✦ Synopsis

Engenharia Térmica (Thermal Engineering), Vol. 9 №01 e 02, December 2010, 89-97 p.

This article presents a phenomenological combustion model using turbulent flame propagation theory developed by Keck and coworkers, 1974. The model was adapted to work with gasoline-ethanol blends, following correlations presented by Bayraktar,2005. New sub-models were introduced for intake valve velocity and combustion efficiency. These allow simulating the effect of compression ratio, spark timing and fuel change.
Results show good agreement with the ones in the original work as well as with experimental results in a Cooperative Fuels Research (CFR) engine.

Keywords: Internal combustion engine, ethanol, combustion, phenomenological model.
