Abstract

L'invention propose un dispositif d'injection de gaz naturel dans une chambre de combustion (12) d'un moteur à combustion interne de véhicule automobile, du type comportant une chambre intermédiaire (26) de stockage de gaz naturel qui est équipée d'un injecteur (30) de gaz naturel qui est alimenté en gaz natureal par une conduite amont (32) d'alimentation, et du type dans lequel la chambre intermédiaire (26) communique avec la chambre de combustion (12) du moteur par l'intermédiaire d'une soupape d'injection (28) qui commande l'injection du gaz naturel dans la chambre de combustion (12), caractérisé en ce qu'il comporte une chambre complémentaire (38) contenant du gaz naturel qui est reliée à la chambre intermédiaire (26) par un canal de liaison (40) muni d'un clapet (42) dont l'ouverture permet d'augmenter la quantité de gaz naturel stocké dans la chambre intermédiaire (26) avant son injection dans la chambre de combustion (12).
