“…Exhaust gas recirculation (EGR), which returns a portion of the engine exhaust gas to the combustion chamber via the intake system, shows a great potential to reduce NO X emissions [2,3]. The application of this technique to spark ignition and compression ignition engines has been studied with regard to its effects on engine performance, inlet air temperature control, combustion control and dual-fuel operation [4][5][6][7][8][9][10][11][12]. The possibility of reducing NO x emissions with the use of EGR rate results from thermal, chemical and dilution effects [8,9,[13][14][15][16].…”

“…O aumento da taxa líquida de liberação de calor pode aumentar as temperaturas locais da estrutura do cilindro, sendo necessária a avaliação da eficiência do sistema de arrefecimento do motor. Os resultados apresentados tiveram comportamento semelhante aos mostrados pelas referências [13,23,28,31].b Em cargas altas o aumento do atraso de ignição causado pela injeção indireta do etanol resulta em maior quantidade de combustível queimada na fase pré-misturada, que, juntamente com a combustão do óleo diesel em uma mistura ar-etanol mais rica, levam ao aumento do pico de pressão e da taxa de liberação de calor. (Fig.…”

“…Diversos estudos indicam redução das emissões de NOX e fuligem com a utilização de misturas de óleo diesel e etanol [10,13,18,[20][21][22][23][24][25][26][27], mas com possibilidade de aumento, principalmente com o aumento da pressão no interior do cilindro [25,[27][28][29][30] A adição de etanol pode aumentar as emissões de hidrocarbonetos não queimados e CO [10,13,18,[21][22][23][24][25][26]30]. A eficiência de conversão de energia do combustível também é dependente das condições de operação, havendo relatos de redução ou aumento com a adição de etanol [10,13,21,25].…”

“…To overcome the aforementioned engine load and control challenges and to take advantage of specific fuel properties, such as the volatility, cetane, and octane numbers, alcohol fuels have drawn increasing attention from engine researchers [19][20][21][22][23][24][25][26]. Various fueling strategies of introducing alcohol fuels into the combustion chamber have been investigated, such as using fuel blends of diesel and ethanol or gasoline and ethanol.…”
