Abstract
NOX emissions are a health hazard, and are increasingly regulated in cars. NOx also contributes to the formation of acid rain and the eutrophication of ecosystems. Nitrogen oxides are a family of molecules including nitrogen monoxide (NO) and nitrogen dioxide (NO2). These gases are formed in the engine during high-temperature fuel combustion, and play a role in the formation of fine particles in ambient air. In this article, the aim is to determine the nitrogen content of gasoline samples taken at four gasoline stations of the most representative groups in terms of distribution of light petroleum products in order to assess the environmental impact due to greenhouse gas emissions resulting from the use of gasoline by vehicles and to reduce the nitrogen content in the form of nitrogen oxides NOx. After an introduction, we presented the material and the method used, followed by the results of our analyses and a discussion of the results obtained before concluding.
