FYGUEROA, Simón J; ARAQUE, Jesús O  and  VILLAMAR, Carlos G. Velocity Profiles in an Alternative Engine Cilinder. Inf. tecnol. [online]. 2007, vol.18, n.1, pp.73-78. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642007000100011.

The present work objective is to show experimental results for speed components of air flow admitted in a CFR engine simulated cylinder (Cooperative Fuels Research), installed in a stationary flow bench provided with a data acquisition system. The speed components were measured using a calibrated hot wire anemometer. Measurements were made for different admission valve lifts on different points on several cylinder cross-sectional planes. As a result, the speed profiles on the planes considered in the study were obtained. From these profiles the presence of swirl and tumble in the interior of the engine cylinder was verified

Keywords : CFR engine; flow bench; anemometer; swirl; tumble.
