Conversión de un motor de gasolina mono cilíndrico a hidrógeno como estrategia para reducción de emisiones contaminantes en el Distrito Metropolitano de Quito

Abstract

In this technical project, a hydrogen generation system was developed through hydrolysis and its adaptation to a 4-stroke single-cylinder engine to reduce polluting emissions produced by the engine. In the first chapter, a study on hydrogen as a fuel for MEP engines was developed, and the types of fuels used in MEP engines were also analyzed, highlighting their obtaining, advantages and disadvantages of these. In the second chapter, a block design was made of how the hydrogen generation system is structured, which is hydrolysis, materials necessary to create a hydrogen generating cell with its step-by-step procedure for its assembly, in addition to creating a system electrical connection as a safety measure. As well as the characterization of the engine and the adaptation of the hydrogen system to the vehicle. In the third chapter, tests were carried out to analyze the polluting gases produced by the engine fueled with gasoline, hydrogen and a mixture of both, using a gas analyzer that helped us determine samples to determine the decrease in polluting gases accompanied by the tabulation of the data obtained. In the final chapter, using the MATLAB R2023b software, a comparison of the different tests carried out on the engine was developed and the behavior of HC, CO, 𝐶𝑂2 and Lambda with the different types of fuel.
