Characterizing the admission flow in a spark ignition engine
##plugins.themes.bootstrap3.article.details##
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 (CD) and swirl (CT) 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 crosssectional planes and angular cylinder sections were made.
