Análise de desempenho e emissão de poluentes em motor de ignição por compressão utilizando combustível diesel com adição de etanol

Abstract

A compression ignition engine simulation was performed using diesel fuel mixed with ethanol. The engine considered for the simulation was the electronic engine OM-924 LA from the manufacturer Mercedes-Benz, with 4 cylinders, with 208 horsepower. The russian software called Diesel-RK was used to perform the modeling and validation of the engine, as well as all the mixing simulations because this software is able to predict the performance as well as the formation and emission of different pollutants harmful to the environment. The analysis of the results show that engine performance and consumption slightly increases with the addition of ethanol, as well as thermal efficiency. As for the emissions of gases analyzed, there was a reduction in the emission of NOx and particulate matter.
