ABSTRACT - This paper aimed to evaluate the performance of a Diesel cycle engine, changing the configurations for the air and fuel supply system. Variables analyzed were torque, power, specific fuel consumption and thermal efficiency in four different engine configurations (aspirated, aspirated + service, turbocharged + service and turbocharged). For that, there were dynamometer experiments by power takeoff of an agricultural tractor. The experimental outline used was entirely randomized, in a bifatorial design with three repetitions. Results indicated that the engine supercharge, compared to its original configuration, provided a significant increase of torque and power. Only the addition of turbo does not caused a significant effect in the engine performance. Application of turbocharger provides an improvement in the burning of the air/fuel mixture, which favors the increase of engine power and; consequently, reduced the specific fuel consumption.

Key words: agricultural tractor, turbocharger, injection pump, fuel consumption.</abstract>

RESUMO - Este trabalho teve como objetivo avaliar o desempenho de um motor ciclo Diesel, alterando a configuração do sistema de alimentação de ar e de combustível. As variáveis analisadas foram torque, potência, consumo específico de combustível e eficiência térmica em quatro diferentes configurações do motor (aspirado, aspirado + serviço, turboalimentado + serviço e turboalimentado). Para isso, foram realizados experimentos dinamométricos por meio da tomada de potência de um trator agrícola. O delineamento experimental utilizado foi inteiramente casualizado, em desenho bifatorial com três repetições. Os resultados indicam que, a sobrealimentação do motor, em relação à configuração original, proporciona aumento significativo do torque e potência. Somente a adição de turbo não causa efeito significativo no desempenho do motor. A aplicação do turbocompressor proporciona melhoria na queima da mistura ar/combustível, o que favorece o aumento da potência do motor e, consequentemente, reduz o consumo específico de combustível.

Palavras-chave: trator agrícola, turbocompressor, bomba injetora, consumo de combustível.</abstract>
