The engine (12) has an outlet case (24) and an air supply line (14) for supplying air to the engine. The air supply line comprises an exhaust gas recirculation loop (10) with a passage conduit (22) that is passed through the case. A filter (26) of the supply line stops particles at a catalytic phase, and is arranged in the conduit. The supply line comprises an air cooler (44) for cooling part of gas circulating in the loop of the line. The line comprises two air conduits (50) and an air stopper that is connected to the air conduits. The catalytic phase comprises a noble metal that is chosen in a group comprising platinum and palladium.
