GF49.10-P-3006GZ Component Description For The Oxidation Catalytic Convertor







Location
The oxidation catalytic converter is near-engine mounted downstream of the turbocharger.

Task
Reducing the pollutant components of carbon monoxide (CO), hydrocarbon (HC), oxides of nitrogen (NOx)











The exhaust flow consists of a number substances including:
- CO
- HC
- NOX

Function
The ceramic monolith is a ceramic body through which many thousands are small passages are drawn. The ceramic consists of a high temperature-resistant magnesium-aluminium silicate.

The monolith which is extremely sensitive to voltages is embedded in an elastic expanded matting and mounted in a stainless steel housing.

Coating
The carrier layer applied to the ceramic monolith with the operative catalytic layer consists of platinum and accelerates oxidation of HCs and CO.

The HC and CO act to reduce the NOx portion. This is made possible by the special catalytic converter design.

The content of rare metals contained in an oxidation catalytic converter is approx. 5 grams, depending on size and design.
