Abstract
The proposed technique makes use of a non-deformable sealed tank (10) of specific volume, a pressurized-fluid supply (30) equipped with a connector (31) intended to be connected to an orifice in the hollow component (50), a liquid delivery (20) for filling and emptying the tank, once the component has been submerged in it, and a sensor (40) for detecting the variation in volume of the liquid in the tank resulting from the deformations of the casing of the component which are caused by the set pressure of the fluid prevailing in it. The invention is used to assess the probable emission capacity of components during their design, in particular intake-line of motor-vehicle engines.
