DEVICE FOR RECYCLING THE EXHAUST GASES OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention concerns a device for recycling the exhaust gases of an internal combustion engine comprising a circuit (2) for recycling the exhaust gases of an exhaust manifold to the induction pipe (1), the recycling circuit (2) comprising at one of its ends a tubular duct (3) for penetrating the induction pipe (1) through a corresponding opening (9) by projecting inside this induction pipe(1), said tubular duct (3) comprising a fastening ring (8) to be tightly clamped between the external surface of the induction pipe (1) and a flange (10) integral with the end of the circuit, characterised in that said fastening ring (8) comprises a boss (11) for enclosing said opening (9) to ensure the tightness of the device when the flange (10) is clamped.
