Abstract
Device for introducing exhaust gases recirculated from an internal combustion engine into the intake air supplied to such engine, in which the exhaust gas is divided into several flows that are introduced perpendicularly, through specific channels (3, 3'), into the intake air flow, preferably downstream of an elbow (8) on a duct (1) for such air.Method for recirculating exhaust gases in an internal combustion engine, in which such gases are introduced into the intake air by means of a device as described above, upstream of the intake manifold of the engine.
