Abstract

The invention relates to an exhaust gas purification system for decreasing the emissions of hydrocarbons during the cold start of internal combustion engines. The exhaust gas purification system contains a hydrocarbon adsorber and a downstream catalyst system which can be composed of a single three-way catalyst or of a combination of oxidation, reduction and/or three-way catalysts in one or more beds. The hydrocarbon emissions during the cold start phase can be significantly decreased by using oxidation catalysts or three-way catalysts which, in comparison with conventional catalysts, have at least twice the loading of platinum and/or palladium.
