Abstract
This work aims to implement a measurement system for the airflow of an EA211 1.0 MPI Volkswagen engine. Based on the theoretical basis of mass flow calculation, a system was implemented in the laboratory that allowed obtaining, through the difference in pressure and air velocity and using ways to calibrate the measuring nozzle, the discharge coefficient of the entire system. From these data, it was possible to obtain the theoretical and absolute values of the mass flow of air entering the engine. With these results, it was possible to conclude that any sensor that measures pressure or flow must, considering experimental errors, coincide with the mass flow value obtained through the implemented system.
