Abstract

The device comprises, for each intake chamber of the engine, an air intake pipe T and a fuel sprayer 7, 8 connected to a supply intake 9 situated on the fuel pipe 10 supplied with fuel under pressure by a pump 11. A throttle member 15, arranged downstream of the supply intake 9, regulates the pressure in the fuel pipe in accordance with the rate of air flow. This fuel pipe 10 is provided with a venturi V traversed by the flow of fuel and whose neck C is at relatively reduced pressure. The supply intake 9 is situated in the neck of this venturi. The invention is applied to internal combustion engines. <IMAGE>
