Title
(DE) VORRICHTUNG UND VERFAHREN ZUM BETREIBEN EINES MESSFÜHLERS FÜR GASE, INSBESONDERE EINER LAMBDASONDE
(EN) DEVICE AND METHOD FOR THE OPERATION OF A GAS SENSOR, ESPECIALLY A LAMBDA PROBE
(FR) DISPOSITIF ET PROCEDE POUR FAIRE FONCTIONNER UN CAPTEUR DE MESURE DE GAZ, NOTAMMENT UNE SONDE LAMBDA
Abstract
(DE) Vorrichtung und Verfahren zum Betreiben eines Messfühlers für Gase, insbesondere einer Lambdasonde, wobei der Messfühler eine Heizung aufweist, und der Messfühler vor einem Start einer Brennkraftmaschine aufgeheizt wird.
(EN) Disclosed are a device and a method for operating a gas sensor, particularly a lambda probe. Said sensor is provided with a heater and is heated before an internal combustion engine is started.
(FR) L'invention concerne un dispositif et un procédé pour faire fonctionner un capteur de mesure de gaz, notamment une sonde lambda, qui présente un dispositif de chauffage permettant de le chauffer avant un démarrage d'un moteur à combustion interne.
