Przedstawiony w publikacji sposób badania warstw katalitycznych, polega na tym, że bada się skuteczność katalizatorów przy różnych temperaturach spalin. Katalizator zainstalowany jest w stalowej rurze, którą umieszcza się w piecu i mierzy się temperaturę przed i za katalizatorem. Pomiar stężeń NO, N2O, CO, CO2 i HC wykonuje się w analizatorze z wykorzystaniem zjawiska pochłaniania części promieniowania podczerwonego emitowanego przez źródło promieniowania o widmie ciągłym, dodatkowo zawartość O2 mierzy się metodą elektrochemiczną. Ponadto tuż za kolektorem wylotowym do spalin dodaje się propan w charakterze reduktora, w stałej dawce około 1000 ppm. Dawkę gazu odmierza się przy pomocy rotametru.In the publication of Kruczyński S., Kwiatkowski M., Zieliński Y .: "Comparative analysis of NOx reduction with hydrocarbons on oxide catalysts in diesel exhaust gas, Journal of KONES Internal Combustion Engines 2002 No. 3-4, a method of selective catalytic reduction is described. NOx, with the aid of hydrocarbons in the exhaust of a compression ignition engine, with evaluation of the effectiveness of several catalysts. The method of testing catalytic layers presented in the publication consists in testing the effectiveness of catalysts at different exhaust gas temperatures. The catalyst is installed in a steel tube which is placed in the furnace and the temperature is measured upstream and downstream of the catalyst. Measurement of NO, N2O, CO, CO2 and HC concentrations is performed in the analyzer using the phenomenon of absorption of a part of the infrared radiation emitted by a radiation source with a continuous spectrum, additionally the O2 content is measured by an electrochemical method. In addition, propane is added to the exhaust gas as a reducing agent just downstream of the exhaust manifold, in a fixed dose of about 1000 ppm. The dose of gas is measured using a rotameter.
