Device for charging and stratifying recycled exhaust gases for an internal combustion engine, in particular for a motor vehicle and associated method

摘要

The device for charging and stratification of reprocessed exhaust gases, which is adapted to an internal combustion engine 2, in particular for a motor vehicle, comprises a cylinder head and at least one cylinder 3, above which the cylinder head defines a combustion chamber, the device comprising a pressure wave compressor 8 of the type is provided with a stator and a rotor formed of a plurality of channels, as well as with at least two lines 9, 10 for the inlet of compressed gases, comprising a mixture of fresh gases and recirculated exhaust gases derived from the combustion. The intake pipes are connected to the compressor 8 and designed to supply the cylinder of the engine, the quantities of reclaimed exhaust gases admitted being different from one pipe to another.
