DEVICE FOR MIXING A STREAM OF INLET GASES AND OF RECIRCULATED EXHAUST GASES COMPRISING INSULATING MEANS FOR THE RECIRCULATED EXHAUST GASES

摘要

The present invention relates to a mixing device (1) for mixing a stream of boosted air with a stream of recycled exhaust gas. The apparatus includes a manifold that allows a stream of air and a stream of recycled gas to be mixed therein and to allow the mixture to be dispensed into the cylinder head and a dispersed injection of recycled exhaust gas into the stream of boost air And conveying means (12) for conveying the recirculated exhaust gas in the manifold. The apparatus further includes adiabatic means (21) for inserting the conveying means (12) to limit the degree to which the recycled exhaust gas is cooled by the boost air.
