Abstract (en)
[origin: WO9901648A1] 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 catalyst volume (7) and the hydraulic diameter of its flow channels (9) to the engine capacity (3) of the combustion engine (1) enables the exhaust gas back pressure to be reduced due to a high contaminant conversion rate and a mitigated occlusion trend, with no engine capacity loss.
