Oxidation catalyst for motor obtained by determining first length of catalyst support covered with catalyst material and quantity of material to cover support, determining second length of support and distributing material on second length

摘要

Oxidation catalyst (4) obtained by: determination of at least one first length of a catalyst support (4) covered with a oxidation catalyst material (43) and a quantity of the material to cover the support, where the first length and the quantity of catalyst in an outlet of catalyst at a level of polluting gas emission are lower to a predefined threshold; determination of a second length of the catalyst support, where the second length of catalyst is greater than at least 20 millimeters to the first length; and distribution of the quantity of material on the whole second length, is claimed. An independent claim is included for a method of manufacturing a motor vehicle, comprising preparing a catalyst; and assembling the catalyst on the exhaust line (2) of the predetermined internal combustion engine (1).
