| description | A method for controlling the dilution air supply to a partial flow dilution tunnel in a gas sampling system (36) is provided. The gas sampling system is capable of testing and certifying internal combustion engines (16) under transient conditions and includes a partial flow dilution tunnel (38), master and slave mass flow controllers (80, 60) and a transient dilution air flow controlling arrangement (110). The transient dilution air flow controlling arrangement (110) measures the transient changes in intake air and varies the flow of diluent air to the partial flow dilution tunnel (38). By controlling the diluent air in this manner ensures that a particle sample can be taken at any time that is at a constant proportion to the exhaust flow rate.
L'invention porte sur un procédé de régulation de l'alimentation en air de dilution d'un tunnel de système d'échantillonnage (36) de gaz à dilution partielle du flux. Ledit système, qui permet de tester et d'homologuer les moteurs à combustion interne (16) dans des états transitoires, comporte: le susdit tunnel (38); des régulateurs maître et esclave (80, 60) du débit massique; et un dispositif de régulation (110) du flux d'air de dilution transitoire, qui mesure les variations transitoires de l'air admis et fait varier le flux d'air de dilution dans le tunnel (38). Cette façon de réguler l'air de dilution permet de prélever à tout moment un échantillon de particules en proportion constante du débit de sortie. |
