<p>Purification of the exhaust gases of diesel engines, particularly for motor vehicles, by a device with a plurality of macrocells in a substrate of porous ceramic. The macrocells preferably are small channels (10,11) which are mutually parallel, in a monolithic ceramic body (8). Some of the channels (10,11) are open upstram and others are open downstream. The channels (11) which are open upstream are filled with an insert body (13) of compacted metal threads, which support catalytic material. Such a device, connected into the exhaust line of a diesel engine, forms a carbon filter, which is distinguished by high filter action with a relatively lower exhaust-gas counterpressure and a relatively low carbon combustion temperature.</p> |
