EN Environmental emission of road transport is a key problem. Periodic environmental test are designed to ensure minimum emission. Periodic checks are based on measurements. In this emission measurements fuel type plays an important role. The Brettschneider equation is a method used to compare the idealized and actual air fuel ratio. Brettschneider established a method to calculate ratio of oxygen to fuel by comparing the ratio of oxygen molecules to carbon and hydrogen molecules in the exhaust. In this article, authors have investigated blended ethanol effect on idealized and actual air fuel ratio based on Brettschneider equation. The main result of the article that blended ethanol has insignificant effect on air-fuel ratio. The article presents inter alia difference in stoichiometric air fuel ratios in case of different fuels, changes in λ due to blending ethanol and comparison of influence of emissions of different types of transport. In the article authors focus particularly on periodic checks and gasoline driven cars. The main research question was if ethanol blends have effect on idealized and actual air fuel ratio based on Brettschneider equation
