Abstract

Dans l'installation selon l'invention, la quantité d'air fournie par le turbo-alimenteur 11 est égale à celle consommée par le moteur à combustion interne 1 fonctionnant à pleine charge et à la moitié de sa vitesse de régime. A cette vitesse, le taux de compression du turbo-compresseur 5 se rapproche de la pression de suralimentation limitée par la pression de crête de combustion maximale admissible tandis que la quantité d'air fournie est au plus de 6-10 % supérieure à la consommation du moteur en air frais. Une valve de régulation 14 est disposée dans le conduit d'air frais 15 et est réglée sur la pression de suralimentation maximale en vue de décharger l'air excédentaire dans le conduit d'échappement 13.
