Abstract

Véhicule comportant un système d'enceintes d'isolation acoustique refroidies par air. Il comprend un compartiment radiateur 10, un compartiment moteur 4, pratiquement fermé, séparé du précédent par une cloison et disposé latéralement par rapport à celui-ci et un éjecteur utilisant les gaz sortant du tube d'échappement pour créer une pression relativement basse dans une ouverture de sortie d'air du compartiment moteur pour aspirer de l'air extérieur à travers le compartiment moteur. Application : véhicules, notamment de chantiers.
