Análise da eficiência de um grupo gerador elétrico com motor do ciclo otto funcionando na forma dual (gasolina/hidrogênio) em relação à sua configuração original

Abstract

This paper aims to analyze the hydrogen and gas mixture as a fuel to the Otto cycle engine, considering it as an alternative fuel. It is necessary to study about alternative fuels because of global concern with environmental problems. These problems are mostly caused by fossil fuel which may be considered a short source of energy in the future. Thus, the study used some experiments to analyze an engine’s work, in which it was used only gasoline, comparing it to the hydrogen engine, produced through electrolysis. The experiment data can be seen in comparative charts which showed a reduction in gasoline consumption and an increase in efficiency in cases that the hydrogen was used as an auxiliary fuel. The adoption of this technology faces obstacles like the high cost and level of danger, despite these problems have been solved as soon as the research about this issue has advanced. Understanding that the hydrogen is an abundant and a clean fuel with a great energy potential, it can be used as an energy source to vehicle engine as well as to other functions. It is for this reason that the hydrogen has been called “the fuel of the future”.
