This paper aims to improve a device, installed in the Laboratory of Engines at the Instituto Federal de Santa Catarina (IFSC), used by students and professors for classes and researches of ADeMCI (Performance Evaluation of Internal Combustion Engines) research group registered on CNPq. This paper presents the development of an automated flowbench for test cylinder heads using electronic features as MAP (manifold absolute pressure) and MAF (manifold air flow) sensors, commonly used in automotive systems to control the fuel injection in engines. Automated flowbenchs already exist in the international market, but their costs are expensive for the acquisition. This kind of device allows a cylinder test to be executed in a short time, with greater accuracy readings without the direct influence of the operator's ability. The automation of a flowbench like this will increase the capacity of testing of the laboratory, allowing to train more students and to develop more researches.
