Abstract (en)
[origin: EP0340784A1] The device (1) comprises a hollow casing (2) provided with an inlet (3) for exhaust gases to be purified and an outlet (4) for the purified exhaust gases, and purifier means (5) interposed between the said inlet (3) and outlet (4) and substantially constituted by mineral fibres (6) activated by a noble metal catalyst deposited on them. The device (1) further includes support means (15) for the mineral fibres (6) essentially constituted by a woven filiform material engaged on the fibres (6) in such a way as to define, between the said inlet (3) and outlet (4), a substantial alternation of layers of filiform material (15) and mineral fibres (6).
