“…Poor part load efficiency due to lean homogenous charge was also reported for dual fuel engine operation [4-5, 7, 25]. Accumulation of premixed CNG with the intake air in the combustion chamber crevices during the compression stroke in DFC leads to increased HC emissions in the engine exhaust was reported [7,9,16,26]. Several methods of improving the poor low load characteristics, including throttling, EGR, increased inlet air temperature, or switching over to diesel mode was reported [7].…”

“…These automobiles release massive pollutants and many other harmful components to the environment, and the resulting air quality deterioration along with it. So the increasing global concern has causes to focus on the oxygenated diesel fuels because of the environmental pollutions from internal combustion engines [1]. Also, world is presently confronted with twin crisis of fossil fuel deflection and environmental degradation.…”

“…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].…”
