Abstract

La présente invention a pour objet un procédé comportant les étapes suivantes : • détermination d'une quantité de carburant à injecter, • injection d'une injection principale et d'une post-injection (Post1), • mesure de la pression (P cyl) et détermination d'un couple produit (TQI) et d'un centre de combustion (AI50), • détermination d'une variation de quantité globale de carburant à injecter (AMF) en fonction de la différence entre une consigne de couple (TQI SP) et la mesure de couple produit (TQI). La variation de quantité globale de carburant à injecter comprend une variation de quantité de carburant (ΔMF2) principale et une variation de quantité de carburant (ΔMF3) de post-injection. La variation de quantité de carburant à injecter de post-injection est fonction de la différence (ΔTQI) entre la consigne de couple (TQI SP) et la mesure de couple produit (TQI) et de la différence (ΔAI50) concernant le centre de combustion.
