Evaluación de un motor de encendido por chispa trabajando con mezclas etanol-gasolina

in this investigation an analysis based on the performances of an engine when using blends of anhydrous ethanol with regular gasoline as fuels is carried out. the experiments of the lada 1300 engine were carried out for different blends in 10%, 20% and 30% of ethanol in gasoline. the analyzed parameters for each experiment were the effective torque, the effective power, the specific fuel consumption and the carbon monoxide exhausts emissions. the obtained results were statistically analyzed through multiple-sample comparison in the software statgraphics centurion xv.ii. this analysis was made with the objective of analyzing the possible differences among the evaluated parameters for each fuel to the same rpm. the appropriate percent of the anhydrous ethanol - regular gasoline blends for use in engine (lada) under the cuba conditions and without making modifications were satisfactorily established.
