Abstract
The method of the invention includes the injection of fuel in a first constant-volume measuring chamber () in which the pressure (P) and the temperature (T) are measured, and the partial draining of said first chamber into a second variable-volume measuring chamber () based on the movement of a piston (), said movement being measured, wherein the partial draining of the first chamber into the second chamber after an injection is carried out until the pressure (Po) existing in the first chamber before the injection is recovered. The draining of the first chamber into the second after each injection is carried out several times consecutively, and the second chamber itself is drained each time. The volumetric measures made by moving the piston () for each filling/draining of the second chamber are added in order to obtain a total volume. The method is useful for high injection rates.
