The inventive filter unit for filtering particles contained in exhaust gas of an internal combusting engine comprises sets of imbricated input channels (10, 11) and adjacent output channels (12, 13) which are fluidly communicating by means of the lateral walls thereof. Said lateral walls are cross-sectionally provided with a corrugation which is determined in such a way that the total volume of the input channels (10, 11) is increased with respect to that of the output channels (12, 13), whereby the total volume (Ve) of the input channels (10, 11) being greater than that (Vs) of the output channels (12, 13).
Bloc filtrant pour la filtration des particules contenues dans les gaz d'échappement d'un moteur à combustion interne, comprenant des ensembles imbriqués de canaux d'entrée (10, 11) et de canaux de sortie 12, 13) adjacents, les canaux d'entrée (10, 11) et de sortie (12, 13) étant en communication de fluide par leurs parois latérales, les parois latérales présentant, en coupe transversale, une ondulation déterminée de manière à accroître le volume global des canaux d'entrée (10, 11) aux dépens de celui des canaux de sortie (12, 13), et le volume global (Ve) des canaux d'entrée (10, 11) étant supérieur à celui (Vs) des canaux de sortie (12, 13).
