Abstract

L'invention concerne les dispositifs de purification de gaz d'échappement d'un véhicule automobile. Certains de ces dispositifs sont munis d'une entretoise pour l'assemblage des substrats de dépollution qu'il est ensuite nécessaire de décomposer dès le premier démarrage. L'invention propose un procédé de contrôle d'un moteur thermique de véhicule automobile comportant les étapes successives de détection (201) d'un démarrage du moteur, la vérification (202) d'un paramètre d'activation (P1) d'une fonction de montée en température (Tgaz) des gaz de combustion dans la ligne d'échappement en cas de détection (201) du démarrage du moteur, l'activation (204) de la dite fonction de montée en température lorsque le paramètre d'activation (P1) autorise le déclenchement de ladite fonction, dans lequel ledit paramètre d'activation (P1) est configuré en fonction d'une durée détectée durant laquelle la température (Tgaz) des gaz de combustion est supérieure à une consigne de température prédéterminée (CST) de ladite fonction.The invention relates to devices for purifying the exhaust gas of a motor vehicle. Some of these devices are fitted with a spacer for assembling the depollution substrates which it is then necessary to break down from the first start-up. The invention proposes a method for controlling a heat engine of a motor vehicle comprising the successive steps of detecting (201) a starting of the engine, the verification (202) of an activation parameter (P1) of an temperature rise function (Tgas) of the combustion gases in the exhaust line in the event of detection (201) of the engine starting, activation (204) of said temperature rise function when the activation parameter (P1) authorizes the triggering of said function, in which said activation parameter (P1) is configured as a function of a detected period during which the temperature (Tgas) of the combustion gases is greater than a predetermined temperature setpoint (CST ) of said function.
