Abstract

L'INVENTION CONCERNE UN INJECTEUR POUR L'INJECTION DE CARBURANT ET D'UN FLUIDE ADDITIONNEL, EN PARTICULIER DE L'EAU, DANS LA CHAMBRE DE COMBUSTION D'UN MOTEUR A COMBUSTION INTERNE A COMPRESSION D'AIR ET A INJECTION, EQUIPE D'UNE AIGUILLE D'INJECTEUR FERMANT UN CANAL DE SORTIE ET L'OUVRANT, EN DECOLLANT DE SON SIEGE, CONTRE L'EFFORT D'UN RESSORT DISPOSE DANS UN LOGEMENT DE RESSORT ET LA SOLLICITANT A LA FERMETURE. LE LOGEMENT DE RESSORT 9 EST PREVU POUR RECEVOIR UN FLUIDE ADDITIONNEL ET CE LOGEMENT DE RESSORT, JOUANT LE ROLE D'UNE CHAMBRE DE REFOULEMENT DE POMPE, EST EN COMMUNICATION PAR DES PERCAGES 10, 11, 12 PRATIQUES DANS L'AIGUILLE D'INJECTEUR 8 AVEC LA CHAMBRE DE COMBUSTION 13 LORSQUE LE CANAL DE SORTIE 2 EST OUVERT. LES DISPOSITIONS PREVUES PAR L'INVENTION PERMETTENT D'AMENER DE FACON SIMPLE A LA CHAMBRE DE COMBUSTION, A COTE DU CARBURANT USUEL, D'AUTRES FLUIDES LIQUIDES OU GAZEUX AMELIORANT LA MARCHE DU MOTEUR ET REDUISANT LES EMISSIONS GAZEUSES NOCIVES.THE INVENTION CONCERNS AN INJECTOR FOR THE INJECTION OF FUEL AND AN ADDITIONAL FLUID, IN PARTICULAR WATER, INTO THE COMBUSTION CHAMBER OF AN INTERNAL COMBUSTION ENGINE WITH AIR COMPRESSION AND INJECTION, EQUIPPED WITH AN INJECTOR NEEDLE CLOSING AN OUTLET CHANNEL AND OPENING IT, BY TAKING OFF FROM ITS SEAT, AGAINST THE FORCE OF A SPRING LOCATED IN A SPRING HOUSING AND REQUESTING IT TO CLOSE. THE SPRING HOUSING 9 IS INTENDED TO RECEIVE AN ADDITIONAL FLUID AND THIS SPRING HOUSING, ACTING THE ROLE OF A PUMP DISCHARGE CHAMBER, IS IN COMMUNICATION THROUGH DRILLS 10, 11, 12 PRACTICES IN THE INJECTOR NEEDLE 8 WITH COMBUSTION CHAMBER 13 WHEN OUTPUT CHANNEL 2 IS OPEN. THE PROVISIONS PROVIDED FOR BY THE INVENTION ALLOW TO BRING IN A SIMPLE WAY TO THE COMBUSTION CHAMBER, NEXT TO USUAL FUEL, OTHER LIQUID OR GASEOUS FLUIDS THAT IMPROVE ENGINE OPERATION AND REDUCE HARMFUL GASEOUS EMISSIONS.
