A manifold for dispersing the gas in the cylinder head of the engine, where the recirculated exhaust gas is mixed with the intake gas in a direction opposite to the direction in which the intake gas flows

摘要

The invention relates to a gas distribution manifold (3) in the cylinder head (4) 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, in such a way as to enable the circulation of the admission gas flow in the downstream direction in the manifold housing (31); and means for injecting a recirculated exhaust gas flow (H) of the engine into the admission gas flow (G). Said injection means are formed in the manifold in such a way that the recirculated exhaust gas flow is injected in a counter-flow to the admission gas flow.
