Abstract

L'invention concerne un circuit (10) de refroidissement pour un moteur (12) à combustion interne équipé d'un circuit de recirculation de gaz d'échappement, comportant au moins une première boucle (14) de refroidissement associée au moteur (12), une deuxième boucle (30) de chauffage qui comporte au moins un aérotherme (34), et une troisième boucle (40) de refroidissement des gaz d'échappement qui comporte au moins un échangeur thermique (42) pour refroidir les gaz d'échappement dudit circuit de recirculation, caractérisé en ce que ladite troisième boucle (40) de refroidissement des gaz d'échappement comporte au moins une pompe (44), des moyens (46) de chauffage pour chauffer sélectivement le liquide de refroidissement circulant dans ladite troisième boucle (40) et des moyens (48) de contrôle commandés sélectivement pour isoler la troisième boucle (40) par rapport au reste du circuit (10) de refroidissement. L'invention concerne également un procédé de commande d'un tel circuit (10) de refroidissement.
