Abstract

Système de suralimentation pour moteur diesel. La turbine 22 du turbo-compresseur haute-pression HP 12 et la turbine 16 du turbo-compresseur basse-pression BP 10 sont alimentées en parallèle, par un branchement en parallèle 36-38, par les gaz d'échappement du moteur 2 recueillis au collecteur d'échappement 8 du moteur. Une vanne 40 permet de répartir des débits de gaz entre les deux turbines. Le système de suralimentation permet d'améliorer les conditions d'alimentation en air du moteur pour le fonctionnement à faible puissance.
