Abstract

Dispositif dans lequel le gaz d'échappement recyclé est introduit dans le carburateur entre le venturi et le papillon des gaz. Le carburateur comprend un starter 2 avec un volet d'air 5, une portion diffusante 6 avec un petit venturi 6a et un grand venturi 6b, une portion commande des gaz 4 avec un papillon 7, des orifices de ralenti 15 et 16. Une portion de gaz recyclée venant du moteur 22 par la ligne 24, dérivée en deux portions 24a et 24b contenant des valves 26 et 35, suit les lignes 21 et 34 qui contiennent des orifices calibrés 32 et 36. Une arrivée d'air supplémentaire se fait par le conduit d'air 27 débouchant sur l'orifice 30. Le mélange air-gaz recyclé pénètre dans le carburateur par l'orifice 25.
