Abstract (en)

[origin: WO9901647A1] In order to eliminate contaminants in exhaust gas from an air excess-driven combustion engine (1) with a given engine capacity (3), an alveolate catalyst (7) is disclosed as well as a method consisting in feeding said exhaust gas via an exhaust pipe (2) into the catalyst (7). Adapting the surface of approach (11) to the engine capacity (3) enables, with a hydraulic flow channel (9) diameter of 2 to 4 mm and a front area aperture at the catalyst inlet (7) of 45 to 95 %, a high contaminant conversion rate to be obtained with no engine capacity reduction.
