METHOD FOR CHARACTERIZING A FIELD OF SPEEDS OF A FLOW OF AIR FOLLOWING THE DISCHARGE OF AN INTERNAL COMBUSTION ENGINE SUPERVISOR SYSTEM

摘要

The invention relates mainly to a method of characterizing a velocity field of an air flow inside an air filter provided with a silencer, said air filter being integrated into a line of air. admission of an internal combustion engine equipped with a supercharging system, characterized in that said method comprises: - a step (101) for simulating a discharge inside said air filter, - a step (102) ) ultrasonic level measurement of an air flow generated by said discharge, and - a step (103) of transforming the ultrasonic level measurements into a mapping of the air flow velocity field.
