Particulate Filter for an Internal Combustion Engine

Abstract

The invention relates to a particulate filter comprising a monolithic filter body ( 10 ) with inflow channels ( 12 ) and outflow channels ( 13 ) that run at an angle to said inflow channels. Each inflow channel is separated from the outflow channels by at least one filter wall. The inflow channels ( 12 ) run in a linear manner into a chamber ( 17 ), in which the ash collects. The purified gases exit the particulate filter via an outlet ( 21 ).

1 . A particulate for an internal combustion engine, comprising a monolithic porous filter body having inflow channels and outflow channels, each inflow channel crossing at lest one outflow channel from which it is separated by a filtering wall,
 wherein   the inflow channels open into a setting chamber which is an ash chamber for depositing ash.   
   
   
       2 . The particulate filter of  claim 1 , wherein each inflow channel crosses a plurality of outflow channels and each outflow channel crosses a plurality of inflow channels. 
   
   
       3 . The particulate filter of  claim 1 , wherein a plurality of inflow channels are arranged adjoining in a first plane and a plurality of outflow channels are arranged adjoining in a second plane parallel to the first plane. 
   
   
       4 . The particulate filter of  claim 1 , wherein the inflow channels are tubes that pass through chambers without their walls contacting each other, said chambers forming the outflow channels. 
   
   
       5 . The particulate filter of  claim 1 , wherein the outflow channels are tubes that pass through chambers without their walls contacting each other, said chambers forming the inflow channels. 
   
   
       6 . The particulate filter of  claim 1 , wherein the settling chamber has a flap for removing the ash therefrom.
