Abstract

L'invention concerne un moteur à combustion interne. Il comporte, pour chaque cylindre, un orifice auxiliaire d'admission, de section nettement inférieure à celle de l'orifice principal, de manière qu'au ralenti, et à bas régime, le mélange qui passe par cet orifice auxiliaire pénètre dans la chambre de combustion avec un fort mouvement tourbillonnant, améliorant ainsi le mélange et la propagation de la flamme. L'invention s'applique notamment aux moteurs à explosion de véhicules automobiles.The invention relates to an internal combustion engine. It comprises, for each cylinder, an auxiliary inlet orifice, of section markedly smaller than that of the main orifice, so that at idle speed, and at low speed, the mixture which passes through this auxiliary orifice enters the chamber. combustion with a strong swirling motion, thus improving the mixing and propagation of the flame. The invention applies in particular to internal combustion engines of motor vehicles.
