Abstract

Dispositif pour la récupération de l'énergie contenue dans les gaz d'échappement, dans lequel un moteur thermique (5) entraîné par un générateur de vapeur, entraîne à son tour une machine de travail (8). Pour assurer que lors de variations dans la puissance d'entrée le moteur thermique reste dans la plage de fonctionnement optimale, on prévoit un système de commande (11) qui règle la consommation énergétique de la machine de travail (8) en fonction de l'énergie introduite par l'échappement, de manière à limiter la consommation de la machine de travail, ce qui permet d'assurer que le moteur thermique fonctionne toujours dans la plage de fonctionnement optimale.
