An internal combustion engine is configured with combustion chamber pressure sensing and exhaust gas recirculation apparatus. Exhaust gas recirculation control includes closed-loop controlling exhaust gas recirculation apparatus in accordance with a predetermined control target. Adjustments to the control target are made based on combustion chamber pressure information. La présente invention concerne un moteur à combustion interne qui est configuré avec un dispositif de détection de pression de la chambre à combustion et un appareil de retour de gaz d'échappement. Le dispositif de commande de retour de gaz d'échappement comprend une commande en boucle fermée d'un appareil de retour de gaz d'échappement selon une cible de commande prédéterminée. Des ajustements de la cible de commande sont réalisés en se basant sur des informations de pression de la chambre à combustion.
