Integrated controls for commercial dynamometers do not have appropriate characteristics to perform research and teaching tasks. These are developed to perform quick tests and its logic is prepared to obtaining the information in accordance with the technical standards. This way, the use for research is hindered because it does not have an interface that allows a refinement to the desired data ranges, t data sampling and the type of load that is applied. Its use for teaching is limited because these "standard" controls does not allow to analyze or to determine engines characteristics that are not covered through tests specified by the standards, so the use of this tool as an important part in professional training formed by the institution.

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.
