Title (EN) METHOD FOR COMPENSATING VALVE DRIFT IN AN INTERNAL COMBUSTION ENGINE
(FR) PROCÉDÉ DE COMPENSATION D’UNE DÉRIVE DE SOUPAPE D’UN MOTEUR À COMBUSTION INTERNE
(DE) VERFAHREN ZUR KOMPENSATION EINES VENTILDRIFTS EINER BRENNKRAFTMASCHINE
Abstract:
(EN) The invention relates to a method for compensating valve drift in an internal combustion engine having a variable valve train; in said method, an actual value of the current operating state of the internal combustion engine is determined in an air expenditure map and compared to a desired value of the air expenditure map, whereupon the air expenditure map is corrected.
(FR) L’invention concerne un procédé de compensation d’une dérive de soupape d’un moteur à combustion interne à commande de soupapes variable, dans lequel une valeur réelle de l’état de fonctionnement actuel du moteur à combustion interne est déterminée dans une caractéristique de consommation d’air au moyen d’un capteur de débit massique (1) et est comparée à une valeur de consigne de la caractéristique de consommation d’air puis la caractéristique de consommation d’air est corrigée.
(DE) Die Erfindung bezieht sich auf ein Verfahren zur Kompensation eines Ventildrifts einer Brennkraftmaschine mit variablem Ventiltrieb, bei welchem mittels eines Massenstromsensors (1) ein IST-Wert des momentanen Betriebszustands der Brennkraftmaschine in einem Luftaufwandkennfeld ermittelt und mit einem SOLL- Wert des Luftaufwandkennfelds verglichen wird und nachfolgend das Luftaufwandkennfeld korrigiert wird.
