Evaluación de la contaminación producida por un vehículo con sistema de inyección MPFI y GDI, mediante pruebas estáticas

Abstract

Currently, transport, in all its forms, is the main consumer of fossil fuels in Ecuador, so that represents a high degree of energy expenditure and potential environmental pollutants that must be taken into account. aims to evaluate the level of contamination of two injection technologies in provoked ignition engines, static test using different types of gasoline, for the selection of the best technology. The applied methodology is the static analysis of gases when using Extra, Super and Ecopaís gasoline in direct to indirect injection systems using a canister as a fuel carrier container. The analysis of the results is carried out using the Statgraphics software, which through the formation of combinations between the independent variables for the analysis of the variation of the dependent variables, thus identifying the least polluting fuel and power system in provoked ignition engines. , in the investigation it was determined that the direct injection system generates, in HC 54 ppm in the case when using Ecopaís gasoline, 42.75 ppm when using Extra gasoline and 31.75 ppm with Super gasoline, in the CO value it was obtained 0.45% in when using Ecopaís gasoline, 0.14% with Extra gasoline and 0.26% and the multipoint injection system generates in HC 1.25 ppm with Ecopaís gasoline, 0.75 ppm with Extra gasoline and 6 ppm when using Super gasoline, a CO value 0% with Ecopaís gasoline, 0% with Extra gasoline and 0% when using Super gasoline and in the case of O2 in value it is 0.7% with Ecopaís gasoline, 021% with Extra gasoline and 055% when using Super gasoline, of the above exposed it. It can be identified that the multipoint feeding system generates fewer pollutants and also that using Ecopaís gasoline is a very viable option.
