In this article, the main reasons for the intensive development work being done on automotive emission control catalysts are discussed and the most important features of these technologies are described. Special attention is paid to the development of improved three-way catalysts for gasoline engines, that have to fulfil the more stringent future emission standards. Diesel fuelled vehicles and lean burn gasoline engines show completely different exhaust gas emission characteristics, which lead to dissimilar demands for the aftertreatment systems.
