Abstract

A.INSTALLATION POUR CAPTER LES VIBRATIONS PRODUITES DANS LES MOTEURS A COMBUSTION INTERNE EN CAS DE PROCESSUS DE COMBUSTION ANORMAUX. B.CARACTERISEE EN CE QUE LA PRESSION REGNANT DANS LES CYLINDRES DU MOTEUR A COMBUSTION INTERNE EST PRELEVEE PAR AU MOINS UN TRANSMETTEUR DE VALEUR DE MESURE 1 EN SOI CONNU DISPOSE SUR LE VILEBREQUIN 7 ET OU SUR DES ELEMENTS ENTOURANT LE VILEBREQUIN 7. C.INSTALLATION APPLICABLE A UN MOTEUR A COMBUSTION INTERNE.A.INSTALLATION TO CAPTURE VIBRATIONS PRODUCED IN INTERNAL COMBUSTION ENGINES IN THE EVENT OF ABNORMAL COMBUSTION PROCESSES. B. CHARACTERIZED IN THAT THE PRESSURE IN THE CYLINDERS OF THE INTERNAL COMBUSTION ENGINE IS TAKEN BY AT LEAST ONE MEASURED VALUE TRANSMITTER 1 I KNOWN ON CRANKSHAFT 7 AND OR ELEMENTS SURROUNDING CRANKSHAFT 7. C. INSTALLATION APPLICABLE TO AN INTERNAL COMBUSTION ENGINE.
