Abstract

LA PRESENTE INVENTION CONCERNE UN SYSTEME DE COMMANDE DU MELANGE DE CARBURANT ET D'AIR DANS UN MOTEUR A COMBUSTION INTERNE. CE SYSTEME EST CARACTERISE EN CE QU'IL COMPORTE UN CAPTEUR DE DEBIT DE CARBURANT 22 RELIE A LA CANALISATION 16 D'ALIMENTATION EN CARBURANT, UN CAPTEUR D'ECOULEMENT D'AIR 26 RELIE AU DISPOSITIF D'ENTREE D'AIR 20, UN DISPOSITIF DE CALCUL DE PROPORTION 30 CONNECTE AUX SORTIES DES DEUX CAPTEURS 22 DE DEBIT DE CARBURANT ET 26 DE DEBIT D'AIR, POUR DELIVRER UN SIGNAL DE SORTIE REPRESENTANT LE RAPPORT ENTRE LES DEBITS DE CARBURANT ET D'AIR (RAPPORT CARBURANTAIR) POUR LE MOTEUR, UN DISPOSITIF 40-48 PRODUISANT UN SIGNAL DE RAPPORT DE REFERENCE CARBURANTAIR AFIN DE DELIVRER UN SIGNAL DE SORTIE REPRESENTANT LE RAPPORT OPTIMAL CARBURANTAIR POUR UNE CONDITION DE FONCTIONNEMENT DONNEE DU MOTEUR, DES MOYENS 36 POUR COMPARER LE SIGNAL DE SORTIE DU DISPOSITIF DE RAPPORT DE REFERENCE 40-48 AVEC LE SIGNAL DE SORTIE DU DISPOSITIF DE CALCUL DE PROPORTION 30 ET POUR PRODUIRE UN SIGNAL DE SORTIE REPRESENTANT LA DIFFERENCE ENTRE LES DEUX SIGNAUX D'ENTREE, ET DES MOYENS 54, 56 REPONDANT AU SIGNAL DE SORTIE DES MOYENS DE COMPARAISON POUR COMMANDER LA VANNE 60 D'ALIMENTATION EN CARBURANT.
