| description | One concept relates to a method of controlling fuel reforming within an internal combustion engine exhaust line. Fuel injections are controlled using a predicted temperature, the predicted temperature being a temperature that would occur at some point in the future if predetermined assumptions are met. Preferably, the prediction is made using a model that includes terms for hydrocarbon storage and subsequent reaction within the fuel reformer. The method improves reformer temperature control, particularly over periods during whch the fuel supply to the reformer is pulsed. the scope of the invention also includes methods wherein a temperature is not specifically predicted, provided the control method takes into account hydrocarbon storage and subsequent reaction.
L'invention concerne un procédé de contrôle du reformage de combustible dans une ligne d'échappement d'un moteur à combustion interne. Les injections de combustible sont contrôlées au moyen d'une température prévue, la température prévue étant une température atteinte ultérieurement à un certain moment si les hypothèses prédéterminées se confirment. Cette prévision est, de préférence, obtenue à l'aide d'un modèle contenant les termes de stockage des hydrocarbures et leur réaction ultérieure dans le reformeur de combustible. Ce procédé permet d'améliorer le réglage de la température du reformeur, en particulier lors de périodes pendant lesquelles l'injection de combustible dans le reformeur est pulsée. L'invention concerne également des procédés sans prévision de température spécifique, à condition que le procédé de contrôle prenne en compte le stockage des hydrocarbures et leur réaction ultérieure. |
