ABSTRACT:
A filter block for filtering particles contained in the exhaust gas of an internal combustion engine includes a plurality of channels for the circulation of the gas, a channel defined by a wall provided with a filtering zone and which opens out towards the outside via an opening, a group of channels including at least two channels with different respective F/P ratios between surface F of the filtering zone and surface P of the wall. One channel of the group of channels includes an opening whose surface O is larger than the surface F of the filtering zone of the channel.
