An internal-combustion engine (1), in particular for a vehicle, is provided with a plurality of cylinders (2) and a cylinder head (3) which defines, for each cylinder (2), at least one exhaust duct (16) and at least one intake duct (12); the engine is further provided with an exhaust manifold (17) communicating with the exhaust ducts (16), and a system (27) for recirculating exhaust gas from the exhaust manifold (17) to the intake ducts (12); the system comprises a further manifold (13) which distributes the recirculated exhaust gases to the intake ducts (12) and communicates with the exhaust manifold (17) through a recirculation duct (37) provided at least partly directly in the cylinder head (3) which is provided with a heat exchanger (22) for cooling the recirculated exhaust gases. <IMAGE> |
