The paper presents a proposition of simulation studies of nitrogen oxide catalytic reduction. The method enables estimating the influence of catalytic reactors on ecological properties of engines in static bench tests (e.g., ECE R49, United Nations Economic Commission for Europe [UN/ECE], 2000; Standard No. ISO 8178-4:1996, International Organization for Standardization [ISO], 1996; Merkisz (1998). An algorithm of simulation studies is shown. A model catalytic reactor for selective catalytic reduction is described. Silver aluminate deposited on steel substrate covered with aluminium phosphate is used as a catalyst. Propene is used as a reductant. The results of reactor studies in a chemical lab are presented. A simulation of the influence of catalytic reactor properties on ecological properties of an engine was done. Unitary emission conversion coefficients of nitrogen oxide in a static test ECE R49 were determined.
