This article presents test results obtained for nitrogen oxides emission reduction by the method of selective catalytic reduction in a diesel engine. A special steady-state test cycle was prepared in order to identify the most critical operating points of the SCR system. Areas of low system performance and the reasons for solid fractions formation and deposition were also investigated. The research examined the phenomenon of the occurrence of ammonia slip emissions into the environment.

W artykule zawarto wyniki badań systemu zmniejszania emisji tlenków azotu metodą selektywnej redukcji katalitycznej SCR. Opracowano test badawczy, w którym wskazano krytyczne stany pracy systemu. Zidentyfikowano obszary małej skuteczności redukcji oraz przyczyny odkładania się stałych depozytów. Zbadano także przyczyny pojawiania się emisji amoniaku do otoczenia.
