Abstract - In this paper a new conception of layers of the catalytic converter has been presented that allows to increase the contact area of reagents originating in exhaust gas and to rise the catalytic deposit temperature to the value which makes possible to extend the converter operation range in order to reduce the emission of nitrogen oxides and particular matter. Moreover, the results of examination of the catalytic converter tested at the engine test according to test bed for different catalytic blocks has been presented. Ten different combinations of the catalytic blocks have been subject to the examination and each combination included the basic composition in a form of aluminum oxide and platinum and some modified deposits consisting of different contents of palladium, ruthenium and nano-structure of cerium-zirconium oxides / ruthenium in a form of spheres.
