Projeto de uma bancada de fluxo para cabeçotes de motores de baixa cilindrada unitária

Abstract

Flow benches are equipments used to measure the flow capacity of many components of Internal combustion engine using pressure drop generated by them, to accomplish this, it uses controlled pressure and temperature parameters. These machines are constantly used in high performance engines development, more specifically to evaluate modifications made in components like carburetors, intake manifolds and mostly in cylinder heads, where are made changes that can give significant increase of power. This paper proposes the project of a low cost flow bench designed to perform flow measurements in cylinder heads of engines with up to 500cc cylinder displacement, it may also be used to measure pressure losses in many devices in practical classes related to fluid mechanics.
