Características de desempenho e emissões de um motor diesel movido a biodiesel de babaçu

Abstract

Fossil fuels are used in the automotive and industrial sectors, consequently the combustion can influence health problems and global climate change. Excess soot emissions cause air pollution, so seeking substitutes for petroleum-derived fuels is necessary. This study aims to use babassu coconut biodiesel blends utilized with diesel in a single-cylinder engine and its performance, combustion and emission behavior are analyzed with different loading conditions. Furthermore, it compares babassu coconut biodiesel with soybean biodiesel in terms of emissions and performance of an engine using blends of biodiesel (B0, B10, B15, B20, and B100). The engine was operated during the experimentation with a rated power of 2.5 kW resistances charges at 3600 rpm. The parameters measured are fuel consumption, exhaust temperature (EGT) of smoke emission, particulate matter (PPM), oxides of nitrogen (NOx), monoxide carbon (CO), hydrocarbons (HC), carbon monoxide (CO) and carbon dioxide (CO2 ) have been presented. The comparison shows that babassu biodiesel can substitute soybeans because the NOx emission was reduced at B100 in all charges compared to other fuels.
