The distributor (1) has a hollow body (2) constituted by assembling a tank forming part (2') and a cover forming part for defining a plenum (3) or a distribution chamber, where the parts are made of thermoplastic material. The hollow body is provided with an inlet opening (4), and inserts (5) are partially extended in the plenum. A metallic exhaust gas injection device (6) is in the form of a tubular conduit and injects a counter-flow exhaust gas in a fresh air or inlet gas flow entering the opening. A nozzle tip (8) is terminated at its free end by a closed flat end portion. |
