Abstract
The useful power developed by the naturally aspirated engine is a function of the mass of air drawn in due to a pressure gradient generated between the atmosphere and the combustion chamber. The International SAE Regulation makes requirements for flow reducers to be installed in the intake system of Formula-SAE vehicles, reducing the mass of air supplied to the combustion chamber and affecting the behavior of the engine as a whole due to the increased pressure drop. The objective of this paper was to numerically and experimentally analyze the pressure loss generated by the restrictor, measuring the impact on the volumetric efficiency and fuel consumption. The numerical analysis was performed in a CFD environment. The results have concluded the need to resize the intake system in order for the racing vehicle to be built meet the project's goal, which is to reach 100 kmph in less than 6 seconds, with a final speed of about 140 kmph.
