle, 
 wherein a device ( 1 ) according to one of the aforementioned claims is provided.    
     
     
         9 . A method for exhaust treatment of an internal combustion engine, in particular a diesel internal combustion engine, having a particle filter ( 4 ), wherein a device ( 1 ) according to one of the aforementioned claims is used.
