JIMENEZ, Dámazo N  y  SOLORIO, Francisco J. Unsteady Flow Field in a Model of the Intake Manifold of an Internal Combustion Engine. Inf. tecnol. [online]. 2007, vol.18, n.2, pp. 17-23. ISSN 0718-0764.  doi: 10.4067/S0718-07642007000200003.

The unsteady flow field generated in a simplified model of the intake manifold of an internal combustion engine containing a plenum and four runners is proposed and analyzed. The model is mounted in the intake system of an engine under motored conditions, driven by an electric motor. Instantaneous ensemble average velocities are obtained for 25 engine cycles and reported as a function of the crank angle for some representative points. Also, the global flow field is presented for selected crank angles, showing the evolution of the unsteady eddies produced near the runner inlet and the secondary flows generated in the plenum corners.
