Abstract

L'invention concerne un procédé d'optimisation de la combustion d'un moteur à combustion interne fonctionnant en auto-allumage contrôlé dans lequel on mesure l'état de la combustion d'un mélange air/carburant dans la chambre de combustion (14) et, après traitement des signaux de mesure envoyés à une unité de traitement logique (46), on ajuste au moins un paramètre de contrôle de la combustion pour obtenir la combustion désirée pour les cycles suivants.
Selon l'invention, le procédé est caractérisé en ce que :
- on détermine plusieurs paramètres à ajuster pour optimiser la combustion ;
- on classe lesdits paramètres en paramètres rapides (PR) et en paramètres lents (PL);
- on gère les paramètres rapides (PR) par une boucle d'asservissement spécifique auxdits paramètres et on gère les paramètres lents (PL) par une boucle d'asservissement spécifique aux paramètres lents pour obtenir la combustion souhaitée pour les cycles suivants.
