Abstract
The present invention relates to a method for reintroducing exhaust gas to the intake of an internal-combustion engine wherein, during the engine exhaust phase, part of the exhaust qas contained in combustion chamber () of cylinder () of the engine is fed, for an operating range of this engine, into a first fluid circulation circuit (C) and the other part of said gas is discharged into an exhaust circuit. According to the invention, the method consists: during the engine intake phase, in cooling the exhaust qas fed into fluid circulation circuit (C), in mixing the cooled recirculated exhaust qas with fresh supply air (AF) coming from engine supply circuit (), in feeding the mixture of recirculated exhaust gas and of supply air into a second fluid circulation circuit (C), and in cooling said mixture fed into second circuit (C) prior to feeding it into combustion chamber ().
