Summary:

The magnitudes and compositions of in-cylinder tumble ratio generated by each velocity components were computed at different intake valve lifts and distances along the direction of valve axis in this paper, based on the three-dimensional velocity data measured by hot-wire anemometry at intake valve periphery of typical SI engine intake ports (horizontal and sloping directed ports) in a steady flow rig. The effect of velocity profiles at above two intake ports exit on in-cylinder tumble generation was studied, and a microscopic analytical method of evaluating tumble-generating capability of intake ports was developed according to the velocity profiles at intake valve exit area
