This paper examines emissions of reactive nitrogen compounds in the exhaust gas flux of vehicles featuring spark ignition (SI) engines. A range of technical, legal and environmental aspects are considered. A discussion of the fundamentals of the phenomenon of emission of these compounds is presented, together with a brief summary of the negative environmental impacts of these gases. Selected data obtained during chassis dynamometer testing at BOSMAL are presented, together with certain important observations presented in the technical literature. The reader is directed to recent publications of note for further information on emissions to the less well known reactive nitrogen compounds, namely NH₃ and N₂O. The orders of magnitude of the various reactive nitrogen compounds found in the exhaust gas emitted from SI engines are briefly considered and commented upon. Data are presented on the impact of different fuel types used in SI engines and the reader is directed to various publications on that subject. Finally, important research directions (both current and future) are identified.

W artykule zawarto analizę problematyki emisji reaktywnych związków azotu w spalinach silników samochodowych o zapłonie iskrowym (ZI). Omówiono przyczyny powstawania tych związków w spalinach silnikowych, ich emisję oraz negatywny wpływ na środowisko. Przedstawiono wybrane wyniki badań emisji reaktywnych związków azotu w odniesieniu do pojazdów zasilanych paliwami konwencjonalnymi i alternatywnymi, uzyskane w testach emisji na hamowni podwoziowej. Prezentowane wyniki porównano do wyników z tego zakresu opisanych w literaturze. Przedstawiono obecne i przyszłe kierunki badań emisji związków azotu w spalinach silnikowych.
