Abstract

a. Moteur à combustion interne à acoustique améliorée; b. Moteur caractérisé en ce qu'il présente un habillage extérieur formant une enceinte constituant amortisseur acoustique, en ce que les appareils auxiliaires sont disposés à l'extérieur de l'enceinte et en ce qu'il est prévu un puits commun pour le passage des courroies trapézoïdales et de l'air de refroidissement de l'enceinte, puits qui forme amortisseur acoustique par absorption; c. L'invention s'applique à l'insonorisation des véhicules motorisés.
