A compressed natural gas flow generating apparatus comprising: one or more gas supply (62); a pressure controller (65) for controlling the pressure of gas injected by the gas supply (62); a fuel rail (68) for providing gas to the engine from said pressure controller (65), the fuel rail (68) including a plurality of gas injectors (I1,I2,I3,I4) injecting gas and a plurality of gas injection tubes (23) coupled with the gas injectors (I1,I2,I3,I4), the gas injection tube (23) fixed to the inner wall (24a) of the intake port (24) of the cylinder head (30) by fixing means (40); a fuel supply line (80) for connecting the gas supply (62), the pressure controller (65) and the fuel rail (68); an electronic control unit (60) for outputting control signal in order to inject proper amount of the compressed natural gas to engine and electrically connected with the gas injectors (I1,I2,I3,I4), so that fast burn of the injected gas in the combustion chamber (22) is easily accomplished.

Appareil de mise en circulation de gaz naturel comprimé, comportant un ou plusieurs réservoirs de gaz (62); un régulateur de pression (65) servant à réguler la pression du gaz injecté à partir du réservoir de gaz (62); un distributeur de carburant (68) servant à alimenter le moteur (20) en gaz provenant dudit régulateur de pression (65), et comprenant plusieurs injecteurs de gaz (I1, I2, I3, I4) et plusieurs tubes d'injection de gaz (23) reliés aux injecteurs de gaz (I1, I2, I3, I4), chaque tube d'injection de gaz (23) étant fixé à la paroi interne (24a) de l'orifice d'admission (24) de la culasse (30) par un organe de fixation (40); une conduite d'alimentation en carburant (80) reliant entre eux le réservoir de gaz (62), le régulateur de pression (65) et le distributeur de carburant (68); et une unité de commande électronique (60) servant à produire un signal de commande dans le but d'injecter dans le moteur (20) une quantité appropriée de gaz naturel comprimé, et étant raccordée par voie électrique aux injecteurs de gaz (I1, I2, I3, I4) de manière à assurer sans difficulté une combustion rapide du gaz injecté dans la chambre de combustion (22).
