This paper aimed to evaluate the effects of air and fuel supercharge in an agricultural engine. Variables analyzed were torque, power and specific fuel consumption. Dynamometric experiments were carried out by means of the power take-off of an agricultural tractor. The experiment was conducted in a laboratory, with a completely randomized design in a bi-factorial arrangement, with three repetitions, six engine configurations being evaluated (Natural aspiration; Natural aspiration + Service; Turbocharged; Turbocharged + Service; Turbocharged + Intercooler; Turbocharged + Service + Intercooler) and 10 engine speeds (1,200; 1,300; 1,400; 1,500; 1,600; 1,700; 1,800; 1,900; 2,000 e 2,100 rpm). Results indicated that only the addition of the turbocharger does not increase the torque and power of the engine. The increase in fuel flow increases engine performance for any of the evaluated configurations. Turbocharged + Service and Turbocharged + Service + Intercooler configurations reduced specific fuel consumption by up to 10% and increased torque and power by approximately 30%, in relation to the original configuration (Natural aspiration).
