Estudio del comportamiento de un motor ciclo Otto de inyección electrónica respecto de la estequiometría de la mezcla y del adelanto al encendido para la ciudad de Cuenca

Abstract

The city of Cuenca is located at 2550 meters above sea level, resulting in reduction of engine power of motor vehicles due to the decrease in atmospheric pressure and the amount of oxygen in the air, bringing an increase in the emission of pollutants in the exhaust gas and increased fuel consumption. To this must be added the types of fuels available in the market, which generate different responses in internal combustion engines. Using a factorial experimental design of two levels with intermediate points the degree of influence that the extra gas and super addition to the stoichiometry of the mixture and the advancement to power in motor operation is determined. Based on optimizing the engine operating point is modified achieving improved performance in a 1.59% concentration and reduce emissions to 8%.
