Abstract | The invention concerns an acoustic measuring device (1) for an exhaust turbocharger, with a compressor housing (2) which comprises a compressor housing inlet (3), a compressor impeller (4), a compressor spiral (5) and a compressor housing outlet (6); with a rotation speed sensor (7) arranged in the compressor spiral (5); with a measurement tube (8) which is connected to the compressor housing outlet (6) and has at least one dynamic pressure sensor (9, 10); with a flexible intermediate pipe (11) which is connected to the measurement tube (8) downstream viewed in the flow direction (R) of the air (L) emerging from the compressor housing outlet (6); with a silencer (12) which is connected to the intermediate pipe (11) downstream; and with a Laval nozzle (13) which is connected to the silencer (12) viewed in the flow direction (R).
L'invention concerne un dispositif de mesure acoustique (1) pour un turbocompresseur d'échappement, ledit dispositif comprenant un carter de compresseur (2) qui comprend un orifice d'entrée de boîtier de compresseur (3), une roue de compresseur (4), une spirale de compresseur (5) et un orifice de sortie de boîtier de compresseur (6) ; un capteur de vitesse de rotation (7) agencé dans la spirale de compresseur (5) ; un tube de mesure (8) qui est raccordé à l'orifice de sortie de boîtier de compresseur (6) et comporte au moins un capteur de pression dynamique (9, 10) ; un tuyau intermédiaire flexible (11) qui est raccordé en aval au tube de mesure (8) lorsqu'on regarde dans la direction de circulation (R) de l'air (L) qui sort de l'orifice de sortie de boîtier de compresseur (6) ; un silencieux (12) qui est raccordé en aval au tuyau intermédiaire (11) ; et une buse de Laval (13) qui est raccordée au silencieux (12) lorsqu'on regarde dans la direction de circulation (R). |
