Title (EN) SUPERCHARGER ASSEMBLY WITH INDEPENDENT SUPERCHARGERS AND MOTOR/GENERATOR
(FR) ENSEMBLE DE COMPRESSEURS DE SURALIMENTATION AVEC COMPRESSEURS DE SURALIMENTATION INDÉPENDANTS ET MOTEUR / GÉNÉRATEUR
Abstract:
(EN) An assembly for controlling air flow to an engine includes a first supercharger(20) and a second supercharger (22). The superchargers are arranged in parallel with one another and in series with the throttle (70) in the air flow to the engine cylinders, and are configured to be operatively connectable with the engine upstream in the air flow to the cylinders. The assembly includes a load device (38) selectively connectable to the first supercharger (20) and selectively alternately operable to provide energy to or receive energy from the first supercharger. The superchargers are configured to be separately selectively operatively connectable with the throttle and the crankshaft to enable different modes of operation.
(FR) L'invention concerne un ensemble destiné à réguler le débit d'air vers un moteur thermique, comprenant un premier compresseur de suralimentation et un deuxième compresseur de suralimentation. Les compresseurs de suralimentation sont disposés en parallèle entre eux et en série avec le papillon des gaz dans l'écoulement d'air en direction des cylindres du moteur thermique, et sont configurés pour pouvoir être reliés fonctionnellement au moteur thermique en amont dans l'écoulement d'air vers les cylindres. L'ensemble comprend un dispositif de charge susceptible d'être relié sélectivement au premier compresseur de suralimentation et de fonctionner sélectivement alternativement pour céder de l'énergie au premier compresseur de suralimentation ou recevoir de l'énergie de celui-ci. Les compresseurs de suralimentation sont configurés pour pouvoir être reliés fonctionnellement sélectivement et séparément avec le papillon des gaz et le vilebrequin de façon à autoriser différents modes de fonctionnement.
