Description

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).

This paper aimed to evaluate the effects of air and fuel supercharging in an agricultural engine. The analyzed variables consisted of torque, power, and specific fuel consumption. Tests were carried out using a dynamometer through the power take-off of an agricultural tractor. The experiment was carried out at a laboratory in a completely randomized design arranged under a two-factorial scheme, with three replications. Six engine configurations (natural aspiration, natural aspiration + service, turbocharger, turbocharger + service, turbocharger + intercooler, and turbocharger + service + intercooler) and 10 engine speeds (1,200, 1,300, 1,400, 1,500, 1,600, 1,700, 1,800, 1,900, 2,000, and 2,100 rpm) were evaluated. The turbocharger alone did not increase engine torque and power. The increase in fuel flow enhanced engine performance for the evaluated configurations. Turbocharger + service and turbocharger + service + intercooler configurations reduced specific fuel consumption by up to 10% and increased torque and power by approximately 30% compared to the original configuration (natural aspiration).
