Estudio del Comportamiento de un Motor Ciclo Otto de Inyección Electrónica Respecto al Grado de Concentración del Etanol en la Gasolina Extra para la Ciudad de Cuenca

Abstract

This research evaluates the performance (power, torque, fuel consumption, emissions and combustion pressure) motor vehicle Hyundai Getz 1.4 liters, with indirect electronic fuel injection, when subjected to performance tests with anhydrous ethanol and gasoline mixtures 86.5 octane. The Chapter 1 presents the state of the art on the use of ethanol as fuel, the theoretical foundations of the study variables, emission standards, and the state of pollution in the city of Cuenca. The Chapter 2 describes the equipment, methods, materials, competence of personnel involved in research and the environmental characteristics of place where the tests are developed. The Chapter 3 presents the analysis of the study variables, first the values obtained for E25, E50, E75, E100 regarding E0 fuels are compared, a mathematical model obtained and statistically validated by experimental design is also presented. At the end, emissions are analyzed with respect to the limits established in the rules. This study determined that the use of ethanol in gasoline improves power and torque, emissions of CO, HC decrease significantly, and NOx increase and even exceed the limits set by the EURO standards and the Chilean standard for engines ethanol. The application of statistical study allows a mathematical model that describes the behavior of the study variables for different concentrations of ethanol in gasoline; this is a great advantage because you can determine these variables without the need for tests that require spending resource.
