Resumo
Preocupações com o esgotamento do petróleo, as demandas crescentes por energia e os regulamentos de emissões, tem motivado a comunidade científica a buscar alternativas estratégicas. Diante de tal contexto, a produção e a utilização do biodiesel em motores de ciclo diesel é um tema de muito interesse e representa uma janela de oportunidades para o Brasil, pois este é um combustível de cunho socioambiental, capaz de minimizar a emissão de poluentes advindos das emissões de escape. Entendendo que este é assunto que compreende as esferas econômicas, jurídicas e socioambientais, o presente trabalho teve por objetivo discorrer sobre os padrões para controle de emissões de escape em máquinas agrícolas, bem como comparar a opacidade da fumaça de um trator agrícola funcionando com óleo diesel B S50 e proporções (B0, B5, B15, B25, B50, B75 e B100) de biodiesel de palmeiras (babaçu, tucumã e buriti). A legislação brasileira está cada vez mais rigorosa em relação aos padrões de emissões advindas de gases de escape. Assim, na comparação com diesel BS50, notou-se que a opacidade da fumaça de um trator agrícola foi menor ao se aumentarem proporções de biodiesel, sendo que o biodiesel de babaçu (B100) foi o que apresentou melhor resultado para os fatores tipo e proporção de biodiesel.
Concerns about the depletion of oil, growing demands for energy and emissions regulations, have motivated the scientific community to get strategic alternatives. In this context, the production and use of biodiesel in diesel engines is a topic of great interest and represents a window of opportunity for Brazil, since this is a socioenvironmental fuel, capable of minimizing the emission of pollutants from emissions. Understanding that this is a subject that encompasses the economic, juridical and socioenvironmental spheres, the present work had as objective to discuss the standards for control of exhaust emissions in farm tractor test, as well measure the opacity of the smoke of a tractor running on diesel oil B S50 and proportions (B0, B5, B15, B25, B50, B75 and B100) of palm biodiesel (babassu, tucumã and buriti). Brazilian legislation is becoming more stringent in relation to emission standards from exhaust gases. Thus, in the comparison with diesel BS50, it was observed that the opacity of the smoke of an agricultural tractor was smaller when increasing proportions of biodiesel, being that the babassu biodiesel (B100) was the one that presented the best result for the type factors and proportion of biodiesel.
