Abstract

CARBURATEUR A COMMANDE ELECTRONIQUE. LE CARBURATEUR 10 COMPREND UN PASSAGE D'ADMISSION 12 QUI COMMUNIQUE AVEC LE MOTEUR 16, UN MOYEN 26 D'ALIMENTATION DE CARBURANT POUR AMENER UNE QUANTITE REGLEE DE CARBURANT DANS LE PASSAGE D'ADMISSION EN CONFORMITE AVEC LE DEBIT D'AIR. UN MOYEN SECONDAIRE 32 D'ALIMENTATION DE CARBURANT, PREVU POUR ENVOYER DU CARBURANT COMPENSATEUR DANS LE PASSAGE D'ADMISSION, EST ASSOCIE AVEC UN MOYEN 34 DE MESURE DU DEBIT DE CARBURANT AFIN DE REGLER LE DEBIT DU CARBURANT DANS LE PASSAGE D'ADMISSION. LE FONCTIONNEMENT DU MOYEN DE MESURE DU DEBIT DE CARBURANT EST COMMANDE PAR UN ORDINATEUR 50 EN CONFORMITE AVEC LA QUANTITE D'AIR QUI S'ECOULE DANS LE PASSAGE D'ADMISSION ET AVEC L'IMPORTANCE DE LA VARIATION DE CETTE QUANTITE D'AIR. APPLICATIONS: NOTAMMENT A L'ALIMENTATION EN CARBURANT DES MOTEURS A COMBUSTION INTERNE.ELECTRONICALLY CONTROLLED CARBURETOR. THE CARBURETOR 10 INCLUDES AN INTAKE PASSAGE 12 WHICH COMMUNICATES WITH THE ENGINE 16, A FUEL SUPPLY MEANS 26 FOR DELIVERING A REGULATED AMOUNT OF FUEL IN THE INTAKE PASSAGE IN ACCORDANCE WITH THE AIR FLOW. A SECONDARY FUEL SUPPLY MEANS 32, PROVIDED TO SEND COMPENSATOR FUEL INTO THE INTAKE PASSAGE, IS ASSOCIATED WITH A MEASURING MEANS 34 OF THE FUEL FLOW IN ORDER TO ADJUST THE FLOW OF FUEL IN THE INTAKE PASSAGE. THE OPERATION OF THE MEASURING MEANS OF THE FUEL FLOW IS CONTROLLED BY A COMPUTER 50 IN ACCORDANCE WITH THE QUANTITY OF AIR FLOWING INTO THE INTAKE PASSAGE AND WITH THE IMPORTANCE OF THE VARIATION OF THIS QUANTITY OF AIR. APPLICATIONS: ESPECIALLY TO THE FUEL SUPPLY OF INTERNAL COMBUSTION ENGINES.
