Title (DE) VERFAHREN ZUM ERKENNEN VON IRREGULÄREN VERBRENNUNGEN IN EINEM ZYLINDER EINER BRENNKRAFTMASCHINE
(EN) METHOD OF DETECTING IRREGULAR COMBUSTION IN AN ENGINE CYLINDER
(FR) PROCEDE POUR LA DETECTION DE COMBUSTIONS IRREGULIERES DANS UN CYLINDRE D'UN MOTEUR A COMBUSTION INTERNE
Abstract:
(DE) Die Drehzahl für jeden Zylinder wird an zwei Kurbelwellenstellungen (z1, z2) eines Zylinders erfaßt und eine irreguläre Verbrennung erkannt, wenn die Steigung des Drehzahlverlaufs einen Grenzwert (GW) unterschreitet.
(EN) The rates of rotation at two cam-shaft positions (z1, z2) for each cylinder are measured and irregular combustion considered to be detected if the gradient of the rate-of-rotation curve drops below a given threshold value (GW).
(FR) La vitesse de rotation pour chaque cylindre est mesurée sur deux positions de vilebrequin (z1, z2) d'un cylindre, et une combustion irrégulière est reconnue si la montée de la courbe de la vitesse de rotation est inférieure à une valeur-limite GW.
