Caracterización del flujo de admisión en un motor de encendido por chispa

The goal of this work is to characterize the gas exchange process in a spark ignition (MECH) CFR (cooperative fuels research) engine, by determining the gases' discharge (C_D) and swirl (C_T) coefficients, and measuring the admitted air speed components in a simulated cylinder installed in a stationary flow bench. In order to characterize the flow macrostructure, the AVL method of Internal Combustion Engine Institute was used, and to obtain the speeds, a hot wire anemometer was employed. Utilizing the anemometer, some measurements at different points from several cross-sectional planes and angular cylinder sections were made.
