Title (EN) METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF A MOTOR VEHICLE WITH AN AUTOMATIC TRANSMISSION

Abstract:
(EN) The invention relates to a method for operating an internal combustion engine of a motor vehicle with an automatic transmission, wherein a torque provided by the internal combustion engine is reduced depending on the operating state of a powertrain of the motor vehicle. Depending on an excess of combustion air which occurs upon reducing the torque, said combustion air being supplied to the internal combustion engine by means of a turbocharger, the fuel combustion efficiency relating to the torque provided by the internal combustion engine is reduced in at least one combustion chamber of the internal combustion engine.
(FR) L’invention concerne un procédé permettant de faire fonctionner un moteur à combustion interne d’un véhicule à moteur avec une transmission automatique, procédé selon lequel un couple fourni par le moteur à combustion interne est réduit en fonction d’un état de fonctionnement d’une chaîne cinématique du véhicule à moteur. En fonction d’un excédent d’air de combustion intervenant lors d’une diminution du couple, air de combustion acheminé jusqu’au moteur de combustion au moyen d’un turbocompresseur à gaz d’échappement, un rendement d’une combustion de carburant, rapporté au couple fourni par le moteur à combustion interne, est réduit dans au moins une chambre de combustion du moteur à combustion interne.
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben einer Verbrennungskraftmaschine eines Kraftwagens mit einem Automatikgetriebe, bei welchem ein von der Verbrennungskraftmaschine abgegebenes Drehmoment in Abhängigkeit von einem Betriebszustand eines Antriebsstrangs des Kraftwagens verringert wird. In Abhängigkeit von einem beim Verringern des Drehmoments auftretenden Überschuss an Verbrennungsluft, welche der Verbrennungskraftmaschine mittels eines Abgasturboladers zugeführt wird, wird ein auf das von der Verbrennungskraftmaschine abgegebene Drehmoment bezogener Wirkungsgrad einer Verbrennung von Kraftstoff in wenigstens einem Brennraum der Verbrennungskraftmaschine verringert.
