Abstract

AL'INVENTION CONCERNE UN PROCEDE ET UN DISPOSITIF POUR LE REGLAGE DU COEFFICIENT D'AIR LAMBDA DANS UN MOTEUR DIESEL A AUTO-ALLUMAGE. B.ON DETECTE, AVEC AU MOINS UNE SONDE A COURANT D'IONS 9 L'IMPORTANCE DE LA POST-COMBUSTION DES COMPOSANTS GAZEUX A LA SORTIE DU MOTEUR QUE L'ON COMPARE SOUS LA FORME D'UN COURANT D'IONS, COMME GRANDEUR DE REGULATION DANS UNE INSTALLATION 10 DE REGULATION, A UNE VALEUR DE CONSIGNE PREDETERMINEE, ET IL EST EXERCE UNE ACTION, EN FONCTION DU RESULTAT OBTENU, SUR UN DISPOSITIF DE REGLAGE 46 QUI MODIFIE LE COEFFICIENT D'AIR L DANS LE MELANGE CARBURANT-AIR. C.CE PROCEDE PERMET, DANS LA MARCHE DES MOTEURS DIESEL, DE SE RAPPROCHER NETTEMENT PLUS QU'IL N'EST COURANT DE LA LIMITE D'EMISSION DE FUMEE CHARGEE DE SUIE, ET DE MAINTENIR LE COEFFICIENT D'AIR L NECESSAIRE A CET EFFET AVEC UNE PLUS GRANDE SECURITE.
