The device has a by-pass nozzle (30) e.g. three-way control valve, for by-passing exhaust gas and located downstream of a depollution unit. Exhaust gas recirculation conduits (32, 36) extend from the nozzle until an air intake system, which is constituted of an air filter (38) and an intake manifold (40). A part of the recirculation conduit (36) i.e. exhaust gas recirculation pipe, is made of a flexible polymer material e.g. silicone. A heat exchanger (34) is located downstream of the nozzle and upstream of the part of the conduit (36). |
