APLICAÇÃO VEÍCULAR DO GÁS HIGROGÊNIO COMO AUXILIADOR DE COMBUSTÍVEL ALTERNATIVO

Abstract

The scarcity of resources from fossil fuels, in line with the large quantities of polluting gases released into the atmosphere, are increasingly evident in the study of new technologies to mitigate the environmental impact caused, among them, the use of clean fuels and devices that can assist in the burning of fossil fuels in internal combustion engines. This work aims to study the obtaining of hydrogen gas through aqueous electrolysis, a process by which an electric current is passed through water and hydrogen is obtained by breaking the water molecule (H2O) into its fundamental particles hydrogen (H2) and oxygen ( O), made using a prototype hydrogen generator developed at the technological center of the Faculdade Evangélica de Goianésia and its implementation in an Otto cycle internal combustion engine, to measure the influence of hydrogen on combustion. To carry out the tests, a motorcycle was used to which the HHO gas generation system was coupled, connected to the vehicle's battery and the gas was led into the combustion chamber through the engine's air intake. It was found that there was a yield of around 40% after implementing the prototype in the vehicle's engine, going from an average consumption of 0.23 liters/hour to approximately 0.14 liters/hour. constant speed of 1500 rpm and an applied fuel mass of 0.05 liters. This percentage increased when the engine speed parameters were modified, and continued to be efficient at around 45% better at speeds around 3000 rpm. It was found that the hydrogen produced by the generator, acting as a fuel booster (gasoline), when injected into the engine, promoted a satisfactory economic improvement.
