Abstract:
(EN) The invention relates to a method for operating an internal combustion engine (1), having the following steps: introducing a first defined quantity of a first gaseous fuel into a combustion chamber (3) of the internal combustion engine (1), in a first operating mode; introducing a second defined quantity of a second liquid fuel into the combustion chamber (3) at a defined injection time, inflaming the fuels in the combustion chamber (3), and detecting a knocking signal for the combustion chamber (3) in order to determine a knocking intensity, wherein, in the first operating mode of the internal combustion engine (1), the defined injection time is moved later within a first postponement range (VB1) if the determined knocking intensity exceeds a first smaller threshold value, wherein the determined injection time is moved later within a second postponement range (VB2), which is expanded in comparison to the first postponement range (VB1), if the determined knocking intensity exceeds a second, larger threshold value.
(FR) L'invention concerne un procédé permettant de faire fonctionner un moteur à combustion interne (1), le procédé comprenant les étapes consistant à : introduire une première quantité déterminée d'un premier carburant gazeux dans une chambre de combustion (3) du moteur à combustion interne (1) dans un premier mode de fonctionnement ; introduire une deuxième quantité d'un deuxième carburant liquide dans la chambre de combustion (3) à un moment d'injection déterminé ; allumer les carburants dans la chambre de combustion (3) ; et détecter un signal de détonnement pour la chambre de combustion (3) pour déterminer une intensité de détonnement, le moment d'injection déterminé étant retardé à l'intérieur d'une première plage de décalage (VB1) dans le premier mode de fonctionnement du moteur à combustion interne (1), lorsque l'intensité de détonnement déterminée dépasse une première valeur seuil plus petite, le moment d’injection déterminé étant retardé à l'intérieur d'une deuxième plage de décalage (VB2) étendue par comparaison à la première plage de décalage (VB1) lorsque l'intensité de détonnement déterminée dépasse une deuxième valeur seuil plus grande.
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben einer Brennkraftmaschine (1), mit folgenden Schritten: Einbringen einer ersten bestimmten Menge eines ersten gasförmigen Brennstoffs in einen Brennraum (3) der Brennkraftmaschine (1) in einer ersten Betriebsart; Einbringen einer zweiten bestimmten Menge eines zweiten flüssigen Brennstoffs in den Brennraum (3) zu einem bestimmten Einspritzzeitpunkt, Entflammen der Brennstoffe in dem Brennraum (3), und Erfassen eines Klopfsignals für den Brennraum (3) zur Ermittlung einer Klopfintensität, wobei in der ersten Betriebsart der Brennkraftmaschine (1) der bestimmte Einspritzzeitpunkt innerhalb eines ersten Verschiebungsbereichs (VBl) nach spät verschoben wird, wenn die ermittelte Klopfintensität einen ersten kleineren Schwellenwert überschreitet, wobei der bestimmte Einspritzzeitpunkt innerhalb eines zweiten, im Vergleich zu dem ersten Verschiebungsbereich (VBl) erweiterten Verschiebungsbereichs (VB2) nach spät verschoben wird, wenn die ermittelte Klopfintensität einen zweiten größeren Schwellenwert überschreitet.
