Análise do desempenho energético do uso de biodiesel brasileiro em grupos geradores de pequeno porte

Abstract

The use of fossil fuels, such as diesel, in energy generation systems is one of the leading sources of pollutant emissions, emphasizing the need for cleaner and more sustainable alternatives. In this context, biodiesel emerges as a viable solution, particularly in sectors where energy efficiency and environmental impact reduction are crucial. This study provides a detailed analysis of Brazilian biodiesel in small-scale generators, focusing on its performance compared to conventional diesel. The main goal of this research is to evaluate the energy and environmental feasibility of using biodiesel as an alternative fuel, aiming to reduce pollutant emissions and improve energy efficiency in rural areas and sectors where diesel is commonly used. Tests were conducted using various biodiesel-diesel blends, evaluating parameters such as engine temperature, rotation, vibration, fuel consumption, and thermal efficiency. Results showed that a 50% biodiesel and 50% diesel mixture offered the best balance between consumption and performance, while 100% biodiesel increased fuel consumption. The research concludes that biodiesel is a viable alternative, but optimizations are required to maximize generator engine efficiency, particularly in terms of fuel consumption and emission control. This study contributes to the development of sustainable energy solutions in Brazil, especially for rural producers and local industries.
