O país dispõe de mais de 350 milhões de litros de óleo de frango por ano. Considerando a aplicação dos combustíveis alternativos para os motores a diesel, em máquinas agrícolas, o trabalho teve por objetivo avaliar o desempenho do motor de um trator agrícola de 53kW acoplado pela TDP em bancada dinamométrica, operando com biodiesel metílico de óleo de frango e misturas com óleo diesel, sendo: B5 (testemunha), B20, B40, B60, B80 e B100. Avaliaram-se a potência, o torque, a reserva de torque, o consumo de combustível, o consumo de energia e a eficiência térmica do motor. O ensaio foi instalado com delineamento inteiramente casualizado (DIC) em esquema fatorial com seis tratamentos. Os resultados foram submetidos à análise de variância e as médias ajustadas por equações de regressão. Foram observadas perdas na geração de potência e torque, aumento no consumo de combustível, redução do consumo energético e melhoria na eficiência térmica do motor, de acordo com o aumento da proporção de biodiesel na mistura. Brazil, the world third largest producer of biodiesel, and also the third largest producer of chicken, may increase the energy matrix, using oil derived from chicken, as an alternative to fossil fuels and reduce dependence on soybean oil for this purpose. The country can produce over 350 million liters of chicken oil per year. Considering the application of alternative fuels on diesel engines in agricultural machinery. The study aimed to evaluate the performance of a engine agricultural tractor with 53kW coupled by PTO in dynamometer bench operating with methyl biodiesel oil chicken and mix with diesel oil. Fuels B5 (reference), B20, B40, B60, B80 and B100 mixtures were used. The power, torque, torque reserve, fuel consumption, energy consumption and thermal efficiency of the engine were evaluated. The trial was conducted with a completely random design (CRD) in a factorial design with six treatment, which was held after the analysis of variance and adjusted means for the regression equations. Losses were observed in the generation of power and torque, increase in fuel consumption, reduction of energy consumption and improvement in engine thermal efficiency, according to the increasing proportion of biodiesel in the blend.
