ResumenEl objetivo del presente trabajo es mostrar los resultados de la medición de las componentes de la velocidad del aire admitido en el cilindro simulado de un motor CFR (Cooperative Fuels Research) instalado en un banco de flujo estacionario al cual se ha conectado un sistema de adquisición de datos. Para determinar las velocidades se empleó un anemómetro de hilo caliente previamente calibrado. Se realizaron mediciones sobre diferentes puntos de varios planos transversales del cilindro para diferentes levantamientos de la válvula de admisión. Como resultado de las pruebas se obtuvieron los perfiles de las velocidades sobre los planos considerados. A partir de estos perfiles se evidencia la presencia de vórtices o torbellinos de evolución axial y de evolución radial en el interior del cilindro.

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.
