Abstract
The invention relates to a gas distribution manifold (3) in the cylinder head of a heat engine of a motor vehicle, said manifold (3) comprising a manifold housing (31) provided with an inflow face for the inflow of an admission gas (G) and an outflow face (3B) entering the cylinder head of the engine, and an injection spout (6) for injecting a recirculated exhaust gas flow (H) of the engine into the admission gas flow (G), the manifold housing (31) and the injection spout (6) forming a single component. As the injection spout (6) comprises an open face, the manifold (3) is configured such that said open face is closed by an element outside the manifold (3), especially the cylinder head, in such a way as to form a tubular injection pipeline.
