Análise da adição de REGR rico em hidrogênio em motores à combustão interna

Abstract

Fundamental for humanity, internal combustion engines are at the center of debates due to being thermal machines harmful to the environment. From the first engines conceived to the most advanced engines available on the current market, the progress is remarkable and, together with environmental preservation policies, this environmental impact has been mitigated. The present study explores a new way to minimize the negative effects that pollutants released by internal combustion engines have on the environment. Based on this, the hypothesis of adding the product of the catalytic reform of engine exhaust gases to the air-fuel mixture intake phase is studied. This product is a mixture that contains gases such as carbon monoxide and carbon dioxide, in addition to being enriched with hydrogen after catalytic reform. The thesis utilizes the Python programming language to create an internal combustion engine simulator, with the aim of evaluating the effectiveness of adding reformed exhaust gases in indicators such as thermal efficiency, specific fuel consumption, and the emission of pollutants like carbon monoxide, carbon dioxide, and nitrogen oxides.
