Abstract

Procédé et dispositif de régulation de la température des gaz d'échappement d'un moteur à combustion interne équipé d'un dispositif de saisie de la température des gaz d'échappement (13), d'une consigne de température maximale des gaz d'échappement (12) et d'une commande pour la préparation du mélange selon les paramètres de rapport d'air comburant et de charge de cylindre.En cas de dépassement de la température maximale prédéfinie (12) des gaz d'échappement dans le mélange on diminue de manière continue ou en plusieurs étapes le rapport d'air comburant jusqu'à une valeur limite inférieure (22) et lorsqu'on atteint cette valeur limite inférieure (22) on réduit la charge des cylindres de manière continue ou en plusieurs étapes.Method and device for regulating the temperature of the exhaust gases of an internal combustion engine equipped with a device for entering the temperature of the exhaust gases (13), a maximum temperature setpoint for the exhaust gases. exhaust (12) and a control for the preparation of the mixture according to the parameters of combustion air ratio and cylinder charge. If the predefined maximum temperature (12) of the exhaust gases in the mixture is exceeded, The combustion air ratio decreases continuously or in several stages to a lower limit value (22) and when this lower limit value (22) is reached, the load on the cylinders is reduced continuously or in several stages.
