Abstract

Une turbine est placée dans la zone d'admission d'air d'un moteur à combustion interne, par laquelle le flux d'air doit passer pour arriver au moteur. La turbine est couplée à un arbre relié à une autre turbine se trouvant dans le système d'échappement du moteur, et à l'arbre menant du moteur par un accouplement électrique moteur/générateur. La turbine peut être actionnée par l'air se répandant dans l'admission d'air, de manière à refroidir l'air et fournir une sortie de puissance. L'air refroidi est ensuite utilisé par l'échangeur thermique pour en tirer un air frais que l'on peut injecter dans le compartiment des passagers ou pour tout autre installation. La turbine peut être actionnée par l'arbre de sortie du moteur ou par la turbine d'échappement comme compresseur ou turbocompresseur à suralimentation pour comprimer l'air admis dans le moteur et par là en accroître la puissance. Le système peut être commandé de manière à augmenter à volonté la puissance du moteur et faire des économies de carburant, grâce à l'énergie supplémentaire tirée de l'admission d'air, et à réaliser un conditionnement de l'air, ce qui permet de se passer d'un système de conditionnement d'air de type à fréon.
