In the article there was reviewed the principle of operation of the SCR type catalitic reactors and explained the reason, why ammonia appears in the exhaust gas. The principles of analyzers to measure the concentrations of ammonia in the exhaust gases was reviewed. There were examined changes in EU regulations on the emissions of vehicles engines in comparison to UNECE Regulation No. 49, series 05 of amendments.

W artykule przedstawiono zasadę działania reaktorów katalitycznych typu SCR oraz wyjaśniono przyczynę, dla której w spalinach pojawia się amoniak. Dokonano przeglądu zasady działania analizatorów do pomiarów stężeń amoniaku w spalinach. Przeanalizowane zostały zmiany wprowadzone w rozporządzeniach UE dotyczących emisji zanieczyszczeń z układów wylotowych silników pojazdów w porównaniu z Regulaminem EKG ONZ nr 49, seria 05 poprawek.
