Abstract

APPAREIL DE DETECTION DE RAPPORT AIRCARBURANT. L'APPAREIL DE DETECTION DE RAPPORT AIRCARBURANT SELON LA PRESENTE INVENTION COMPREND UN FIL 12 ELECTRONIQUEMENT CONDUCTEUR, UNE COUCHE 13 D'ELECTROLYTE SOLIDE CONDUCTEUR DE L'ION OXYGENE EN CONTACT DIRECT AVEC LA SURFACE DU FIL ELECTRONIQUEMENT CONDUCTEUR, UNE COUCHE 14 ELECTRONIQUEMENT CONDUCTRICE EN CONTACT DIRECT AVEC LA SURFACE DE LA COUCHE D'ELECTROLYTE, ET UN DETECTEUR DE TENSION 17 POUR DETECTER UNE FORCE ELECTROMOTRICE DEVELOPPEE ENTRE LE FIL ET LA COUCHE ELECTRONIQUEMENT CONDUCTEURS, DE MANIERE A SUPPRIMER AINSI UN ELEMENT DE BASE STRUCTURELLE RELATIVEMENT GRAND ELECTRIQUEMENT NON CONDUCTEUR QUI EST UTILISE DANS L'APPAREIL CLASSIQUE DE DETECTION DE RAPPORT AIRCARBURANT.AIRFUEL REPORT DETECTION DEVICE. THE AIRFUEL RATIO DETECTION APPARATUS ACCORDING TO THE PRESENT INVENTION INCLUDES AN ELECTRONICALLY CONDUCTIVE WIRE 12, A LAYER 13 OF SOLID ELECTROLYTE CONDUCTING THE OXYGEN ION IN DIRECT CONTACT WITH THE SURFACE OF THE ELECTRONICALLY CONDUCTIVE WIRE, A LAYER 14 ELECTRONICALLY IN CONDUCTIVE CONTACT. DIRECT WITH THE SURFACE OF THE ELECTROLYTE LAYER, AND A VOLTAGE DETECTOR 17 TO DETECT AN ELECTROMOTOR FORCE DEVELOPED BETWEEN THE WIRE AND THE ELECTRONICALLY CONDUCTIVE LAYER, SO AS TO REMOVE A BASIC STRUCTURAL ELEMENT RELATIVELY LARGE ELECTRICALLY USEFULLY LARGE IN THE CLASSIC FUEL RATIO DETECTION DEVICE.
