Abstract

PROCEDE DE CONTROLE DE L'ETANCHEITE ET DU SIFFLEMENT D'INJECTEURS. UN FAISCEAU LASER 13 PASSE DEVANT L'ORIFICE 10 DE L'INJECTEUR 11, PUIS ATTEINT UN CAPTEUR PHOTOSENSIBLE 14, QUI LE CONVERTIT EN SIGNAUX ELECTRIQUES PROPORTIONNELS, TRANSMIS A UN TRADUCTEUR ELECTRONIQUE 16. POUR LE CONTROLE DU SIFFLEMENT, L'INJECTEUR EST ALIMENTE AVEC UN DEBIT DEFINI, SOUS UNE PRESSION DEFINIE. L'INJECTEUR EST CHARGE PENDANT LA DUREE DE CONTROLE D'ETANCHEITE PAR UNE PRESSION LEGEREMENT INFERIEURE A SA PRESSION D'OUVERTURE.PROCEDURE FOR CHECKING THE SEALING AND WHISPING OF INJECTORS. A LASER BEAM 13 PASSES IN FRONT OF PORT 10 OF INJECTOR 11, THEN REACHES A PHOTOSENSITIVE SENSOR 14, WHICH CONVERTS IT INTO PROPORTIONAL ELECTRIC SIGNALS, TRANSMITTED TO AN ELECTRONIC TRANSLATOR 16. TO CHECK THE WHISTLE, THE INJECTOR IS POWERED WITH A DEFINED FLOW UNDER A DEFINED PRESSURE. THE INJECTOR IS CHARGED DURING THE TIGHTNESS CHECK BY A PRESSURE SLIGHTLY LOWER THAN ITS OPENING PRESSURE.
