Concept of Catalytic Exhaust Emission Control for Europe

The experience which has been gained in more than ten years with vehicles for the U.S.A. and Japan forms the basis of the catalytic converter systems for application in Europe.

We are talking about the improvement of the mechanical and chemical endurance of catalytic converters and oxygen sensors. Special attention is paid to various substrate materials (e.g. steel) and coatings concerning their properties with regard to high-temperature stability and power loss. Moreover we are dealing with the increased application of electronics in the engine.

The paper mainly refers to the Mercedes-Benz 190 E 2.3-16. This vehicle is used as an example to show the development of an emission concept for European requirements.
