Abstract

An internal combustion engine includes apparatus for reducing pollutants contained in exhaust gases omitted from the engine, the apparatus comprising a casing (1) defining a chamber containing a catalyst (3), the catalyst including a substrate made from filamentary metallic material in knitted, woven or crushed form, a first layer of a refractory metal oxide applied to the substrate and a second layer of a catalytic material applied to the first layer, the chamber having an inlet in communication with the exhaust ports (7, 8, 9, 10) of the engine via which exhaust gas emitted from the engine is lead into the chamber and passed through the catalyst prior to passage through an exhaust system (11) to atmosphere. <IMAGE> [GB2054402A]
