Análisis de torque, potencias consumo de combustible y emisiones contaminantes a diferentes concentraciones de gasolina/etanol en un banco de pruebas motor corsa 1.6 LT. de la C.I.A

Abstract

This research focused on the analysis of torque, power, fuel consumption and polluting emissions at different concentrations of ethanol-gasoline on the corsa engine test bench 1,6 liter at the School of Automotive Engineering. It was carried out the inspection on the current state of the engine, fuel supply system, fuel injection system, it was also developed the engine maintenance and the measuring test tube was adapted. The mixtures of ethanol-gasoline were prepared at different concentrations with their respective densities and finally, it was analyzed the functional test of the engine. The results of testing fuel consumption, torque - power, and emissions of pollutant gases at different concentrations of ethanol-gasoline (5%, 10%, and 20%) were analyzed and tabulated according to the engine operating scheme in the order to be compared with the data obtained from the gasoline to 100%. The analysis of the results it was determined that: in fuel consumption the amount saved could reach a 16,33% at 950 rpm, and a saving of 14,69% at 350 rpm compared to 20% ethanol. In polluting emissions could be stated according to the standard NTE INEN 2204:2002 to 950 rpm can pass smoothly the vehicle revision to 5% and 10% of ethanol. The power decreases in 4,22% and torque with 1,47% compared to ethanol 20%. Through the results it was concluded that it is not possible to vary more than 5% the ethanol-gasoline mixing with ECU vehicle standard because it cannot help improving the engine performance of the test performed.
