Oxidation catalytic converter design - GF49.10-P-3000-01GB
Illustration of oxidation catalytic converter close to engine
The catalytic converter consists of a stainless steel housing (111/1), an expanding mat (120/3) and the substrate (ceramic monolith) with the actual catalytic coating.
Ceramic monoliths are ceramic bodies through which pass several thousand small passages. The ceramic consists of a high temperature-resistant magnesium aluminum silicate.
The monolith, which is extremely sensitive to stresses, is mounted in the stainless steel housing, embedded in a flexible expanding mat.
The active catalytic layer applied to the substrate consists of platinum. Platinum promotes the oxidation of hydrocarbons (HC) and carbon monoxide (CO).
In addition, a part of the oxides of nitrogen (NO X ) is reduced.
The content of rare metals contained in a catalytic converter is approx. 4.5 to 5.0 grams, depending on size and design.
