The Brazilian energy matrix, in the transportation sector, has 17% of its energy from biofuels such as ethanol and biodiesel, where 14% corresponds to ethanol (anhydrous 6% and hydrous 8%) (MME - 2014).There are many investments in agricultural sector in the sugar cane planting and in the industrial ethanol production phase. But after the 80s, when the automakers stopped manufacturing dedicated ethanol engine vehicles, there was a stagnation in engine ethanol improvement studies. Despite the advent of flex-fuel engines, capable of operating with ethanol, there are more studies for gasoline spark ignition engines, or the blend of the two fuels.The objective of this project is to contribute to the technological progress of ethanol spark ignition engines, by developing simulation models of formation of gross emissions of NOx, CO, UHC, to be used in future performance simulation models, besides used in modified and optimized ethanol engine emission models.A phenomenological Thermodynamic model will be used in a typical ethanol engine, which consists in an analysis of the first and second Laws of Thermodynamics, further including the chemical balance of the main species and models of formation of pollutants. This project is intended to develop pollutants training simulation tools of ethanol engines, which will be later be used in a simulation model of an advanced ethanol engine, that is present in modern technologies.
